what surface features on mars today indicate that there was significant water erosion in the past?

Answers

Answer 1

Broad and shallow outflow channels curve around obstacles like craters. They seem to have been caused by unexpected floods. Valley networks mimic drainage patterns and imply long-distance water movement, indicate that there was significant water erosion on Mars.

Currently, there may be very little liquid water on the surface of Mars, just evidence of dissolved atmospheric moisture and thin coatings, which are hostile settings for any known life. The idea that water existed on Mars dates back hundreds of years before the space age. Early telescopic viewers correctly inferred that the presence of clouds and white polar caps indicated the existence of water.

Astronomer William Herschel stated in 1784 that these discoveries, along with the knowledge that Mars had a 24-hour day, likely provided its people with "a position in many respects comparable to ours." The narrative shifted to portray Mars as a "dying" planet with scant water since the existence of seas was no longer acknowledged. The dark regions, which were seen to shift periodically, were formerly believed to represent large expanses of vegetation.

What is the term used to describe the land area where precipitation seeps into the soil and replenishes groundwater reserves

Answers

The term used to describe the land area where precipitation seeps into the soil and replenishes groundwater reserves is recharge area.

A recharge area is a location where water flows underground to replenish an existing water source, such as an aquifer or lake. When water seeps into the earth and replenishes aquifers below the surface, this process is known as recharge.

The quantity and/or quality of groundwater available for storage or usage will be negatively affected if recharge areas stop working as intended. Recharging areas need to be protected in a number of ways to accomplish two main goals:

Preventing areas suitable for recharge from being covered by urban infrastructure like buildings and roads.Keeping harmful substances out of the groundwater supply so that expensive treatment isn't required before the water may be used for its intended purpose.

Classify the triangle to the right by it's sides and angles?

Answers

An acute triangle has three angles that each measure less than 90 degrees. An equilateral triangle is a triangle in which all three sides are the same length. A right triangle is a triangle with one 90 degree angle.

What is a right triangle?

A triangle is said to have a right angle if one of the angles is 90 degrees. Right triangles are those with angles at 90 degrees, which are referred to as right angles.

The Pythagorean rule can be used to understand the relationship between the different sides of this triangle. The largest side, also known as the hypotenuse, is the side that forms the right angle.

The right triangles are further divided into isosceles and scalene right triangles based on the other angle values. The right triangle's side lengths, such as 3, 4, and 5, are also known as Pythagorean triples.

The total of the lengths of the three sides makes up the right triangle's perimeter. It is the right triangle's base, height, and hypotenuse added together.

Before sedimentary rock can be formed, sediment must be produced (weathered from preexisting rocks), transported, deposited, and lithified.

Sedimentary rocks are those that have accumulated over time and are composed of granules, ashes, and other detritus from preexisting rocks or extinct animals. They originate from waste products left on the planet's surface. The weathering of preexisting rocks, the transporting of the weathering products, the depositioning of the material, and finally the compacting and cementation of the sediment to form a rock, which is called lithification, are the processes that result in the formation of sedimentary rocks.

The Koppen Climate Classification System depends mainly on average daily temperature. The best answer is D. Average Daily Temperature.

The Koppen Climate Classification System is a widely accepted system used to classify and describe the world's climate based on average precipitation and temperature, vegetation, and other factors. The system is divided into five major climate groups: tropical, dry, temperate, continental, and polar. Within each of these major climate groups, there are numerous subcategories, each of which is defined by a different combination of temperature and precipitation.

Temperature is the key factor in the Koppen Climate Classification System. Average daily temperature is used to distinguish between the various climate groups, such as tropical climates, which have temperatures above 18°C (64.4°F) throughout the year, and polar climates, which have temperatures below -3°C (26.6°F) throughout the year.

why the terrestrial planets are closer to the sun than the gas giants?

Answers

The terrestrial planets formed close to the Sun where temperatures were well suited for rock and metal to condense.

Answer:

The planets in our Solar System formed from the solar nebula – the disc of gas left over from the formation of our Sun. Over time, this material began to collide and stick together, forming larger clumps that could collide with other larger clumps and gradually gather more and more matter. All of the planets in our Solar System began to form this way, but close to the Sun the temperature was too high for volatiles (gases like water and methane) to condense, so only the materials with a higher melting point (and higher density) were able to form at this point. The gas giants on the other hand, formed far enough away from the Sun that the temperature was cool enough for these volatile gases to condense, and form these huge, less dense planets.

Which of the following most likely accounts for acid precipitation occurring far from its point of origin, as indicated by the map

Answers

As indicated by the map precipitate production in a chemical reaction indicates that the reactants have not been fully transformed into the product and are not readily soluble in the solvent used.

Furthermore, because solubility product indicates the degree of solubility of the reactants, it is smaller than the ionic product for the specific salt or reactant. Therefore, portion of the reactant is left unreacted and undissolved when the precipitate is formed. The icons on the weather map are used to represent the pressures and temperatures in various zones.

C. Installments.

Explanation:

You pay it in Installments yearly. (Or it depends on the kind of loan you get, the time.)

The annual percentage rate is the interest on a loan paid in installments. Option (c) is correct.

What do you mean by Interest?

The fee you pay to borrow money or the fee you charge to lend money is called interest. The most common way to represent interest is as a yearly percentage of the loan amount. The interest rate on the loan is known as this percentage.

The cost of your mortgage credit expressed as a yearly rate is the annual percentage rate, or APR, of a loan. Your annual percentage rate, which is determined by the particulars of your loan and includes your interest rate as well as additional costs like lender and mortgage broker fees, is often greater than your interest rate.

Divided by the total number of days remaining on the loan term, the principal borrowed is multiplied by the interest rate plus all fees. The result is multiplied by 365 (which represents one year) and then by 100 once more.

how does the temperature of the air change as the air rises on the windward side of the mountain between sea level and 0.5 kilometers

Answers

The air temperature on the leeward side of the mountain at the 1.5-kilometer level is higher than the temperature at the same elevation on the windward side.

The Windward Side

This is the cold, wet side of the island. The windward side is constantly exposed to the wind, with cool, moist air blowing upwards. As this air is lifted by the drop in atmospheric pressure, it begins to cool. Cold air can't hold as much water vapor as warm air, so eventually, the moisture in the air begins to condense, and clouds form.

The Leeward Side

When condensation forms, the leeward side releases heat to the surrounding air. This effect is called the latent heat of condensation. As the air descends on the other side of an island or mountain, most of its moisture condenses. As the air continues to descend toward sea level, atmospheric pressure rises, resulting in rising temperatures. Because of all this warming, scientifically called adiabatic heating, the leeward side is generally warm and dry.

d. metals
e. certain organic materials less than 75,000 years old

Answers

Certain organic materials less than 75,000 years old would be best suited to the carbon-14 dating technique. Thus option C is the answer.

Carbon-14 dating is a technique used to determine the age of organic materials. It is based on the fact that the radioactive isotope carbon-14 (14C) is present in all living organisms, but it begins to decay at a steady rate after the organism dies. By measuring the amount of 14C in a sample of organic material, scientists can determine how long ago the organism died.

The carbon-14 dating technique is most accurate for determining the age of materials that are less than 75,000 years old. Beyond this age, the amount of 14C in the sample becomes too low to accurately measure. Therefore, materials older than 100,000 years would not be suitable for carbon-14 dating.

Volcanic rock and sedimentary rock are not organic materials and do not contain carbon-14. They are not suitable for carbon-14 dating. The same applies for metals, they are not organic and don't contain carbon-14.

The ways in which we use land in our cities and towns can have a significant impact on liveability and long-term sustainability. For example, incorporating green spaces and parks into urban areas can improve air quality, provide recreational opportunities, and increase biodiversity.

On the other hand, paving over green spaces and building densely packed high-rise buildings can lead to heat island effects, increased air pollution, and loss of biodiversity. In addition, planning and designing cities and towns with a mix of land uses, such as residential, commercial, and industrial areas, can promote walkability, reduce traffic congestion, and improve access to jobs and services.

What is the term used to describe nonrenewable groundwater reserves formed in the distant past that are no longer being replenished because of geologic and climatic changes

Answers

The term used to describe nonrenewable groundwater reserves formed in the distant past that are no longer being replenished because of geologic and climatic changes is “fossil groundwater”.

Fossil groundwater is a term used to describe water that has been stored for long periods of time in an aquifer, typically thousands of years, and is not being replenished or recharged by precipitation. As a result, it is not renewable and is considered a nonrenewable resource.

Fossil groundwater is usually found in arid regions, where the climate is dry and there is little precipitation to recharge the aquifer. It is also found in areas with limited recharge, such as those that have been affected by land use changes or areas that are geologically sealed due to tectonic activity. In some cases, fossil groundwater can be found in areas where the climate has changed significantly over time, such as in deserts or semi-arid regions.

Fossil groundwater is an important source of water for many people in arid areas, including farmers, ranchers and rural communities. This is because it is often the only source of water available in these areas. However, it is important to keep in mind that once it is used, it can not be recharged or replaced. As a result, it is essential to use this water wisely and conserve it whenever possible.
