TheQuestionIsWhy
give two examples of the thermal energy of a substance being decreased
Answer:
Adding ice to a glass of water causes the temperature of the water to decrease because the thermal energy in the water causes the ice to melt. A grill gives off thermal energy by burning propane.

Which galaxy will collide with the Milky Way in several million years? (1 point)
O Large Magellanic Cloud
O Local Group
O Andromeda Galaxy
O Sagittarius Dwart Galaxy
Answer: The Andromeda galaxy
Explanation:
And that's going to happen someday! The Andromeda galaxy is currently racing toward our Milky Way at a speed of about 70 miles (110 km) per second. Ultimately, the two galaxies will collide and merge.
Andromeda Galaxy collide with the Milky Way in several million years. Thus option C is correct.
What is Andromeda galaxy ?The Andromeda Galaxy (M31) which is the closest large galaxy to the Milky Way.
Around 4.5 billion years both Andromeda Galaxy and the Milky Way may be collide and form a giant elliptical galaxy.
Andromeda consist of 14 dwarf galaxies, M32, M110, and M33 galaxy.
It is supposed to Andromeda is the largest galaxy in the Local Cluster and most massive due to more dark matter in milk way galaxy.
Most of the astronomers use this Andromeda Galaxy to understand the origin and evolution of the galaxy.
This Galaxy called spiral galaxy has double nucleus, has massive stars, dust and one supermassive black hole hidden at the core region.
Thus option C is correct.

Sort the phrases based on whether they represent kinetic energy or potential energy.
Answer: The main difference between potential and kinetic energy is that one is the energy of what can be and one is the energy of what is. In other words, potential energy is stationary, with stored energy to be released; kinetic energy is energy in motion, actively using energy for movement

1. When did the first weather map come into being?
Answer:
1816
Explanation:
The earliest weather charts were made by collecting synchronous weather reports by mail. However, it was not until 1816 that German physicist Heinrich Wilhelm Brandes created the first weather maps, which were hand drawn and reconstructed from data collected in 1783.

1. List 2 interactions between the earth spheres and the water cycle.
2. List 2 interactions between the earth spheres and the carbon cycle.
3. List 2 interactions between the earth spheres and the nitrogen cycle.
Answer:
The carbon cycle, as the nitrogen cycle, occurs in all the spheres: Biosphere, Atmosphere, Geosphere and Hydrosphere.
Explanation:
Most Earth events involve interaction between multiple spheres. For example, rain is the movement of water (the hydrosphere) from the atmosphere to the lithosphere where it collects in lakes, rivers, or streams. Water is an important resource for inhabitants of the biosphere.
The Atmosphere-contains all the air in Earth's system. The upper portion of the atmosphere protects the organisms of the biosphere from the sun's ultraviolet radiation. It also absorbs and emits heat. This sphere is also where weather occurs.
The nitrogen cycle occurs in all the spheres and ecosystems. It passes through rocks, water, atmosphere, plants, etc.
In atmosphere and biosphere: Nitrogen is about 78% of the gases in the atmosphere an it’s a essential component of the living organisms. It enters plants through the microorganisms that convert this nitrogen into ammonia. After this conversion, the plants absorb this substance. It can pass to animals when they eat these plants. Then, when they urinate, bacteria convert ammonia to nitrogen again and it returns to the atmosphere.

How is biodiversity connected to healthy ecosystems? What is biodiversity?
Answer:
Below! : )
Explanation:
What is biodiversity? Well, in simple terms, biodiversity refers to all the variety of life that can be found on Earth (plants, animals, fungi, and micro-organisms) as well as to the communities that they form and the habitats in which they live. But how is biodiversity connected to healthy ecosystems? Well, many factors can contribute to this question but Biodiversity boosts ecosystem productivity where each species have an important role to play. With this in play we can see that it is healthy and keeps ecosystems safe.
