Describe how fossil fuels are converted into usable energy
:)
Answer:
Fossil fuel power plants burn coal or oil to create heat which is in turn used to generate steam to drive turbines which generate electricity.
Explanation:
Fossil fuels are used in power plants to make steam. Steam drives turbines which coupled to generator produce electrical energy. Electrical power is used in all industries, domestic used where energy is needed.
petroleum products like oil, gas are used in motor vehicles, ships, airplanes. They burn and give the power for transport.
Fossil fuels are burned under different conditions in engines, boilers, etc which produce heat energy and then converted into mechanical energy.
gas and oil are used to heat homes.
Answer: HEY HAVE A GREAT DAY
fossil fuels are converted into usable energy by first collecting, and then I'm pretty sure its turned into gas and turns turbines.
Explanation:
Fossil fuel are energy buried within the earth that could used as energy source for consumption. Most sources of earth's energy comes from fossil fuels

What are the different layers of the Earth, and how do they interact?
After Eris was discovered, scientists had to decide whether to count it as a planet. Why did this make them question whether Pluto should still be counted as a planet?
a
because Pluto and Eris are both space objects
b
because Pluto and Eris were discovered at the same time
c
because Pluto and Eris are very different
d
because Pluto and Eris are very similar
Answer:
After Eris was discovered, they had to decide whether Eris was a planet or not. If they decided it wasn't a planet, they had to also decide whether Pluto should be counted as a planet since Eris and Pluto were quite similar. They were the same size, and they were both part of the Kuiper Belt.
Explanation:
Planets are the celestial bodies that are not fixed. Pluto should be counted as a planet was a question as both Pluto and Eris were similar.
What are Pluto and Eris?Pluto is now considered a dwarf planet and is found in the Kuiper belt that is present beyond the planet, Neptune. Similarly, Eris is also a dwarf planet.
Eris is the second-largest dwarf planet and is very similar to Pluto. The discovery of Eris questioned whether Pluto should be considered a planet.
Both the planets Pluto and Eris were similar in size and were part of the Kuiper Belt leading to the question of whether they should be a planet or not.
Therefore, option d. Pluto and Eris are very similar.

The materials for this experiment are:
a smooth board
smooth block or other object to drag up a plane
a spring scale (calibrated in newtons)
string
books or blocks to support the inclined plane
and a meter stick.
Your job is to observe the experiment and collect your own data from this demonstration. Be ready to record your observations and data.
You will be pulling an object up an inclined plane at different inclines.
Make and record a hypothesis about how changine the slope of inclined plane will affect the efficiency.
Measure the height and length of the plane, record the measurements.
Measure the mass of the object, and record.
Convert the mass from grams to newtons by dividing by 102, and record.
Now slowly and steadily pull the object up the incline with the spring scale and string kept parallel to the incline.
Record the readout on the scale. This will be the effort force.
Now increase the slope of the incline by increasing the height.
Measure the height of the new incline. The length of the incline remains constant.
Slowly and steadily pull the object up the incline, record the readout from the scale.
Now increase the slope of the incline by increasing the height.
Measure the height of the new incline. The length of the incline remains constant.
Slowly and steadily pull the object up the incline, record the readout from the scale.
Now increase the slope of the incline by increasing the height.

How did the peak of Mt. Everest rise from sea level to 8,848 feet?
Answer:
The height of Everest. Controversy over the exact elevation of the summit developed because of variations in snow level, gravity deviation, and light refraction. The figure 29,028 feet (8,848 metres), plus or minus a fraction, was established by the Survey of India between 1952 and 1954 and became widely accepted.

Which describes the boundary where earthquake activity occurs along rift valleys?
Answer:
Divergent boundaries – where two plates are moving apart. Divergent boundaries within continents initially produce rifts, which produce rift valleys. The most active divergent plate boundaries are between oceanic plates and are often called mid-oceanic ridges.

How is science based on observation used as evidence? How can evidence be used?
Answer:
Explanation:
Researchers gather empirical evidence through experimentation or observation. Empirical evidence is information acquired by observation or experimentation. Scientists record and analyze this data. The process is a central part of the scientific method.
Answer:
Science Produces Explanations That Can Be Tested Using Empirical Evidence. Science requires that scientific explanations of phenomena be based on events or mechanisms that can be observed in the natural world. This is how science builds a base of shared observations and ideas to which new knowledge can be added.

Explanation:
Order the terms according to the path followed by oxygen during cellular respiration.
The respiration which is seen in plants and higher animals including humans take place in the presence of oxygen.
What is respiration?The process in which the cells of an organism obtain energy by the combination of oxygen and glucose and results in the release of carbon dioxide, water and ATP (energy) is defined as the respiration.
In respiration, the transfer of oxygen occurs from outside environment to cells within the tissues. It is a biological reaction which takes place inside the cells of living organisms. The energy molecule ATP ( Adenosine triphosphate) is created during this process.
The ATP molecule produced here by the breakdown of glucose is utilized by the cells to perform various activities. The first step in cellular respiration is glycolysis which occurs in cytoplasm.
The correct path of oxygen transfer is:
Nostrils → Nasal cavity → Pharynx → Trachea → Bronchi → Bronchiole → Alveoli
