All the other chices give evidence that supports that hypothesisthat the Moon was made of material that was flung off Earth during a time when it was rapidly spinning.
Explanation:
There is an enormous amount of similarities between the minerals in the moon rocks and the rocks on earth, except that for some minerals, like potassium, their quantities are higher on the earth than on the moon.
However, there is still supports for the evidence (by the other choices) that the moon was made from a piece of earth ejected from asteroid impact in primordial earth.Explanation:It’s believed that more than 3.5 billion years during the formation of earth and before it had cooled there were frequent asteroid impacts and one enormous collision ejected a large piece of molten earth into space but within earth’s gravity influence. This piece formed the moon. Evidence of asteroid impacts are frozen in time on the moon surface thanks to the fact that the moon has no atmosphere or tectonic plates movements that wipe off this ‘evidence’.

Answers with Explanations:
1. Explain how thermal energy is transferred from the sun to Earth's surface.
"Thermal energy" refers to the<em> energy produced from heat</em>. The sun gives off <em>light energy</em> (solar) through it sunshine. This solar energy penetrates the atmosphere of the earth. Once the atmosphere is heated, it transfers the thermal energy to the Earth's surface in the form of rays. This process is called "radiation."
This can also be done through the process called "conduction." Since air is a poor conductor of heat, thermal energy is only being transferred in the atmosphere. Direct contact between objects is essential in conduction.
It is said that some of the heat transferred to Earth<em> bounces back to the atmosphere.</em> This is because once the Earth's surface heats up,<u> the </u><u>warmest air expands</u><u> and rises towards the atmosphere.</u>
2. How does this energy impact the land and water on Earth?
The sun heats up both the land and water on Earth. However, water is a good conductor of heat so it allows heat to stay in it for a<u> longer period of time. </u>On the contrary, the Earth's land surface is a poor conductor of heat so this allows heat to escape faster than in water. The rays of the sun can penetrate the water at a<em> deeper length</em> than that of the soil.
<h3>Exothermic reactions
</h3>
These are reactions that transfer energy to the surroundings (ie the energy exits from the reaction, hence the name exothermic). The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become hotter. A thermometer is used to detect the temperature increase.
Examples:
Combustion
Neutralisation between acids and alkali
<h3>Endothermic reactions
</h3>
These are reactions that take in energy from the surroundings (ie energy enters the reaction, which will help you to remember the name endothermic). The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become colder. A thermometer is used to detect the temperature decrease.
Example:
Electrolysis
Answer:
the answer is carrying oxygenated blood and nutrients to cells
