. Because Susan’s diagram is showing that the half of the Moon that is facing the sun is lit by the sun, and the other half is dark
Explanation:
We can see on the diagram on the left side arrows that show the way from which sunlight appears.<u> It only lights up the left side of the sun, while the right one stays dark.</u>
<u>The moon does not produce any light or energy on its own, so only the side that is facing the Sun at the moment is lit up. </u>That is also the only side we can see from the Earth.
Because of the way and pace Earth and moon move through space and around their own axis, we can only constantly see only one side of the moon. The other side always stays dark, and it is often called the “far side of the moon”.
The position of the sun and moon also determine the phases of the moon we see from the Earth. If more of the moon is visible, that means the moon is positioned to directly face the sun and be lit up. If we don’t see much, the sun lights up only that portion of the moon.
Answer:
the last picture
Explanation:
The picture that shows the position of Earth during summer in South Carolina would be the last picture, I highlighted it in red below. South Carolina is located in North America. Summer is the hottest time of the year because it is when your location is closest to the sun. Which in the pictures provided the only one in which North America is closest to the sun is the last picture. Also the earth rotates on an inclined axis so pictures 2 and 3 would not be valid.
The correct answer is - cyanobacteria.
The atmospheric oxygen came from the cyanobacteria. These were one of the earliest living organisms on Earth. The cyanobacteria was using photosynthesis in order to create its own food. The photosynthesis process requires sunlight, carbon dioxide, water, and oxygen. The oxygen is mostly released as a waste product from the process of photosynthesis, thus the cyanobacteria were literally releasing oxygen that was ending up into the atmosphere. As more and more cyanobacteria there were across the planet, more and more oxygen they were releasing into the atmosphere, slowly changing the composition of the atmosphere, and setting the basis of it as we know it now.
I think the answer is B.
