<span>Scientists record the size and number of impact craters and how eroded they are to determine the ages and histories of different planetary surfaces.Older surfaces have been exposed to impacting bodies (meteoroids, asteroids, and comets) for a longer period of time than younger surfaces. Therefore, older surfaces have more impact craters. </span>
Answer:
B
Explanation:
The rising water level is mostly due to a combination of melt water from glaciers and ice sheets and thermal expansion of seawater as it warms.

If the Earth's rotation axis were tilted by 45 degrees instead of 23.5 degrees, then the seasons would be more extreme.
<h3>What is the rotation axis of Earth?</h3>
The rotation axis of the Earth is an imaginary straight line around which the Earth spins. It goes from the North Pole to the South Pole cutting through the center of the Earth. The axial tilt of the Earth which is also known as the obliquity of the ecliptic is about 23.5 degrees. Due to this tilt, the Sun shines on different latitudes and longitudes at different angles throughout the year. This is why we have different seasons. Uranus has the largest axial tilt in the solar system, which is around 98 degrees.
If the Earth's rotation axis were tilted by 45 degrees instead of 23.5 degrees, then the seasons would be more extreme as the rays of the Sun would fall directly in the summer and not so direct in the winter.
