The answer is; B is younger than D


In sedimentary rocks, the bottom layers are older that overlaying layers. This is because sediments are placed on top of each other by surface runoffs to ocean beds. Therefore, the first sediments to be deposited will always be towards the bottom as more and newer ones are brought in and deposited.

Which surface erosion event does the most short- term damage?
kipiarov [429]

Answer:

Occurrence of mud slides after heavy rains.

Explanation:

Soil erosion is defined as the removal of top soil from the land and it affects the fertility of the soil. It is also known as soil degradation.

Soil erosion has both short-term and long-term damage. Short-term damage of erosion includes the occurrence of mudslides after heavy rains which is called landslide. It is a short-term damage because landslides took long-duration to happen and when happened it can be shortly recovered using machines.

Hence, the correct answer is "the Occurrence of mudslides after heavy rains."
