The correct answer is - D. Composite.
The rocks are divided into three basic groups, igneous rocks, sedimentary rocks, and metamorphic rocks, with later classifications taking place into those three groups.
The igneous rocks are the newest rocks. They form from the cooling magma, and they are the basis for the evolution of the other two types of rocks. These rocks are also the strongest.
The sedimentary rocks form after millions of years of erosion of the igneous rocks, and then the eroded parts are getting stuck together with high temperatures, pressures, or natural agents that act like glue.
The metamorphic rocks are rocks that are forming deep into the ground, and they come to be after one of the other two rock types undergoes high temperatures and pressures for prolonged period of time underground.
Explanation:
The processes used by these actions are known as Weathering and Erosion.
Rainfall (water from the cloud) falls carrying out two major actions, firstly, it dissolves chemicals in the atmosphere and this solution causes chemical reactions on the various surfaces it falls on thereby weakening those surfaces through this action and secondly, by its impact on it wears off the surface. This second action becomes more vivid when you study the impact of a drop of water on a sandy surface. The impact dislodges the soils particles from others.
When there is significant amount of rainfall it leads to runoff (water running on the surface) and this runoff has enough force to move loose soil and rick particles to be deposited at a new location. The movement of these particles causes wear and tear on the surface on which they are moved and over time a new landscape evolves.
Water in the form of ice also causes significant landform changes especially in the temperate regions. This occurs through a process called ice or frost wedging. This essentially means water lodging in cracks and crags of rock get frozen and since frozen water expands it forces the crack to become wider and often times dislodging part of the rock surface.

The correct answer is - physical geography.
The focus of the physical geography is on the physical features on our planet, be it bodies of water, landforms, or natural resources. The physical geography is interested in the shape of the natural physical features, as well as their structure, how did they become like that, the evolution trends, what was the cause for them to form, and how will it all look like in the future. It is a very wide geographic area of study, and it has lots of sub-disciplines as part of it, in order for every specific aspect of the nature to be properly examined and explained.
