Question

explain why there has been change over the earths surface

Answer 1

There are basically 2 types of changes that occur to the earth’s surface (i) Slow change and (ii) fast change. Fast changes occur through the actions of Earthquakes, volcanoes, landslides, etc. while slow change takes time and has a process. The focus of this discuss is the slow change since its action is carried out on all parts of the earth’s surface.

There are two main causes of change to be mentioned here and they are water action and wind action. 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.

Answer 2

The surface of the earth changes.Some changes are due to slow processes such as erosion and weathering and some changes are due to rapid processes
