the earth's surface changes slowly but
Answers
Answer:
In contrast, much of Earth's surface is changing slowly. During slow changes, landforms made of rocks can be broken down into smaller pieces of rocks in a process called weathering. ... Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind, or gravity.

Answer: The Earth’s surface is constantly changing. These changes mostly occur in very minute ways which over time accumulates to create the earth’s physical features we observe around us today. Some of these changes take thousands of years but surely they are occurring. When you look around you a mountain, river, plateau, valleys, rock boulders, etc. these all didn’t just appear suddenly rather most of them had a building process like building a house.
But how and what causes these changes to the earth’s surface?
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.
