Exercises
1. Answer the following questions.
(i) Why do the plates move?
(ii) What are exogenic and endogenic forces?
(iii) What is erosion?
(iv) How are flood plains formed?
(v) What are sand dunes?
(vi) How are beaches formed?
(vii) What are ox bow lakes?
Answers
Answer:
Ans1-the heat from radioactive processes within the planet's interior causes the plates to move this movement is called plate motion or tectonic shift
Ans2-edogenic (or endogentic) factor are agent supplying energy for action which are located within the earth these factors are agents supplying energy for action that are located at the near of earth surface
Ans3-erosion is the action of surface processes that remove soil rock or dissolved material from one location on the earth crust and then transports it to another location
Ans4-when its flood it deposites a layer of fine soil rich mineral salts nutrients -rich silt sediment and distribute it across a wide area this formation is known as flood plain
Ans5-A dunes is a landform composed of wind or water driven sand it take the form of a mound,ridge or hills An area with dunes is a called a dune system or a dune complex
Ans6-beaches are wave deposited accumulation of sediment located at the shoreline they require a base to reside on usually the bedrock geology weaves to shape them sediment to form them and most are also affected by tides
Ans7-A curved lake formed from a horseshoe bend in a river where the main stream has cut across the narrow end and no longer flows around the loop of the bend
