Answer:Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth's plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and Antarctica.
Explanation:
Answer:
When population is increases then consumption of all resources will also increases.When population is more then they need more area for making house,for agriculture ,for industries and many more.And we know 31 % are present in the earth surface.So more making the land for sustainable use ,the human population are cutting the trees and this is know as deforestation.
Due to deforestation lots of natural resources are going slowly slowly disappear and making the life of human difficult day on day.
Causes of deforestation:
1.More population
2.Mining
3.Floods
4.Forest fires
5.Logging
6.Agriculture expansion
Answer:
The ratio will be 1:400,000.
Explanation:
An original map of scale 1 ratio 200,000 is enlarge twice then the ratio will be 1 : 400,000. Due to twice the ratio we can see the map more clearly as compared to the previous one. Due to twice enlargement of the map, we collect more information about the places we study and we can see many very object on the map which can't be seen earlier when the ratio is 1: 200,000 so we can say that twice enlargement makes the map more visible.
I think the correct answer from the choices listed above is option C. The theory of punctuated equilibrium portrays evolutionary change as a smooth curve. In this theory, species are said to be stable changing little for millions of years. Hope this answers the question.
