In Chapter 2, “Inside Our Earth,” we learned about the structure of the Earth. In Chapter 3, “Our Changing Earth,” we learn how the Earth’s surface is made up of big pieces called lithospheric plates. These plates move very slowly because of the molten magma inside the Earth. There are forces called endogenic forces that come from inside the Earth and exogenic forces that work on the surface. These movements cause very destructive earthquakes and volcanoes. This chapter helps us understand the dynamic nature of our planet.
Now lets solve 20 MCQ questions below. Later you can solve 10 fill in the blanks type of questions and answers too.
