Question

give reasons. 1 we cannot go to the centre of the earth 2 sedimentary rocks are formed from sediments. 3 limestone is changed into marble.​

Answer 1

Answer:

1. we can't go in center of earth becz temperature and pressure increases enormously.
2. sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.
3. Marble is a metamorphic rock formed by the alteration of limestone by heat and pressure

Answer 2

1. We can’t reach the centre of the earth as it is extremely deep and unreachable, it would cost a lot and consume time and resources which we don’t have access to. The centre of the earth is extremely hot and pressurised as well.
2. Sedimentary rocks take millions of years to form. They are formed under intense pressure. Sedimentary rocks contain sediments and are formed from dead plants and animals or minerals from millions of years ago.
3. Marble is a metamorphic rock which is formed from limestone under intense pressure and heat. But remember that marble is a metamorphic rock and limestone is a sedimentary rock
