Explain about igneous,metamorphic, sedimentary rocks draw a diagram of rock cycle and explain rock cycle
Answers
Explanation:
Igneous — they form from the cooling of magma deep inside the earth. ... Metamorphic — they are formed through the change (metamorphosis) of igneous and sedimentary rocks. They can form both underground and at the surface. Sedimentary — they are formed through the solidification of sediment.
The process of transformation of rocks from one form to the other in a cyclic manner is known as the rock cycle. It includes the following processes: Hot lava cools down to form igneous rocks. Igneous rocks are then broken down into small particles which are transported and then deposited.
Answer:-
There are 3 different types of rocks; igneous, sedimentary and metamorphic.
Igneous rock is formed when magma or lava from volcanoes cools. Examples include basalt and granite. Most igneous rock is very hard. Some of the most spectacular rock formations on our planet are made of igneous rock; in Britain we see granite shapes called tors in south-western locations like Bodmin Moor, Dartmoor and Land's End.
Sedimentary rocks are formed over millions of years when sediments (tiny pieces of rocks and animal skeletons) are pressed together at the bottom of seas and rivers. Examples include sandstone, coal and chalk. Some sedimentary rocks contain fossils (bones or shells of living things that were buried long ago and have turned to stone).
Metamorphic rocks are formed when other rocks are changed due to heat or pressure. Examples include slate and marble. Metamorphic rocks are very hard but can be damaged by acids like acid rain (on buildings) or even lemon juice (on worktops!).
