Answer:
Rocks change from one type to another in a specific order.
Explanation:
A rock cycle can be described as a process that follows a sequence or a specific order in which the various rocks are transformed from one type to another. We have three types of rock: Igneous, Sedimentary and Metamorphic rocks.
In a rock cycle, rocks change from one type to another in a specific order which are:
Weathering →Transportation→ Deposition → Compaction and Cementation → Metamorphism → Rock melting
1) Weathering
This process starts from the Igneous rocks that are found on the Earth's Surface. These rocks are worn away and subjected to weathering by agents of weathering such as Wind or Rain and reduce them into to smaller particles.
2) Transportation
The smaller rock particles are transported by wind or by rain, rivers e.t.c.
3) Deposition.
These rock particles are deposited in certain areas and they begin to form layers of sediment.
4) Compaction & Cementation.
As the layers of sediment begin to form and take shape, the weight and pressure of these sediments over each other results in them solidifying or becoming more compacts starting from the layers at the bottom.
These sediments consisted of dissolved minerals which fill in the small gaps between particles and solidify them. THIS PROCESS RESULTS IN THE FORMATION OF SEDIMENTARY ROCK.
5) Metamorphism.
Sedimentary rocks can be found underground and while they are underground, these rocks are exposed to a very high temperature and pressure, which changes them into METAMORPHIC ROCK.
6) Rock Melting.
Metamorphic rocks underground melt to become magma. As the molten magma cools down on the Earth's surface it becomes hard, solidifies and becomes igneous rock. And the rock cycle continues again.
