Which type of rocks are ceated by "heat and pressure"? a Minerals b Igneous Rocks c Sedimentary Rocks d Metamorphic Rocks

## Step 1<br />The question asks us to identify the type of rocks that are formed by the process of "heat and pressure". This process is known as metamorphism, which is a geological process that changes the physical or chemical constitution of rocks due to heat and pressure.<br /><br />## Step 2<br />Let's analyze each option:<br />- Minerals are naturally occurring substances with a definite chemical composition. They are not a type of rock, but rather the building blocks of rocks.<br />- Igneous rocks are formed from the cooling and solidification of magma or lava.<br />- Sedimentary rocks are formed from the accumulation of sediment, which is often deposited in layers and compressed over time.<br />- Metamorphic rocks are formed when existing rocks are subjected to high temperatures and pressures, causing physical or chemical change.<br /><br />## Step 3<br />Based on the above analysis, it is clear that the type of rocks formed by "heat and pressure" are Metamorphic Rocks.
