Leonard Santiago · Answer 1

b. Metamorphic rocks.

Explanation:

Metamorphic rocks are those that were once igneous or sedimentary rocks, but that were changed due to intense heat or pressure. This process of change is called metamorphism. The change causes these rocks profound physical or chemical change. There are many different types of processes that can lead to metamorphic rocks, such as simply being deep beneath the Earth's surface or continental collisions.

Van Barber · Answer 2

Answer: B. Metamorphic rocks

Explanation: Metamorphic rocks are those that have undergone changes due to extreme heat and pressure. Thus, the rock, from which it becomes a metamorphic rock, is heated at temperatures above 150-200 ° and exposed to a pressure of 1500 bar. In this way, the structure of the rock is changed, in terms of the arrangement of the atoms, and the result is a change of physical and chemical properties. There are two basic types of metamorphic rocks: foliated and slate. Generally, some of the metamorphic rocks are anthracite, schist, quartzite, marble, etc.
