The Law of Superposition

Front

Based on the law of superposition, what is the order of these rock layers, from oldest to youngest? Options: 1, 2, 3, 4; 2, 1, 4, 3; 3, 2, 1, 4; 4, 3, 2, 1

Back

4, 3, 2, 1

Front

These rocks are often foliated, meaning they have layers.

Metamorphic

Front

As a result of cooling slowly, these rocks develop air pockets and are often very lightweight. What type of rock is this? Options: Sedimentary, Metamorphic, Intrusive Igneous, Extrusive Igneous

Back

Intrusive Igneous

Front

Formed by heat and pressure

Back

Metamorphic

Front

Formed by cooling & solidification of magma
