Front 1

a rock is a

Back 1

mixture

Front 2

the rock cycle suggests that

Back 2

rocks ae continually recycled into different forms

Front 3

what does the term rock removal mean?

Back 3

Rocks may be carried away by the wind or water, but it is never lost.

Front 4

how are igneous rocks formed

Back 4

they are formed by colled magma

Front 5

why does magma rise to the surface

Back 5

because magma is less dense than the surrounding rock

Front 6

Intrusive rocks

Back 6

have large mineral grains and are formed beneath Earth's surface

Front 7

Extrusive rocks

Back 7

have small minerals grains and are formed on the top of Earth's surface

Front 8

Igneous rocks can be

Back 8

intrusive or extrusive

Front 9

why are basaltic rocks dark?

Back 9

because they contain large amounts of iron and magnesium

Front 10

Granitic rocks are

Back 10

igneous rocks, light colored and have a high concentration of silica

Front 11

what are the characteristics of Andesitic rocks?

Back 11

they have mineral compositions between granitic and basaltic rocks
