BJU Press Earth Science Chapter 10

An old earth idea that rock is recycled just like nearly every other natural resource

When limestone undergoes metamorphosis, it becomes __________.

Length of time is not an important component of metamorphism

Most rocks are made of two or more minerals.

A rock made from the eroded pieces of other rocks

The classification and identification of rocks is called mineralogy.

A __________ is a scientist who studies the classification and origin of all types of rocks.

The last step in forming a sedimentary rock would be _________________

Metamorphism that occurred over large geographical areas

A rock formed from volcanoes (magma or lava)

Sedimentary rock formed from chemical precipitation or deposition of fossils

Many creation scientists think that the basement rocks (bottoms of the continents) were probably __________.

Metamorphism caused by direct contact with a magma intrusion (sill or dike)

Which of the following does not belong with the other three?

What are two properties that help classify metamorphic rocks?

Which kind of sedimentary rock is most useful as a construction material?

Old-earth geologists believe that it took millions of years for layers of sedimentary rocks to form.

About how old are the oldest sedimentary rocks according to the Young Earth view?

Rocks formed strictly from minerals precipitated (turned back to solid) from water are __________.

A clast is a fragment of rock or other material cemented into a rock.

Which of these steps would come between deposition and cementation in the forming of a sedimentary rock?

Larger igneous mineral crystals mean that the rock cooled more slowly and probably formed deeper in the earth.

metamorphic rock containing flattened mineral crystals, giving it a banded or layered appearance

The individual rock particles or pieces that give a rock its texture are known as

The grain size of a rock like pumice is _______.

__________ rocks are formed when molten rock cools and hardens.

Cementation is what turns clastic sediments into sedimentary rock.

A _________ ________ is a hot water solution that can also cause metamorphosis to occur.

A rock made of sediments produced by erosion or chemical precipitation

The solid material in earth’s crust that is a combination of minerals or other materials

What physical law assures us that the amount of material in the earth doesn’t change?

A rock that has changed due to heat or pressure

How a rock looks and feels based on the sizes of the grains and other particles that make it up

___________ rocks are formed from bits and pieces of eroded rocks.

A rock made almost entirely of fossil shells loosely cemented together

_____________ involves water carrying particles from one place to another.

Concrete is composed mainly of igneous rocks like granite.
