Multiple Choice

Geologists have classified rocks into three major groups of rocks which are:

• inorganic, organic and chemical rocks

• igneous, sedimentary and metamorphic rocks

• metamorphic, chemical and non chemical rocks

• sedimentary, inorganic and igneous rocks

Multiple Choice

What is the MAIN way rocks are classified?

• Their color and shapes
• How they form
• Mineral bands
• Where they form

Multiple Choice

What can cause rocks to change?

• The Earth's orbit around the sun

• Environmental conditions

• The minerals falling apart

• Internal conditions

Multiple Choice

The rocks cycle follows a specific order?

• True

• False

Multiple Choice

Which statement is the best description of what

happens in the rock cycle?

• Rocks on old mountains are gradually weathered away, while mountain building and volcanism form new mountains.

• Once formed, rocks stay in place until rocks above them are weathered away and they reach the surface.

• As sedimentary rocks are buried deep below other rocks, they are changed by heat and pressure, eventually return to the surface, and are weathered again.

• Younger sedimentary rocks are always deposited on top of older metamorphic or igneous rocks.

Multiple Choice
