Rock Cycle quiz

What is a rock?

• A solid collection of one or more different grain-sized minerals and crystals

• A mixture of molten lava and ash

• A layer of sedimentary material

• A combination of heat and pressure

What is the rock cycle?

• A cycle of rock formation and destruction

• A continuous process of transforming rocks from one type to another

• A pattern of rock formation and erosion

• A process of melting and cooling rocks

What are the three types of rocks?

• Igneous, sedimentary, and metamorphic

• Granite, diamond, and quartz

• Magma, pumice, and ash

• Sandstone, shale, and limestone

How are igneous rocks formed?

• From the accumulation and lithification of sediments and organic material

• By the evaporation or precipitation of mineral-rich water

• By intense heat and pressure causing existing rocks to transform

• From molten lava that has cooled either within the Earth's crust or on the surface

What are clastic sedimentary rocks?

• Rocks formed from the accumulation and lithification of sediments and organic material

• Rocks composed of minerals that precipitated from evaporating sea water

• Rocks that have been changed by intense heat and pressure

• Rocks formed from compressed pieces of rocks

What are organic sedimentary rocks composed of?

• Dead plants and animals buried under layers of sediments

• Silica that precipitated from water

• Calcite

• Rocks that are composed of minerals that precipitated from evaporating sea water

What is limestone?

• A hard, glassy sedimentary rock composed of silica

• A chemical sedimentary rock composed mostly of calcite

• A type of clastic sedimentary rock

• A metamorphic rock

What is the most common type of metamorphic rock?

• Slate

• Marble

• Schist

• Quartzite

What causes the banded or foliated appearance of many metamorphic rocks?

• The accumulation and lithification of sediments and organic material

• The recrystallization of minerals within the rock

• The evaporation or precipitation of mineral-rich water

• The formation of dead plants and animals buried under layers of sediments

What can geologists learn by studying metamorphic rocks?

• The processes that caused the rock to change

• The type of rock it was originally formed from

• The amount of pressure and temperature the rock was subjected to

• D) All of the above
