Rocks

What are the three types of rocks?

• Granite, marble, and sandstone

• Volcanic, limestone, and slate

• Igneous, sedimentary, and metamorphic

• Quartz, basalt, and shale

How are igneous rocks formed?

• From the cooling and solidification of magma or lava.

• From the compaction of organic waste.

• Because of the pressure and temperature inside the Earth.

• Through erosion and sedimentation of pre-existing materials.

What type of rock is formed from the solidification of magma?

• Igneous rocks

• Sedimentary rocks

• Metamorphic rocks

What is the main characteristic of metamorphic rocks?

• They are green.

• They are formed in the inner core.

• They are formed from the transformation of pre-existing rocks.

• They are formed by water evaporation.

What is the formation process of sedimentary rocks?

• Melting and solidification of minerals

• Erosion and sediment weathering

• Explosion and rock fragmentation

• Sediment accumulation and compress

What type of rock is formed from the accumulation and compaction of sediments?

• Metamorphic rocks

• Igneous rocks

• Sedimentary rocks

How are metamorphic rocks formed?

• By the action of sunlight on pre-existing rocks.

• By the action of heat and pressure on pre-existing rocks.

• By the action of micro-organisms on pre-existing rocks.

• By the action of wind and rain on pre-existing rocks.
