Types of rocks

​

​Sedimentary Rock

​

​includes:-

​chalk

​sandstone

​

​

​Properties of sedimentary rock

• ​Crumbly

• Made from grains

• ​Soft

​

• ​porous.

​

They have gaps between the grains so air or water can get into the gaps

​

​

​Not porous

​

​

​

Multiple Choice

An igneous rock commonly used as building material is

• Slate

• Sandstone

• Granite

Multiple Choice

A type of rock that forms from the cooling of molten rock at or below the surface of the earth

• Igneous Rock
• Metamorphic Rock
• Sedimentary Rock
• chemical Rock

Multiple Choice

The process by which igneous rocks are formed...

• heat and pressure deep underneath earth's surface
• melting and cooling of magma
• compaction and cementation of sediments

Multiple Choice

Which type of rock is formed from the solidification of magma or lava?

• igneous

• sedimentary

• metamorphic

Multiple Choice

Where is magma located?

• above ground

• below ground

Multiple Choice

Where is lava located?

• above ground

• below ground

• in the core

• in the mantle

​Metamorphic rock

​Metamorphic rocks form over millions of years when heat, high pressure change an existing rock.

​

​Marble starts out as limestone. Marble forms when limestone below the Earth's surface heats up. The limestone does not melt, but its particles are rearranged.

​Slate formed from mudstone
