Types of Rocks Quiz

What are the three main types of rocks?

• Granite, Basalt, Limestone, Sandstone

• Igneous, Sedimentary, Metamorphic, Volcanic

• Igneous, Sedimentary, Metamorphic, Volcanic

• Marble, Obsidian, Pumice, Andesite

How are igneous rocks formed?

• By cooling and solidifying magma

• By heat and pressure underground

• By compacting small rock pieces and sand

• By the process of sedimentation

What are the two main types of igneous rocks?

• Limestone and Sandstone

• Granite and Basalt

• Marble and Obsidian

• Pumice and Andesite

How are sedimentary rocks formed?

• By heat and pressure underground

• By cooling and solidifying magma

• By compacting small rock pieces and sand

• By the process of sedimentation

What do most sedimentary rocks contain?

• Volcanic eruptions

• Large crystals

• Trapped gas bubbles

• Layers of other rock fragments

What causes the formation of metamorphic rocks?

• Heat and pressure underground

• Erosion and weathering

• Cooling and solidifying magma

• The process of sedimentation

What is the meaning of the term 'metamorphic'?

• Changed in form

• Formed by the process of sedimentation

• Formed by volcanic eruptions

• Formed by cooling and solidifying magma

Which of the following is an example of a metamorphic rock?

• Creta

• Arenisca

• Mármol

• Obsidiana

What are the characteristics of metamorphic rocks?

• Have layers and shiny crystals

• Formed from lava cooling rapidly

• Contain trapped gas bubbles

• Dense and dark in color

What is the main difference between intrusive and extrusive igneous rocks?

• Intrusive rocks are dense and dark, while extrusive rocks are light and granular

• Intrusive rocks are formed by heat and pressure, while extrusive rocks are formed by erosion

• Intrusive rocks form underground, while extrusive rocks form on the surface

• Intrusive rocks form from sedimentation, while extrusive rocks form from magma cooling
