Year 7: The Jurassic Coast Quiz

In which two counties is the Jurassic coast found?

• Devon

• Cornwall

• Dorset

• Durham

What type of rock makes up the Jurassic coast?

• Igneous

• Sedimentary

• Metamorphic

What is the primary feature of the Jurassic coast?

• Volcanoes

• Fossil-rich cliffs

• Deserts

The rock dates back to the Jurassic and which other two periods

• Tertiary

• Cretaceous

• Triassic

• Quaternary

Match the rock type to how it is formed.

• Formed by sediments building layers

• Metamorphic

• Formed from existing rock types under high pressure and temperature

• Sedimentary

• Formed from cooled and hardened lava

• Igenous

What does the term more resistant mean?

• Rock is easier to erode

• Rock will never erode

• Rock is harder to erode

• The rock has been completely eroded

Which are the two types of erosion responsible for breaking down rock at the coast?

• Traction

• Suspension

• Abrasion

• Hydraulic action

Reorder the following to show how sedimentary rock is formed.

• The weight of the layers and water compact, or squash, the sediments together.

• Rivers then deposit the sediments into larger bodies of water (seas / oceans) where they form in layers.

• These sediments then carried by rivers.

• Dissolved minerals in the water cement, or glue, the sediments together.

• Rocks are weathered / broken down into smaller pieces called sediments.

What is a common characteristic of sedimentary rocks?

• They have a glassy texture

• They contain fossils

• They are formed from magma

• They are highly resistant to erosion

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

• Granite

• Marble

• Limestone

• Basalt
