One part of science that is looked at in middle school is the coasts. Children will already understand that coasts are where the land and the sea meet, and now they will be taught about some of the geographic features that are found there, such as beaches, cliffs and bays.

Coasts are the edges of the land. The coast is the place where land and sea meet. There are special environmental features on the coast. Coasts are also places people meet for their holidays, where they can sunbathe on the beach, paddle in the sea and explore rockpools and caves.

See how much you know about coastal environments and the features that can be found there by playing this quiz.

Science: Middle School: Grades 6, 7 and 8 Quiz - Coasts (Answers)
1. On some coasts the cliffs are worn away by erosion. What acts on the cliffs to cause them to erode?
[ ] Pebbles
[ ] Sand
[x] Waves
[ ] Rocks
The waves can wear rock away, but it takes a very long time
2. What is the process called when waves throw pebbles at the cliff causing it to wear away?
[ ] Erosion
[x] Abrasion
[ ] Deposition
[ ] Transportation
Abrasion is faster than erosion
3. What is a large flat area of sand known as?
[ ] A cliff
[ ] A coast
[ ] A sand dune
[x] A beach
Beaches are places we go to enjoy the seaside
4. How are sand dunes formed?
[ ] The sea pushes the sand into hills
[x] The wind blows the sand into hills
[ ] They are man made
[ ] Rivers push the sand into hills
They are always at the back of the beach as the wind comes off of the sea
5. What is the term used when a cliff erodes at the bottom?
[x] Undercut
[ ] Abrasion
[ ] Deposition
[ ] Overcut
The higher part of the cliff is not exposed to the sea and so does not erode
6. When a bay is formed what is the name of the projections formed at either side?
[ ] Stacks
[ ] Arches
[x] Headlands
[ ] Caves
The bay is formed when the rock along part of the coast erodes quicker than the headlands as they have harder rock
7. When soft rock erodes to create a hole in the cliff what is this known as?
[ ] Stacks
[ ] Arches
[ ] Headlands
[x] Caves
Caves are deep depressions in the rock face
8. How is an arch formed?
[ ] When soft rock erodes and forms a hole in the cliff
[ ] When an arch erodes further, a part becomes separated from the coast
[x] When a cave erodes further and forms a tunnel through the cliff
[ ] When a rock is pushed by waves and becomes rounded
Arches are caves that have worn all the way through a cliff. They look almost man made
9. How is a stack formed?
[ ] When soft rock erodes and forms a hole in the cliff
[x] When an arch erodes further, a part becomes separated from the coast
[ ] When a cave erodes further and forms a tunnel through the cliff
[ ] When a rock is pushed by waves and becomes rounded
Stacks can seem very lonely!
10. What is the name of the protection used to stop sand being swept from a beach?
[ ] Sand dunes
[ ] Sea wall
[x] Groynes
[ ] Cliffs
Have you ever seen groins on a beach? They can look like pillars, posts or fences
