England, Scotland, Wales and Northern Ireland

Question 2

Where is the UK?

Answer 2

It is in the north west of Europe, to the west of the UK is the Atlantic Ocean

Question 3

What is to the north of the equator?

Answer 3

the Tropic of Cancer

Question 4

What is to the south of the equator?

Answer 4

the Tropic of Capricorn

Question 5

What are the 7 continents?

Answer 5

Europe, Asia, North America, South America, Antarctica, Australasia, Africa

Question 6

What are the 5 oceans?

Answer 6

Sourthern, Indian, Pacific, Atlantic, Arctic

Question 7

What is erosion?

Answer 7

the removal of parts of the lands surface. It is caused by rivers, wind, water, and ice.

Question 8

What is hydraulic action?

Answer 8

the force of the water against the rock surface can cause air to be trapped in cracks. The pressure weakens the rock and gradually wears it away.

Question 9

What is abrasion?

Answer 9

stones and rocks are thrown at the rock surface. They scrape along a rock surface. The action is like sandpaper.

Question 10

What is attrition?

Answer 10

Rocks and stones knock together and wear each other away

Question 11

What is solution?

Answer 11

Water dissolves the surface of a rock.

Question 12

What is weathering?

Answer 12

the slow break down of rocks on the earths surface. it is caused by weather conditions such as rain or changes in temperature and sometimes plants and animals

Question 13

What is biological erosion

Answer 13

burrowing animals such as rabbits can burrow into a crack in a rock, making it bigger and splitting the rock. Plant roots can grow in cracks, opening the cracks in the rock

Question 14

What is chemical erosion?

Answer 14

rainwater is slightly acidic because carbon dioxide from the air dissolves in it. minerals in rocks may react with the rainwater, causing the rock to be weathered

Question 15

what is mechanical/ physical erosion?

Answer 15

water gets into a crack in a rock and then freezes; it expands and pushes the crack further apart. when the ice melts, water gets further into the crack. the processes repeats. this is called freeze-thaw weathering

Question 16

What are the three main groups rocks are classified into?

Answer 16

igneous rocks
sedimentary rocks
and metamorphic rocks

Question 17

What are igneous rocks?

Answer 17

igneous rocks (e.g. granite) are formed by magma from the molten inside part of the earth. when magma erupts it cools to form volcanic landforms.

Question 18

what are sedimentary rocks?

Answer 18

sedimentary rock (e.g. sandstone) are formed from sediments that have settled at the bottom of a lake, sea or ocean, and have been compressed over millions of years

Question 19

what is metamorphic rock?

Answer 19

metamorphic rock (e.g. slate) have been subjected to tremendous heat and/or pressure, causing them to change into another type of rock. they are usually resistant to weathering and erosion and are therefore very hard-wearing
