Question 4

Name 2 examples of igneous rock

granite and basalt

Question 5

how are sedimentary rocks made?

Answer 5

Rocks are weathered(broken up) then the erosion moves bits away, these are transported by ice water or wind(these bits are then called sediments), if the wind or water slows down its deposited or ice melted, then the minerals disslove in the water to make crystals which is what cement is for, compaction then squeezes the water out then finally more layers of sediment are deposited, this conpacts the sediments below

Question 6

how are igneous rocks formed?

Answer 6

they are made from through the cooling of magma(lava) when its hot molten rock rises to the surface it then changes temperature and pressure that cause it to cool, solidify and crystalize

Question 7

what are the differences between extrusive and intrusive igneous rock

Answer 7

extrusive- cools faster, so crystals are smaller

intrusive- cooled, formed slowly inside, so crystals are bigger

Question 8

which type of rock contains fossils?

Answer 8

sedimentary

Question 9

Which type of rock forms molten magma cools at the earth’s surface

Answer 9

igneous

Question 10

how are metmorphic rocks made?

Answer 10

by the heat but also pressure of existing igneous or sedimemtary material to a more denser form
