sos- power of the planet

Question 1

what is the landform cycle and what order does it go in

Answer 1

uplift
weathering
erosion
transportation
deposition
renewed

Question 2

what are the 3 forms of uplift

Answer 2

folding
volcanic
faulting

Question 3

what are the different types of volcanoes

Answer 3

calderas
scoria
shield
dome
strato

Question 4

how are volcanoes formed

Answer 4

formed by plate collision

Question 5

what is lava

Answer 5

molten rock that has reached the surface to burst or flow from volcanoes

Question 6

what is magma

Answer 6

molten rock inside the earth

Question 7

what is the difference between lava and magma

Answer 7

lava has reached the surface to burst or flow
magma is inside the earth

Question 8

what is viscosity

Answer 8

The thickness of a fluid, and its ability to flow eg. water (low viscosity) and honey (high viscosity)

Question 9

what is folding

Answer 9

Folding makes fold mountains
They are formed by the folding of rock layers, specifically when rock layers are squeezed together and pushed upward

Question 10

what are the 3 parts of folded mountains

Answer 10

anticline- The fold mountain
syncline- the valley
monocline- little hill (where there is only 1 fold) it goes flat

Question 11

what is faulting

Answer 11

where some parts of the earth are pushed upwards (therefore uplift) while others collapse down.

Question 12

what are the 2 types of faulting

Answer 12

• earthquakes
• mountains

Question 13

how are eathquakes cuased

Answer 13

by a sudden flip on a fault line

Question 14

how are fault- block mountains formed

Answer 14

by the movement of blocks when forces in the crust pulls it apart

Question 15

what is weathering

Answer 15

when rock is dissolved, worn away or broken down into smaller and smaller peices

Question 16

what are the two types of weathering

Answer 16

chemical and physical

Question 17

examples of chemical weathering

Answer 17

water, acids, gasses eg waitomo caves

Question 18

examples of physical weathering

Answer 18

wind, rain, thermal expansion and contraction

Question 19

what is erosion

Answer 19

wearing away of rocks and how wind, water and gravity carry away particles of rocks and soil broken down by weathering

Question 20

what are the different types of erosion

Answer 20

wind/ aeolian
rivers/fluvial
waves/coastal
ice/glacial

Question 21

what is wind/aeolian erosion

Answer 21

over hundreds of years wind blows away particles from the surface of rocks

Question 22

what is rivers/fluvial erosion

Answer 22

rain splashed onto rocks washes away particles and carries them into rivers

Question 23

what is ice/glacial erosion

Answer 23

a glacier is a mass of ice that flows down hill/ glaciers make u shape valleys

Question 24

what is transportation

Answer 24

as a river flow, the water sweeps along any loose soil, sand and rocks

Question 25

what is deposition

Answer 25

when moving water, ice or wind looses energy the material or sedements carried are then deposited. many landforms are the result
eg. plains or beaches
eg braided rivers/ in plains

Question 26

what is renewed/ renewal

Answer 26

to begin or take up again

Question 27

what is uplift

Answer 27

the process by which the earth slowly rises
