Flashcards in Rivers-Upland and Water cycle Deck (33):
1

What are the 5 parts of the water cycle

Evaporation, condensation, precipitation, surface runoff, transpiration

2

What exactly happens during the water cycle part 1

The Sun heats up water and changes it to a gas (water vapor) by the process of evaporation, water that evaporates from earths oceans, lake, rivers, and moist soil rises up into the atmosphere. Evaporation also occurs from plants, it is called transpiration

3

What exactly happens in the water cycle part 2

As water vapor rises high into the atmosphere, it starts to cool and becomes a liquid again. This process is called condensation. When a large amount of water vapor condensed, it results in the formation of clouds

4

What exactly happens in the water cycle part 3

What the clouds get to much water the let the water fall back to earth. This is called precipitation it takes the form of rain, hail, sleet or snow

5

What is ground water

It is water that is absorbed into the ground

6

How does the groundwater get back to lakes?

It gets back using the ‘through flow’

7

What is surface runoff

Sure face runoff is when water can’t get absorbed into the ground so runs down hills until it gets to a lake

8

What is permeable and non permeable rock

Impermeable is when it can’t get absorbed into the ground
Permeable rock is when water can get absorbed into it until it is filled

9

What is infiltration

It is when water seeps into the ground

10

Where does a river start?

At the source in the upland areas of the mountains

11

What is a drainage basin

A drainage basin is an area drained by a river and its tributaries

12

What is a tributary

A tributary is a smaller river joining a larger one

13

What is the boundary of the drainage basin called?

Watershed

14

What is the place called when two rivers join together/meet

Confluence

15

What is abrasion

It is a type of erosion Sand and rock carried by the river

16

What is attrition

It is a type of erosion Stones and pebbles bouncing off each other and getting carried along by the river causing the load (rocks) erode

17

What is solution

It is a type of erosion Makes water acidic so some small materials dissolve in it

18

What is hydraulic action

It is a type of erosion. Fast flowing water forces it’s way into cracks causing the bank to expand

19

What happens when a river is faster and holds a lot of water?

It erodes more quickly

20

What are things that are carried by a river called?

Load

21

What is solution

Solution is a mode of transport. It is transparent and carries the lightest materials

22

What is saltation

Saltation is a mode of transport. It is sand grains bouncing along

23

What is suspension

Suspension is a mode of transport. It is the cloudy or muddy parts of soil in the river

24

What is bedload

Bedload is big heavy rocks carried along the bottom

25

What happens when a river looses energy

It starts to deposits rocks - starting with the heaviest

26

What is traction

Traction is a mode of transport. It means stones role along the ground

27

Which ones use up most to least energy starting with least and ending at most

Solution, Suspension, Saltation, Traction

28

Where is the lowest part of a river?

The mouth where it ends

29

What is a V shaped valley?

It is a steep narrow channel in between 2 hills

30

How is a waterfall formed?

It is formed when a river falls from harder rock to softer rock

31

What happens when the river starts to erode the soft rock underneath the hard rock

It creates a plunge pool

32

What is the hard rock called when there is no soft rock underneath it ?

An overhang

33

Eventually what will happen to the waterfall

It will make a gorge by the hard rock falling and it will retreat upstream
