Flashcards in Rivers-Upland and Water cycle Deck (33):
What are the 5 parts of the water cycle
Evaporation, condensation, precipitation, surface runoff, transpiration
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
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
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
What is ground water
It is water that is absorbed into the ground
How does the groundwater get back to lakes?
It gets back using the ‘through flow’
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
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
What is infiltration
It is when water seeps into the ground
Where does a river start?
At the source in the upland areas of the mountains
What is a drainage basin
A drainage basin is an area drained by a river and its tributaries
What is a tributary
A tributary is a smaller river joining a larger one
What is the boundary of the drainage basin called?
What is the place called when two rivers join together/meet
What is abrasion
It is a type of erosion Sand and rock carried by the river
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
What is solution
It is a type of erosion Makes water acidic so some small materials dissolve in it
What is hydraulic action
It is a type of erosion. Fast flowing water forces it’s way into cracks causing the bank to expand
What happens when a river is faster and holds a lot of water?
It erodes more quickly
What are things that are carried by a river called?
What is solution
Solution is a mode of transport. It is transparent and carries the lightest materials
What is saltation
Saltation is a mode of transport. It is sand grains bouncing along
What is suspension
Suspension is a mode of transport. It is the cloudy or muddy parts of soil in the river
What is bedload
Bedload is big heavy rocks carried along the bottom
What happens when a river looses energy
It starts to deposits rocks - starting with the heaviest
What is traction
Traction is a mode of transport. It means stones role along the ground
Which ones use up most to least energy starting with least and ending at most
Solution, Suspension, Saltation, Traction
Where is the lowest part of a river?
The mouth where it ends
What is a V shaped valley?
It is a steep narrow channel in between 2 hills
How is a waterfall formed?
It is formed when a river falls from harder rock to softer rock
What happens when the river starts to erode the soft rock underneath the hard rock
It creates a plunge pool
What is the hard rock called when there is no soft rock underneath it ?
