Water Cycle Flashcards
What is evaporation?
This is the process in which liquid water is changed into water vapor, which is a gas
What is condensation?
This is the process by which water vapor changes into water droplets
What is precipitation?
This occurs when water in any of its forms falls from the atmosphere to the surface
What is water cycle?
This is the continuous movement of water between the earths surface and atmosphere in its various state
What is transpiration?
This is when water vapor is taken from plants.
What are the other processes in the water cycle?
Surface runoff
Groundwater
Through flow
Infiltration
Peredation
Interception
Stem flow
3 functions of a River
Erosion,transportation and deposition
2 reasons why a river deposits its load
Either because the River slows down or the amount of water in the river channel decreases
Which function of the River js most common in the water course
Transportation
Which river feature is associated with slip off slope and river cliff
River meanders
Process where water evaporates from trees
Transpiration
Ways in which waves transport their load
Traction
Saltation
Solution
What is longshore drift
the movement of sediments along a coast by waves that approach at an angle to the shore
Describe three differences between constructive and destructive waves
Destructive waves have stronger backwashes than swashes, it is more larger and powerful and normally forms when there is a storm
Constructive waves are made when the sea is calm and they deposit materials onto the shore
Describe the formation of one coastal erosional feature
Abrasion is a process that creates coastal erosion landforms through the movement of rock in waves crashing against rock faces.
Describe the formation of one coastal depositional feature
Longshore drift is the main way that sediment is moved and deposited along a coastline
4 types of erosion in rivers
Corrosion
Hydraulic
Abrasion
Attrition
How does deposition take place in rivers
When the River loses energy
Wave crest
The highest part of the wave
Wave trough
The lowest part of the wave
Wave height
The vertical distance between the wave trough and the wave crest
Wave length
The distance between two consecutive wave crests or between two consecutive wave troughs.
Corrasion/ abrasion
: As the river flows it grinds its load against its bed and banks. This loosens material which the river carries downstream.
Attrition
This refers to the process by which material being carried by the river, such as rocks and stones, collide with each other.
Saltation
Particles such as small stones are bounced along the riverbed as they make their way downstream.
Traction
The heaviest material in the river’s load, such as large rocks, are simply rolled along the riverbed.
Surface runoff
precipitation that runs off the landscape.
Erosion
the process where rocks are broken down by natural forces such as wind or water
Deposition
the laying down of sediment carried by wind, flowing water, the sea or ice
What is weather
the state of the air and atmosphere at a particular time and place
Climate
Climate is the long-term pattern of weather in a particular area.
What is solution
Dissolve chemicals transported
Suspension
Lighter particles can be picked up and carried within the water
Source of a river
This is where the river begins
There are three types of erosion:
Headward
Lateral-widening
Vertical-deepening
Hydraulic action
The sheer force of water on rocks
