Transpiration
___________ can be rain, hail, sleet or snow
Precipitation
_______ is water moving across the ground as a stream or river
Runoff
___________ is water moving downwards through the soil, into the rocks below
Percolation
___________ is water being stored in porous rocks deep below the ground
Groundwater
Surface _______ is when water lies on the ground as puddles or lakes
Storage
Groundwater ____ is very slow water movement deep below the ground
Flow
___________ is when surface water soaks into the soil
Infiltration
____________ is when water droplets collect on trees and plants
Interception
_________ is water flowing downhill through the soil
Throughflow

Table
A _______ _____ is an area of land that is drained by a river and its tributaries
Drainage Basin

Decreases
A river also has a _______ profile
Concave
The _____ course has V-Shaped valleys which are caused by vertical erosion
Upper
In the middle course of a river, __________ is the main transportation type
Suspension
The River ______ is the land surrounding the river
Valley
The River ______ is the part of the river that holds the water
Channel
________ is the wearing away and removal of material by a moving force
Erosion
_________ Action is a type of erosion where the force of the water and air hit the bed of the banks of the river
Hydraulic
________ is a type of erosion where material scrapes at the bed and banks of a river to erode
Abrasion
_________ is a type of erosion where material bounces/hits other material, making it smoother and rounder.
Attrition
_________ is a type of erosion where chemical reactions take place which dissolves rock as the river flows over (often limestone or chalk)
Solution

Lateral
____ is any sediment that is carried in the flow of a river
Load
___ load is material being transported along the bed of a river
Bed

Suspended
_______ is the speed at which the river flows
Velocity
Gradient and _____ of water impact velocity
Volume
