Geography: Raging Rivers?
Key Vocabulary: | |
Water cycle | This is the cycle where water evaporated into water vapour. The water vapour rises from the land to the sky. It then condenses in clouds as it cools and falls as rain. |
Upper Course | This is the beginning of a river, starting with the source. It is usually located high up in the hills or mountains. |
Middle Course | This is the middle part of the river which often meanders over flatter land. |
Lower course | This is the end of the river. The river is usually bigger and more full of water at this stage. It will end by flowing into another river or the sea. |
source | Where a river begins |
meander | A bend in a river caused by erosion, typically found in the middle course of a river where the ground is less steep. |
Key Vocabulary: | |
mouth | where a river flows into the sea |
tributary | a smaller river that joins a bigger river |
water fall | where water falls off hard rock onto softer rock |
erosion | where water or wind wears away rock or soil |
deposition | where water slows and drops the rocks it has eroded |
valley | a channel between mountains or hills that a river flows down |
delta | a river mouth where sediment has been deposited |
sediment | the rocks and soils that are deposited after erosion |
confluence | where two streams or rivers join |
