How many of the key words can you identify? Complete your table… Key term Definition   The point where a river starts. It is usually at high altitude with low temperatures and plenty of precipitation. A small stream that joins a larger river. The point where two rivers meet. The point where a river meets the sea. The boundary of a river basin. A steep drop in the course of the river caused by an area of soft rock underlying an area of hard rock. This type of weathering occurs when water freezes in cracks in rocks and expands over night to widen the crack. The repetition of this process causes the rock to break up into smaller pieces. This type of weathering occurs when seeds fall into cracks in the rock and the roots of plants break the rock up. Burrowing animals can also be responsible for this type of weathering. This type of erosion occurs when sand and pebbles that are carried in the river wear away at the bed and banks. How many of the key words can you identify? Complete your table…

Now test each other on the key words….   This type of erosion occurs when chemicals in the river dissolve certain rock types, such as chalk and limestone. This type of erosion occurs from the sheer force of the water in the river crashing against the bed and banks. This type of erosion occurs when small pebbles and rocks collide within the river and become smaller and rounder. A sweeping bend in the course of a river. A large flat area either side of the river. This area tends to be very fertile. This type of engineering is usually expensive and involves major construction work to reduce the rate of erosion. This type of engineering is usually cheaper and works with the coastline to reduce the rate of erosion. A semi-circular area of water formed when a meander has cut through and taken a shorter route to the sea. Now test each other on the key words….
