River Tees Geography Quiz

Lateral erosion is when a river erodes sideways instead of downwards, widening the river valley.

Ox-bow lakes are formed when meanders in a river get cut off, creating a curved lake.

Flooding becomes disastrous because the water cannot flow back into the river due to the elevated river bed.

Meanders are formed due to erosion on the outside bend of the river and deposition on the inside bend.

Levées are high banks of silt along the river banks formed by slow-flowing rivers during floods.

The river in the upper course flows over hard, impermeable rocks, has steep sides forming a V-shape valley, and is turbulent and clear.

The confluence of tributaries widens and deepens the river downstream as they join, impacting the flow and volume of the river.

High Force waterfall and gorge were formed over millions of years due to erosion of softer rocks below harder rocks, leading to the collapse of the hard cap rock and retreat of the waterfall upstream.

In the upper course, the river channel is shallow and rocky, while in the lower course it becomes wider and deeper due to the accumulation of sediments.

The presence of harder cap rock over softer rocks like limestone, sandstone, and shale, along with the force of water erosion, contribute to the formation of waterfalls like High Force.
