I WONDER - How Are Lakes Formed?

The video explains how lakes are formed by glaciers and tectonic plate movements. Glaciers create basins that fill with water, while tectonic activity causes cracks that form basins. For lakes to persist, they require a constant influx of water to prevent evaporation.

How are some lakes formed by glaciers?

• By volcanic eruptions

• By glaciers scraping the ground and leaving basins

• By meteor impacts

• By human excavation

What happens to the basins left by glaciers?

• They remain empty

• They fill with water and become lakes

• They fill with lava

• They become deserts

How do tectonic plates contribute to lake formation?

• By causing cracks in the Earth's crust

• By generating earthquakes

• By forming valleys

• By creating mountains

What is necessary for a lake to avoid drying up?

• A deep basin

• A surrounding forest

• A high salt content

• A constant flow of new water

What will happen to a lake without a constant water supply?

• It will expand

• It will freeze

• It will become a river

• It will evaporate and dry up
