WED, Ground/Surface Water/Succession/Catastrophic Events

Why would sand dunes MOST LIKELY form?

• a landslide depositing the sand near the back making dunes.

• A river that flowed through the beach area, carving out the dunes.

• the deposition of sand carried by swift wind blowing along the coast.

• tectonic plates beneath the beach moving the sand upwards.

If bare soil (all plants and trees have been removed) is exposed after a natural disaster, this could lead to increased-

• soil erosion

• insect populations

• water retention

Climax community and equilibrium are related in that when a community reaches climax, it is in equilibrium.

• soil, rock, larger plants, smaller plants

• rock, soil, lichens/mosses, grasses, larger shrubs, trees

• soil, rock, grasses, lichens/mosses, larger shrubs, trees

Which of the following is the correct order that secondary succession of producers would occur?

• soil, rock, small plants, larger plants

• soil, rock, larger plants, smaller plants

• rock, soil, lichens/mosses, grasses/flowers, larger shrubs, trees

• soil, grasses/flowers, larger shrubs, trees

What could have caused this geographical phenomena to occur?

• windstorms that weather the rock and carry it away

• weathering and erosion over a long period of time caused by a fast moving river

• tectonic plates causing uplift of the land

• chemical weathering due to acid rainfall
