Geography MCQs

Afforestation creates new tree cover on nonforest land.
It may support carbon storage, soil protection, and habitat.

Migration may be internal or international, temporary or permanent.
It changes population distribution.

Convergent boundaries involve collision or subduction.
They can produce mountains, trenches, earthquakes, and volcanoes.

Weathering breaks rock without necessarily moving the material.
It may be physical, chemical, or biological.

Precipitation includes rain, snow, sleet, and hail.
It occurs when cloud particles grow heavy enough to fall.

At night the land becomes cooler and higher pressure develops over it.
Air flows toward the relatively warmer sea.

Transform plates move sideways relative to one another.
This motion commonly produces shallow earthquakes.

Erosion moves sediment through water, wind, ice, or gravity.
It differs from weathering, which occurs in place.

Air rises over high terrain, cools, and condenses.
The windward side commonly receives more rainfall.

Air pressure falls with altitude, allowing rising air to expand and cool.
Mountain climates are therefore cooler than nearby lowlands.

A denser plate descends into the mantle at a convergent margin.
Subduction creates trenches and volcanic arcs.

Nitrogen forms about 78% of the atmosphere.
Oxygen is the second most abundant gas.
