Geography MCQs

Pressure differences create a force on air.
The resulting motion is modified by friction and Earth's rotation.

Sediments accumulate in layers and become lithified.
Sandstone and shale are examples.

A rain gauge collects and measures liquid precipitation.
Rainfall is commonly reported in millimeters.

Earth's rotation changes the apparent path of moving objects.
Deflection is to the right in the Northern Hemisphere and left in the Southern.

Granite cools slowly beneath Earth's surface.
Slow cooling allows large mineral crystals to form.

A wind vane points into the direction from which the wind blows.
Wind direction is named by its source direction.

Trade winds converge toward the equatorial low-pressure zone.
They blow mainly from the east.

Basalt forms when lava cools quickly at or near the surface.
It commonly makes up oceanic crust.

An anemometer measures the speed of moving air.
Cup and propeller types are commonly used.

The westerlies generally blow from west to east in the mid-latitudes.
They carry many weather systems across continents.

Limestone commonly forms from calcium carbonate sediments.
It may originate from shells, reefs, or chemical precipitation.

Relative humidity depends on both moisture content and temperature.
Warm air can generally hold more water vapor than cold air.
