Front

What is a contour interval?

Back

The contour interval is the vertical distance or difference in elevation between contour lines on a map. For example, if the contour interval is 20 m, each contour line represents a change in elevation of 20 meters.

Front

What happens to air temperature when a cold front approaches?

Back

When a cold front approaches, the air temperature typically decreases as the cold air mass replaces the warmer air.

Front

What is the composition of Earth's current atmosphere?

Back

Earth's current atmosphere is composed of approximately 78% nitrogen, 21% oxygen, 0.9% argon, and 0.037% carbon dioxide.

Front

What shape do planets orbit the Sun in?

Back

Planets orbit the Sun in an elliptical shape.

Front

How do you determine the coordinates of a location?

Back

Coordinates are determined by the latitude and longitude of a location. For example, Location D is at 30°N, 90°W.

Front

What is the significance of contour lines on a map?

Back

Contour lines represent elevation and the shape of the terrain. They help in understanding the topography of an area.

Front

What is a cold front?

Back

A cold front is a boundary between a cold air mass and a warm air mass, where the cold air pushes under the warm air, often leading to a drop in temperature and precipitation.

Front

What is the role of nitrogen in the atmosphere?

Back

Nitrogen is the most abundant gas in the atmosphere, making up about 78%. It is inert and does not readily react with other substances, providing stability to the atmosphere.

Front

What is an ellipse?

Back

An ellipse is a geometric shape that resembles a flattened circle. In astronomy, it describes the orbits of planets around the Sun.

Front

What is latitude and longitude?

Back

Latitude is the distance north or south of the equator, while longitude is the distance east or west of the Prime Meridian. Together, they define a specific location on Earth.
