Front

What is the Doppler Effect?

Back

The Doppler Effect is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. It explains why galaxies moving away from Earth show a redshift.

Front

What color shift indicates that a galaxy is moving away from Earth?

Back

Red

Front

What are latitude lines?

Back

Latitude lines are horizontal lines that run parallel to the equator and measure the distance north or south of the equator.

Front

What are longitude lines?

Back

Longitude lines are vertical lines that run from the North Pole to the South Pole and measure the distance east or west of the Prime Meridian.

Front

What is an index contour line?

Back

An index contour line is a contour line that is labeled with an elevation value, distinguishing it from other contour lines.

Front

What is the significance of contour lines on a map?

Back

Contour lines represent elevation and the shape of the terrain, helping to visualize the topography of an area.

Front

What are convection cells?

Back

Convection cells are large-scale movements of fluid (like air or water) caused by differences in temperature and density, driving processes such as plate tectonics.

Front

What is the relationship between convection cells and plate tectonics?

Back

Convection cells in the Earth's mantle create movement that drives the tectonic plates, leading to geological activity such as earthquakes and volcanic eruptions.

Front

What is the range of longitude values?

Back

Longitude values range from 0 to 180 degrees east and west of the Prime Meridian.

Front

What is the range of latitude values?

Back

Latitude values range from 0 to 90 degrees north and south of the equator.
