What is the North Star?

Back

The North Star, also known as Polaris, is the star that Earth's axis is always pointed at. It is used for navigation because it remains in a fixed position in the sky.

Front

What is the axis of the Earth?

Back

The axis is an imaginary line that runs through the North and South poles of the Earth, around which the Earth rotates.

Front

What are spring tides?

Back

Spring tides occur when the Earth, Moon, and Sun are aligned, typically during the new and full moon phases, resulting in higher high tides and lower low tides.

Front

What is the equator?

Back

The equator is an imaginary line that runs around the Earth at 0 degrees latitude, dividing the Earth into the Northern and Southern Hemispheres.

Front

What is revolution in terms of Earth’s movement?

Back

Revolution refers to the movement of the Earth around the Sun, taking approximately 365.25 days to complete one full orbit.

Front

What is rotation in terms of Earth’s movement?

Back

Rotation is the spinning of the Earth on its axis, which takes about 24 hours to complete one full turn, resulting in day and night.

Front

What is the difference between spring and neap tides?

Back

Neap tides occur when the Earth, Moon, and Sun form a right angle, resulting in lower high tides and higher low tides, while spring tides occur when they are aligned.

Front

What is latitude?

Back

Latitude is the measurement of distance north or south of the equator, expressed in degrees.

Front

What is longitude?

Back

Longitude is the measurement of distance east or west of the Prime Meridian, also expressed in degrees.

Front

What is the significance of the Prime Meridian?

Back

The Prime Meridian is the imaginary line at 0 degrees longitude, serving as the starting point for measuring longitude and dividing the Earth into Eastern and Western Hemispheres.
