What is a solar eclipse?

Back

A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking the Sun's light.

Front

Why are total solar eclipses rare at a specific location?

Back

Total solar eclipses are rare at a specific location because the Moon's orbit is tilted, causing it to pass slightly above or below the line between the Sun and Earth.

Front

What causes ocean currents?

Back

Ocean currents are caused by the movement of water due to differences in temperature and salinity, as well as wind.

Front

What are spring tides?

Back

Spring tides are higher than normal tides that occur when the Sun, Moon, and Earth are aligned, resulting in stronger gravitational pull.

Front

What is a lunar eclipse?

Back

A lunar eclipse occurs when the Earth passes between the Sun and the Moon, causing the Earth's shadow to cover the Moon.

Front

What is the role of gravity in tides?

Back

Gravity from the Moon and Sun affects tides by pulling water towards them, creating high and low tides.

Front

What is the difference between neap tides and spring tides?

Back

Neap tides occur when the Sun and Moon are at right angles to each other, resulting in lower high tides, while spring tides occur when they are aligned, resulting in higher high tides.

Front

What is the significance of the Moon's tilted orbit?

Back

The Moon's tilted orbit affects the occurrence of solar and lunar eclipses, making them less frequent.

Front

What are ocean basins?

Back

Ocean basins are large depressions on the Earth's surface that hold the oceans and are shaped by geological processes.

Front

How does temperature affect ocean water movement?

Back

Colder water sinks while warmer water rises, creating movement and circulation in the ocean.
