What are the phases of the Moon?

Back

The phases of the Moon are the different shapes of the Moon as seen from Earth, which change over a cycle of about 29.5 days. The main phases are new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent.

What is a new moon?

Back

A new moon is the phase of the Moon when it is positioned between the Earth and the Sun, making it invisible from Earth.

Front

What causes night and day on Earth?

Back

Night and day are caused by the rotation of the Earth on its axis. When one side of the Earth faces the Sun, it experiences daytime, while the opposite side experiences nighttime.

Front

What happens to water vapor in the atmosphere?

Back

As water vapor rises, it cools down and condenses into liquid water, forming clouds. Eventually, this water falls back to Earth as precipitation.

Front

What is runoff in the water cycle?

Back

Runoff is the water that flows over the ground surface when the soil is saturated and cannot absorb any more water.

Front

Why does water vapor not escape into outer space?

Back

Water vapor does not escape into outer space because as it rises, it cools down, condenses into liquid, and falls back to Earth as precipitation.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, involving processes like evaporation, condensation, precipitation, and runoff.

Front

What is the significance of the Moon's phases?

Back

The phases of the Moon are significant for understanding time, tides, and various cultural events. They also help in studying the Moon's orbit and position relative to Earth and the Sun.

Front

What is saturation in the context of soil?

Back

Saturation occurs when the soil is filled to its maximum capacity with water, preventing it from absorbing any more water.

Front

What is evaporation?

Back

Evaporation is the process by which liquid water turns into water vapor and enters the atmosphere, usually due to heat from the Sun.
