What causes the Moon's phases as observed from Earth?

Back

The Moon's phases are caused by its revolution around Earth, which changes the portion of the Moon that is illuminated by the Sun as seen from Earth.

What happens to daylight duration when the Northern Hemisphere is tilted toward the Sun?

Back

Daylight duration is longer when the Northern Hemisphere is tilted toward the Sun.

Front

Why is summer generally warmer than winter?

Back

Summer is warmer than winter because the hemisphere experiencing summer is tilted more directly toward the Sun, receiving more direct sunlight.

Front

What type of tide results in very high high tides and very low low tides?

Back

Spring tides result in very high high tides and very low low tides.

Front

Why does the Moon have a greater influence on Earth's tides than the Sun?

Back

The Moon has a greater influence on Earth's tides than the Sun because it is closer to the Earth.

Front

What is the definition of a solar eclipse?

Back

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

Front

What is the role of gravity in the formation of tides?

Back

Gravity from the Moon and the Sun pulls on Earth's water, creating bulges that result in 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 and higher low tides, while spring tides occur when the Sun and Moon are aligned, resulting in higher high tides and lower low tides.

Front

How does the tilt of the Earth affect seasons?

Back

The tilt of the Earth causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the changing seasons.
