Seasons and Tides: Earth and Moon

What is a lunar month?

• The time it takes for the moon to complete one full cycle of phases, about 29.5 days.

• The time it takes for the Earth to orbit the Sun, about 365 days.

• The time it takes for the moon to orbit the Earth, about 27.3 days.

• The time it takes for the moon to rotate on its axis, about 24 hours.

What causes the seasons on Earth?

• The distance of Earth from the sun.

• The tilt of Earth's axis as it revolves around the sun.

• The shape of Earth's orbit around the sun.

• The amount of sunlight received by Earth.

When is it winter in the Northern Hemisphere?

• When the Northern Hemisphere is tilted away from the sun.

• When the Northern Hemisphere is tilted towards the sun.

• When the Northern Hemisphere is experiencing the longest day of the year.

• When the Northern Hemisphere is at its closest point to the sun.

What is the difference between spring tides and neap tides?

• Spring tides are lower and occur during first and third quarter moons; neap tides are higher and occur during full and new moons.

• Spring tides are higher and occur during full and new moons; neap tides are lower and occur during first and third quarter moons.

• Spring tides occur only in summer; neap tides occur only in winter.

• Spring tides are caused by the Earth's rotation; neap tides are caused by the moon's gravitational pull.

What is the relationship between Earth's tilt and climate?

• Earth's tilt has no effect on climate.

• Earth's tilt affects the intensity and distribution of sunlight, influencing climate and seasons.

• Earth's tilt only affects the temperature of the poles.

• Earth's tilt is responsible for ocean currents.

How do the sun and moon affect tides?

• The sun has a stronger effect on tides than the moon.

• The gravitational pull of the moon has a stronger effect on tides than the sun, but both contribute.

• Tides are only affected by the sun's gravitational pull.

• The moon and sun do not affect tides at all.

If it is spring in North America, what season is it in South America?

• Winter

• Summer

• Fall

What is the primary cause of tides on Earth?

• The sun's gravity.

• The moon's gravity.

• Earth's rotation.

• Ocean currents.

What is the tilt of Earth's axis?

• 22.5 degrees

• 23.5 degrees

• 24.5 degrees

• 25.5 degrees

What is the equinox?

• A time when day and night are approximately equal in length, occurring in spring and fall.

• A day when the sun is at its highest point in the sky.

• A period of time when the weather is consistently warm and sunny.

• A moment when the moon is directly between the Earth and the sun.
