Earth Sun and Moon ( Movement, Tides and Eclipses)

Why do the tides change every 6 hours?

• The earth is rotating and it takes 24 hours to turn on its axis.

• The moon's gravitational pull affects the tides every 6 hours.

• The sun's position changes every 6 hours, influencing the tides.

• The ocean currents shift every 6 hours, causing the tides to change.

What is the difference between spring and neap tides?

• Spring tides occur during full and new moons when the Sun, Moon, and Earth are aligned; neap tides occur during the first and third quarters of the moon when the Sun and Moon are at right angles to each other.

• Spring tides occur when the Moon is at its closest point to Earth; neap tides occur when the Moon is at its farthest point from Earth.

• Spring tides happen only in the summer months; neap tides happen only in the winter months.

• Spring tides are higher than average tides; neap tides are lower than average tides.

Why can we predict the phases of the moon?

• Because the moon orbits the earth in a random pattern.

• Because the moon orbits the earth in a repeating pattern every 27.3 days.

• Because the moon's phases are influenced by the sun's position only.

• Because the moon changes its orbit every month.

What is a solar eclipse?

• A solar eclipse occurs when the Earth passes between the Moon and the Sun.

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

• A solar eclipse occurs when the Sun passes between the Earth and the Moon.

• A solar eclipse occurs when the Earth blocks the light from the Moon.

What is the Earth's orbit around the Sun called?

• Rotation

• Revolution

• Translation

• Circumference

What happens to the seasons when the Earth is tilted towards the Sun?

• It experiences winter.

• It experiences autumn.

• It experiences summer.

• It experiences spring.

Why does the moon go faster or slower in its orbit around the Earth?

• The moon's speed is constant regardless of its position.

• The moon's orbit is a perfect circle, so speed remains the same.

• The orbit is an ellipse and sometimes the moon is closer, so gravity pulls it around faster.

• The moon's speed is affected by the Earth's rotation.

What is a lunar eclipse?

• A lunar eclipse occurs when the Earth passes between the Sun and the Moon, casting a shadow on the Moon.

• A lunar eclipse happens when the Moon passes between the Earth and the Sun, blocking sunlight.

• A lunar eclipse is when the Earth moves into the shadow of the Moon during a new moon.

• A lunar eclipse occurs when the Sun is directly behind the Earth, illuminating the Moon.

Why do the tides change in a cyclic pattern?

• The earth is rotating and takes 24 hours to do so, causing high tide on the side facing the moon and low tide on the opposite side.

• The sun's gravitational pull is the only factor affecting tides, leading to a constant pattern.

• Tides change due to the Earth's distance from the sun, which varies throughout the year.

• The moon's phases directly determine the timing of high and low tides, regardless of the Earth's rotation.

What is the significance of the equator in relation to seasons?

• The equator experiences little seasonal variation in temperature compared to regions farther from it.

• The equator has the most extreme seasonal changes in temperature.

• The equator is the coldest region on Earth during winter.

• The equator experiences four distinct seasons like temperate regions.
