On a visit to a beach along the Atlantic Ocean, Ana noticed that sometimes the water was closer to her feet and hours later it was far away. Her father told her that this difference was caused by the rise and fall of tides. What is the main cause of ocean tides?

• The rotation of the Earth

• The magnetic fields around the Earth

• The revolution of the Earth around the Sun

• The gravitational pull of the Moon

Earth experiences a cycle of temperature changes that result in seasons, such as summer and winter. Which statement best describes how seasons result from the Sun’s impact on Earth?

• Seasons occur because Earth orbits the Sun in a path that is a perfect circle.

• Seasons occur because Earth’s axis is tilted.

• Seasons occur because the Sun’s axis is tilted.

• Seasons occur because the Earth’s distance from the Sun changes throughout the year.

Gravity is an attractive force that exists between all objects that have mass. What role does gravity play in determining the motion of the Earth?

• Earth’s gravitational pull on the Sun causes Earth to orbit the Sun.

• The Sun’s gravitational pull on Earth causes the Sun to orbit the Earth.

• Earth’s gravitational pull on the Sun causes the Sun to orbit the Earth.

• The Sun’s gravitational pull on the Earth causes Earth to orbit the Sun.

The phases of the moon can be categorized as waxing or waning based on where they occur in the lunar cycle. Why does the sequence of phases of the moon always occur in the same order?

• The lunar cycle is consistent because it is based on Earth’s revolution around the Sun.

• The lunar cycle is consistent because it is based on Earth’s rotation around its axis.

• The lunar cycle is consistent because it is based on the moon’s revolution around Earth.

• The lunar cycle is consistent because it is based on the moon’s rotation around its axis.

What is occurring in the image below, and how would the Moon appear from Earth’s surface if these objects were positioned as shown in the image?

• This is a lunar eclipse. From Earth, the Moon would be invisible because sunlight can’t reach it.

• This is a solar eclipse. From Earth, the Moon would be invisible because sunlight can’t reach it.

• This is a lunar eclipse. From Earth, the Moon would be slightly visible.

• This is a solar eclipse. From Earth, the Moon would be slightly visible.

Both the Sun and the Moon influence Earth's tides, but the Moon's influence is greater than the Sun's. Why is this the case?

• The Moon's gravitational force deflects the Sun's gravitational force.

• The Sun has more mass than the Moon, but the Moon is much closer to Earth than the Sun, so its gravitational force on Earth is greater.

• The Sun's gravitational force changes more dramatically than the Moon's gravitational force as Earth orbits the Sun and the Moon orbits Earth.

• The Sun's gravitational force on Earth is reduced because of the planets that are between the Sun and Earth.
