Unit 5 Review

Front

What are spring tides?

Back

Spring tides occur when the Earth, Moon, and Sun are aligned during the new or full moon, resulting in higher high tides and lower low tides.

Front

What are neap tides?

Back

Neap tides occur when the Earth, Moon, and Sun form a right angle during the first and third quarter phases of the moon, resulting in lower high tides and higher low tides.

Front

Why do people weigh less on the Moon than on Earth?

Back

A person weighs less on the Moon because the Moon has less mass and therefore less gravitational pull compared to Earth.

Front

What process formed the planetesimals in our solar system?

Back

The planetesimals were formed through the accretion of particles in the solar nebula.

Front

What causes tides on Earth?

Back

Tides are caused by the differences in the gravitational pull of the Moon and the Sun on different sides of the Earth.

Front

How old is our solar system?

Back

Our solar system is approximately 4.6 billion years old.

Front

What is the gravitational pull of the Moon compared to Earth?

Back

The gravitational pull of the Moon is about 1/6th that of Earth.

Front

What is the significance of the solar nebula in the formation of the solar system?

Back

The solar nebula is the cloud of gas and dust from which the solar system formed, leading to the creation of the Sun and planets.

Front

What is the difference between the gravitational forces of the Earth and the Moon?

Back

Earth has a stronger gravitational force due to its larger mass compared to the Moon.

Front

What are the phases of the Moon?

Back

The phases of the Moon include new moon, first quarter, full moon, and last quarter, which are determined by the Moon's position relative to the Earth and Sun.
