100

A measurement of the amount of matter in an object. 

What is mass?

100

The 3 main layers of Earth.

What are the crust, mantle and core?

100

This phase occurs when the entire side of the Moon facing Earth is illuminated, making it appear fully lit.

What is the Full Moon?

100

This is the main reason the Earth experiences different seasons.

What is the tilt of the Earth's axis?

100

When the moon blocks out the sun from Earth's perspective.

What is a solar eclipse?

200

A measurement for the amount of space an object takes up.

What is volume?

200

The layer made up of liquid iron and some nickel. 

What is the outer core?

200

This phase occurs just after the New Moon, when a small, crescent-shaped sliver of the Moon is visible.

What is the Waxing Crescent?

200

The Earth’s axis is tilted at an angle of about 23.5 degrees, which causes different areas of the Earth to receive varying amounts of sunlight throughout the year, leading to this.

What are the seasons?

200

When the moon is in the Earth's shadow.

What is a lunar eclipse?

300

This is the relationship between mass and volume, often used to describe how much matter is packed into a certain space.

What is density?

300

The layer humans live on.

What is the crust?

300

it takes the moon one _________ to complete an entire cycle (go through all phases)

What is a month?

300

During this season in the Northern Hemisphere, the Earth is tilted toward the Sun.

What is summer?

300

The moon phase in which a lunar eclipse occurs?

What is a full moon?

400

This occurs when warmer, less dense material rises, and cooler, denser material sinks, creating a circular motion. It’s responsible for processes like ocean currents and heat transfer in the Earth's mantle.

What is a convection current?

400

This layer is the transfers heat through convection currents.

What is the mantle?
400

The illuminated portion of the moon is getting smaller every night.

What is waning?

400

The Southern Hemisphere experiences this season while the Northern Hemisphere experiences winter, as they are tilted in opposite directions.

What is summer in the Southern Hemisphere?

400

The moon phase in which a solar eclipse occurs?

What is a new moon?

500

The reason hot air rises and cold air sinks is because of differences in this property, which causes denser materials to sink and less dense materials to rise.

What is density?

500

The hottest and most dense layer. It is also made of solid iron. 

What is the inner core?

500

The percentage of the moon that is always illuminated by the sun?

What is 50%?

500

The northern and southern hemisphere experience this phenomena because they point in opposite directions due to Earth's tilt. 

What are opposite seasons?

500

The darkest part of the shadow.

What is the umbra?
