This state of matter has a fixed volume, but takes the shape of its container.
A liquid
Organisms like plants that make their own food using sunlight, water, and carbon dioxide.
The Sun
The Earth completes one full rotation on its axis in this amount of time.
24 hours/1day
This sphere includes all of Earth's liquid water, ice, and water vapor.
The Hydrosphere
The force that pulls objects toward the center of the Earth.
Gravity
The small building blocks that make up all matter.
Atoms
Organisms like plants that make their own food using sunlight, water, and carbon dioxide.

False
Bacteria and fungi belong to this group because they break down dead plants and animals.
Decomposers
The reason the Sun appears so much larger and brighter than other stars in the night sky.
It is the closer to Earth
The gases surrounding Earth, mostly made of nitrogen and oxygen.
The Atmosphere
When two forces acting on an object are equal in size and opposite in direction, the forces are described as this.
Balanced Forces
Mixing baking soda and vinegar causes bubbles and a temperature change, which is evidence of this type of change.
Chemical Change
A complex network made up of many interconnected food chains.
A Food Web
The reason the Sun appears so much larger and brighter than other stars in the night sky.
Revolution/Orbit
This sphere includes all of the solid ground, rocks, minerals, soil, and landforms on Earth.

A Force
The property that measures how easily a substance dissolves in liquid.
Solubility
Plants get most of the materials they need for growth from these two non-living things, rather than soil.
Water and Air
What is the name of the galaxy that our Solar System is located in?
The Milky Way
The most abundant gas in Earth's atmosphere, making up the majority of the air we breathe.
