Ecosystems
Animals that eat plants are called this.
Herbivore
Magma that reaches Earth's surface is called this.
Lava
The three common states of matter.
Solid, liquid, gas
The Sun is Earth's main source of this.
Energy
Plant structure that absorbs water.
Roots
A possible explanation for observations.
Hypothesis
A living thing in an ecosystem.
Organism
How can weathering make erosion happen more quickly?
Weathering breaks rocks up into smaller pieces that are easier to move.
Matter has this and takes up space.
Mass
Energy of motion.
Kinetic energy

The arctic
An explanation supported by evidence and reasoning.
A scientific claim
An organism that breaks down dead plants and animals.
Decomposer
Wind, water, ice, and gravity are all agents of what process?
Erosion
Matter changing from liquid to gas.
Evaporation
Stored energy.
Potential Energy
The structure where photosynthesis mostly occurs.
Leaves
A factor changed on purpose in an investigation.
An independent variable
When too many deer live in an area, they may eat plants faster than they can regrow. What is this called?
Overpopulation
The layer of Earth made of solid rock beneath our feet.
Crust
A property used to identify a substance.
density, color, texture, etc.
Energy transferred through vibrations.
Sound
Structures inherited from parents that help organisms survive.
Inherited traits
Data described with words.
Qualitative date
A disease wipes out most producers in an ecosystem. Why would this affect nearly every other organism?
Because producers are the base of a food web.
A sudden movement of Earth's crust causing shaking.
Earthquake
When a substance changes into a different substance.
Chemical change
Energy that travels as waves and allows us to see.
Light energy
Animal body parts that help it survive.
Adaptation
Data involving measurements or numbers.
Quantitative data
