Earth's Processes
This is the process that causes rocks to break apart over time, creating sediment
Weathering
This property helps you know if something will float or sink.
Density
This is a resource that can be replaced by nature quickly.
Renewable Resource
This part of a food chain gets energy directly from the Sun.
Producers
This type of energy comes from the Sun and helps plants grow.
Light Energy
This force of nature can slowly change the shape of a canyon by carrying away rock and soil.
Erosion
You mix sugar into water and it disappears. What kind of mixture is it?
Solution
Why is wind energy better for the environment than using coal? (Give two reasons)
It is renewable and does not cause air pollution
What is one way animals depend on plants to survive in their environment? What kind of interaction is this?
They eat plants for food or use them for shelter?Bitoic interaction
Which force causes a ball to slow down as it rolls across the ground?
Friction
This landform is made by deposition after a river floods.
Delta
How can you separate a mixture of sand and iron filings?
Using a magnet
List two things you can do at home to help conserve natural resources.
Turn off light bulbs, use less water, recycle
How do sharp claws help an eagle survive in its environment?
They help it catch and hold onto prey
You rub your hands together and they get warm. What energy transformation is taking place?
Mechanical energy changing into thermal energy
How do weathering, erosion, and deposition work together to change Earth’s surface?
These are the steps in how land is broken down, moved, and built up again?
A student finds a material that is magnetic, conducts electricity, and sinks in water. What can they infer about the material?
It is a metal
How are fossil fuels formed and why are they considered nonrenewable?
Formed by decomposition of organisms. They take millions of years to form.
What might happen to a population of rabbits if their predator, the fox, disappears?
The rabbit population could grow too large and use up food resources
What type of energy is stored in food, and how does your body use it?
chemical energy, which your body uses to move
A glacier moves slowly across land, carving out a valley. Describe what processes are happening and what landforms could be created.
Erosion by ice and the formation of U-shaped valleys
A student tests the solubility, magnetism, and conductivity of five substances. How can these properties help identify unknown materials?
This can help to classify and compare materials using the properties of matter
Explain how human choices (like recycling or using solar energy) can affect the availability of natural resources in the future.
Conserving resources helps prevent us from running out of them, and protects the environment.
Explain how a drought could affect the flow of energy in a grassland food web.
Fewer plants grow, herbivores have less to eat, and carnivores may go hungry or leave the area
A box is sitting still on the floor. Two students push it with the same force from opposite sides. The box doesn't move. Is this an equal or unequal force on the box, and why does it stay in place?
Equal forces, because they cancel each other out and there is no change in motion
