True
100
What is erosion?
The process by which water, ice, wind, or gravity moves fragments of rock and soil.
200
How can we make an experiment more reliable?
Do the experiment over and over again to get reliable results
200
What affects friction? Give examples
Changing the surface where you are sliding object.
200
How does weathering affect mountains?
Over time it reduces their size by the process of breaking down rocks and sediment

What can fossils tell us about the past and the environment?
What can fossils tell us about the past and the environment?
They can tell us what was the environment like in the past. For example, they tell us what kind of animals and plants lived

300
Why is burning fossil fuel bad for the environment?
Burning fossil fuel is bad for the environment because it leads to global warming
300
What is gravity?
Force that pulls objects towards the Earth

What does nonrenewable mean? Give example of nonrenewable energy?
Nonrenewable means it cannot be created again within a short amount of time. Example of nonrenewable energy include coal, oil and natural gas

Why is it important to follow rules while conducting an experiment?
Because rules provide guidelines to follow and tell you what to do
500
What is geothermal?
Energy that is produced from the heat of the Earth

How long does it take for fossil fuels to be formed?
It takes over million of years for fossils to be formed
500
True
True or False
Gas and oil come from the layers of sedimentary rocks
