The process where Earth's plates are moving.
What is plate tectonics?
What is the original source of energy for most food chains?
The sun
What is the positively charged part of an atom called?
Proton
Name one fossil fuel
Coal, oil, or natural gas
Process breaking rocks into smaller pieces
Weathering
What organism makes its own food?
Producers
Characteristics that can be observed or measured without changing chemical identity
Physical Propery
What are the gasses called that are released into the atmosphere that can cause heat to be reflected?
Greenhouse gasses
Name two different plate boundaries
Transform, convergent, divergent
What is the process where plants make their own food?
Photosynthesis
What is made in a chemical reaction
products
What type of material is made by humans through chemical processes
synthetic materials
What are the three different types of rocks and explain how one type is created.
Igneous, Metamorphic, and Sedimentary
In a food chain, why is there less energy available at higher levels?
Energy is lost as heat and used by organisms
What happens to heat in an exothermic reaction?
Heat is released
Explain the difference between renewable and non renewable resources
Renewable can be used again and again nonrenewable takes a long time to be replaced.
Explain how weathering, erosion, and deposition work together to change Earth’s surface.
Weathering breaks down rock, erosion moves it, and deposition drops it in a new location.
A hawk eats a snake, which ate a mouse, which ate grass. Which organism receives the least energy?
The hawk
Compare a physical change and a chemical change and give an example of each
Physical changes alter appearance but not identity (melting ice); chemical changes create a new substance (rusting iron).
Explain how increased greenhouse gases can affect both Earth’s climate and ocean life
They increase global temperatures, warm oceans, contribute to ocean acidification, and harm marine organisms.
