According to this chart, which three sources of greenhouse gas emissions made up 77% of our total emissions in 2019?
transportation, electricity, and industry
What changes metamorphic rock into igneous rock?
melting & crystallization
What are the 4 layers of the Earth from the OUTSIDE layer to the INSIDE layer?
Crust, Mantle, Outer Core, Inner Core
Why are fossil fuels considered a nonrenewable resource?
It takes millions of years for them to form, so we use them faster than we can replace them.
Where is MOST of Earth's freshwater located?
Polar ice caps & glaciers
What comes after runoff in the water cycle?
collection
How is the Sun the major source of energy in the water cycle?
It provides the energy to evaporate water on Earth into the atmopshere.
As you dive farther down into the ocean, how would the light, temperature, and pressure change?
light and temperature decrease, pressure increases
Summarize what happens during the rock cycle.
Rocks are always changing and any type of rock can be turned into another type by natural processes.
Meg’s teacher asks her to do a scratch test to identify an unknown mineral. Meg discovers that Feldspar can scratch the mineral, but Fluorite cannot scratch it. Which mineral must it be?
apatite
All clouds and weather activity occur in which layer of the atmopshere?
Troposphere
How do wind and water change rocks over time?
They change the shape of the rocks by removing sediment.
Which three natural processes are happening at point A on this diagram of the rock cycle?
deposition, copaction, & cementation
What would happen to the solar system if the force of inertia suddenly disappeared?
Everything would be sucked into the sun
Why does the Moon have a greater gravitational pull on Earth's water than the Sun?
The Moon is closer than the Sun
What are the layers of the atmosphere, starting at the surface of the Earth?
Mineral X is non-metallic and shows fracture. Scratch tests determine that its hardness is 7. The mineral is red, but the streak is white. What is mineral X?
garnet
Which two layers of Earth are made of hard, rigid material that does not flow?
crust & inner core
Fossils of a dinosaur species have been found in South America and Africa; two continents separated by an ocean. The dinosaur could not swim or fly. What does this suggest about the continents of South America and Africa?
The continents were once connected.
Which force of motion is most responsible for keeping the planets in constant motion?
inertia
Why does the moon appear to change shape in the sky?
As the moon revolves around Earth, we see it from different angles.
The O Horizon in this diagram is composed MAINLY of...
Decaying organic material
A large canyon with a river running through the bottom was MOST LIKELY formed by which natural process?
erosion
How would you describe the position of our solar system in the Milky Way galaxy?
It is in the Orion outer spiral arm.
Rainwater mixes with carbon dioxide in the air as it sinks into the ground, turning it into a weak acid. This acidic water dissolves limestone underground and causes a cave to form. This is an example of which type of weathering?
chemical
