Is our current nuclear energy created from splitting uranium atoms or fusing them?
Splitting! Also known as "fission".
In your own words, what is bedrock?
The solid layer of rock beneath the soil.
Which three elements are commonly found in fertilizers, as they are super important to plants?
Nitrogen, phosphorus, and potassium
The two types of weathering are ...

What's the biggest advantage of nuclear energy when fighting climate change?
Nuclear energy emits no Carbon Dioxide
Hmmm, in relation to landfills, what in the world is leachate?
The polluted liquid produced by water passing through buried wastes in a landfill
Name 3 renewable resources.
Water, wind, sunlight, trees
Mechanical weathering does not change a rock’s ________.
Composition!
"Fracking" is slang for ________ ________.
Hydraulic Fracturing
What is topsoil?
The mixture of humus, clay, and other minerals that forms the crumbly, topmost layer of soil.
Lake Pyramid in Nevada is an endorheic basin. What's that mean?
It's a drainage basin, or watershed, that does not flow to one of the Earth's major oceans.

How would you describe erosion?
The movement of rock and sediment due to wind, water and other forces.
"Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Water, sand and chemicals are injected into the rock at high pressure which allows the gas to flow out to the head of the well."
Tell me about the nitrogen cycle!
It's the transfer of nitrogen from the atmosphere to the soil, to living organisms, and back to the atmosphere.
Erosion can lead to silt being washed into the ocean. How can that mess with the ecosystem? (Hint: plankton)
Large amounts of silt can block sunlight, preventing the plankton from photosynthesizing. oof
