Precipitation... Rain or snow
If fossil fuel usage were unlimited, what effect would this have on Earth’s biosphere?
It would pollute natural habitats, which would decrease the biodiversity on Earth.
The length of time between night and day on Earth varies throughout the year. This time variance is explained primarily by what?
Earth's angle of tilt
Why are fossils rarely found in metamorphic or igneous rock?
heat and pressure
If a river has a high turbidity that means the water is what?

D. New rocks form from older rocks.
Farmers use fertilizer on their crops to increase crop yield. How does the fertilizer affect plants and animals in nearby lakes and streams?
A. Fertilizer directly kills fish and plant life in lakes and streams.
B. Fertilizer leads to the growth of oxygen-depleting organisms.
C. Fertilizer that becomes airborne pollutes the air around aquatic plants.
D. Fertilizer improves crops which draws animals away from the lakes and streams.
B. Fertilizer leads to the growth of oxygen-depleting organisms.
Temperature increases as altitude increases in both the stratosphere and the thermosphere. What is the main difference between these two layers?
Stratosphere = Ozone layer absorbs UV radiation
Thermosphere = Direct exposure to sun
