Plate Tectonics
This type of plate boundary occurs when two plates slide past each other horizontally, often causing earthquakes.
What is a transform boundary?
This term describes a resource that is naturally replenished and won't run out on a human timescale, such as sunlight or wind.
Renewable Resource
This term describes a relationship where both organisms involved benefit, such as a bee getting nectar while pollinating a flower.
Mutualism
This type of plate boundary occurs when two plates collide.
What is a divergent plate boundary?
This term describes a resource that takes millions of years to form and is being used much faster than it can be replaced.
Nonrenewable Resource
This term describes a relationship where one organism benefits and the other is neither helped nor harmed, like a bird nesting in a tree.
Commensalism
This process occurs when a denser oceanic plate is forced underneath another plate and sinks into the mantle. "When one plate slide under another"
Subduction.
A farmer plants a new crop of corn every year to be turned into ethanol fuel for cars. Because this resource can be regrown season after season, it is classified this way.
This term describes a relationship where one organism benefits at the expense of another, such as a tick feeding on a deer's blood.
Parasitism
This ancient supercontinent is believed to have contained all of Earth's landmasses before they slowly drifted apart into the continents we see today.
Pangea
A city relies entirely on burning coal for electricity. Engineers warn that at current usage rates, the region's coal supply will run out within 80 years, and no new coal will form to replace it during that time. This scenario best illustrates the core problem with relying on this category of resource.
Non-renewable resource.
This term describes competition that occurs between two different species that rely on the same limited resource, such as two bird species competing for the same insects.
interspecific competition
This scientist is credited with first proposing the theory of continental drift in the early 1900s, suggesting that continents were once joined together and had since moved apart.
Alfred Wegner
This ecological rule states that only about this percentage of energy is transferred from one trophic level to the next in a food chain, while the rest is lost as heat.
10 Percent Rule.
