Fossil Evidence
This scientific rule states that in undisturbed rock layers, the oldest layer is found at the bottom.
What is the Law of Superposition?
This type of boundary forms earthquakes when plates slide past each other.
What is a transform boundary?
A watershed is best described as…
An area of land that drains into a single body of water.
Removing too many predator fish can disrupt what?
The food web.
Sustainability means meeting human needs while also protecting what?
The environment/ecosystems.
If identical plant fossils are found in South America and Africa, what does this suggest about those continents in the past?
They were once connected.
At this boundary, new oceanic crust is formed.
What is a divergent boundary?
Replacing forests with parking lots increases what?
Runoff.
Tiny plastic particles that enter marine organisms are called…
Microplastics.
A coastal town wants more tourism but also healthy reefs. What is the BEST solution?
Regulated tourism or marine protected areas.
A fossil is discovered in the top sediment layer of a cliff. Compared to fossils below it, it is…
Younger
Two continental plates collide. What landform is MOST likely created?
Mountains
Which would better protect groundwater: removing wetlands or restoring wetlands?
Restoring wetlands.
Warmer ocean temperatures can do what to the coral reef?
It can harm orangisms and habitat
What is desalination ?
Removing salt from ocean water to make fresh drinkable water
Why would a freshwater reptile fossil found on two separate continents be strong evidence for continental drift?
It likely could not cross an ocean, so the land must have been joined.
A chain of volcanic islands forms in the middle of an ocean plate. This is most likely caused by…
A hot spot
Spraying fertilizer before heavy rain could most directly impact what?
Surface water quality.
Poorly treated wastewater entering oceans can introduce what?
Pollutants or toxins.
Which is more sustainable: unlimited fishing or seasonal fishing limits?
Seasonal fishing limits.
Scientists find marine fossils on top of a mountain. What does this suggest about that area long ago?
It was once underwater.
If ocean basins are getting wider, what type of boundary is likely present?
Divergent boundary.
If groundwater levels drop over time in a community, what human activity might be responsible?
Overuse or excessive pumping of water.
How does overfishing affects ecosystems
It harms key species, low population before able to reproduce.
Why is a balanced approach usually better than extreme decisions when managing natural resources?
It considers both economic needs and environmental protection
