What are fossils?
The solid layer of Earth between the crust and the core
The mineralized remains of organisms
The thin, solid, outermost layer of Earth
The process of continental drift
What is the main difference between the crust and the mantle?
The crust is solid, while the mantle is liquid.
The crust is thinner and solid, while the mantle is thicker and semi-solid.
The crust is made of fossils, while the mantle is made of minerals.
The crust is the innermost layer, while the mantle is the outermost layer.
Which of the following best describes plate tectonics?
A place where two tectonic plates collide
A theory explaining the movement of tectonic plates on the mantle
A huge piece of the Earth's crust
A place where two tectonic plates move apart
Which of the following best describes seafloor spreading?
A place where two tectonic plates collide
A phenomenon by which magma from Earth’s mantle comes up at the mid-ocean ridge and creates new oceanic crust
A huge piece of the Earth's crust
A place where two tectonic plates move apart
Which of the following best describes continental drift?
The theory that continents were once connected but have drifted apart
A phenomenon by which magma from Earth’s mantle comes up at the mid-ocean ridge and creates new oceanic crust
A huge piece of the Earth's crust
A place where two tectonic plates move apart
What is the key characteristic of a convergent boundary?
Plates move apart
Plates collide
Plates remain stationary
Plates slide past each other
What is the key characteristic of a divergent boundary?
Plates move apart
Plates collide
Plates remain stationary
Plates slide past each other
What is magma?
Solid rock found on Earth's surface
Melted, or molten, rock material beneath Earth's surface
A type of sedimentary rock
A layer of Earth's atmosphere
What happens to the denser plate during subduction?
It rises to the surface
It is pushed downward beneath a less dense plate
It forms a mid-ocean ridge
It creates new oceanic crust
What is a trench in geological terms?
A mountain range formed by tectonic activity
A deep and narrow depression in the seafloor where subducted plates move into the asthenosphere
A flat plain formed by sediment deposition
A volcanic crater formed by magma eruption
What causes the formation of a trench in the seafloor?
The collision of two continental plates
The subduction of one tectonic plate beneath another
The spreading of tectonic plates at a mid-ocean ridge
The erosion of the seafloor by ocean currents
rock, fossil, and seafloor spreading
