A. the mantle and outer core
B. the crust and upper mantle
B. the crust and upper mantle
Mountains can be formed when one plate is forced under another. The plate on top folds up like an accordion and forms mountains. The plate forced under usually melts. What event is most likely to occur after much of the plate forced under has melted?

Which statement correctly describes the outer core?
B. Composed primarily of iron and nickel, the outer core is a liquid layer that rotates around the inner core, and is responsible for Earth's magnetic field.
C. Composed primarily of silica particles, the outer core is the outermost layer of Earth, and varies in temperature and thickness
B. Composed primarily of iron and nickel, the outer core is a liquid layer that rotates around the inner core, and is responsible for Earth's magnetic field.
What is the BEST explanation for what will most likely occur at this type of plate boundary? A tectonic plate boundary.
A. Volcanic eruptions will occur because the plates slide past each other.
B. Earthquakes will occur when the two different plates slide pass each other.
B. Earthquakes will occur when the two different plates slide pass each other.
What does the theory of continental drift state?
A. All the continents were once one continent that broke up and drifted apart over hundreds of millions of years.
B. The continents have always been separate but may one day drift together to form a single continent.
A. All the continents were once one continent that broke up and drifted apart over hundreds of millions of years.

What must happen within Earth for a volcano to form?
A. Hot water just under the crust must convect, slowly moving as heat circulates from the mantle to the bottom of the crust, until pressure increases and it erupts.
B. Hot magma in the mantle must convect, slowly moving as heat circulates from the core to the surface, and pulling or pushing the tectonic plates.
