physical processes exam

Which of the following processes is occurring when rainwater moves volcanic rock?

• Folding
• Erosion
• deposition
• Faulting

Above a hot spot under an oceanic plate, large quantities of lava continually erupt through the seafloor. If the lava builds up to an elevation greater than sea level, what type of landform will result?

• Barrier Island
• Peninsula
• Volcanic Island
• Continent 

Which provides the best evidence for the theory that faults and volcanoes are results of tectonic plate interactions?

• Faults on tectonic plates are in constant motion, but volcanoes may not erupt for many years.
• Faults and volcanoes existed long before there were tectonic plates.
• Tectonic plates that have many faults do not usually have volcanoes.
• Faults and volcanoes are often found at tectonic plate boundaries.

Which process caused the upward movement that formed the Andes Mountains?

• Sea floor spreading 
• Deposition 
• Convergent boundaries
• erosion of rock layer

Dust storms can occur when
