Forces that shape Earth’s surface by building up mountains and landmasses are called___________
• Constructive forces
• A ball of dense solid metal composed primarily of nickel and iron is the Earth’s____________
• inner core
• The place where two plates come together is known as a
• Convergent boundaries
• When Two continental boundaries collide a ______________ is formed
• Mountain
• If you were to study Geology in college you could become a __________
• Geologist
• In a transform boundary plates__________________________
• Slip by one another
• ______________is the term used to describe the sea floor sinking into ocean trenches.
• Subduction
• What is the name of the technology that used sound waves to map the ocean floor?
• Sonar
• The name of the Super Continent
• Pangaea
• Wegner’s theory that the continents have drifted apart is known as
• Theory of Continental Drift
• Sea floor spreading occurs along a ____________ boundary
• Divergent
• Example :Mid Oceanic Ridge
• Forces that wear down land masses are called____________forces
• Destructive forces
• The outer layer of earth is called the ________
• crust
• Continental crust is composed mainly of___________
• Granite
• Oceanic crust is composed mainly of_______
• Basalt
• The Cascade Mountain range occur along a __________________boundary
• Continental/Oceanic convergent boundary
• The lithosphere (plates) float on top of the _________________
• Aesthenosphere
• San Andreas fault is an example of a ______________________boundary
• Transform
• Plates slip by one another
• Temperature and pressure ________ as you go deeper into the Earth
• increase
• In this type of boundary the older denser oceanic crust dives below the oceanic crust, heats up, and melts -- finds a weak spot in the crust resulting in a volcano.
• Oceanic/Oceanic continental crust
• Example Japan
• In this type of boundary the older dense oceanic crust dives below the continental crust. The oceanic crust will melt and push up through a weak spot in the continental crust form a volcano.
• Continental/oceanic convergent boundary
• Example-Cascade Mountains
