Geo Processes

What is 'Tension Stress'?

• Rocks rolling down a hill

• Rocks cooling down from lava

• Rocks pulled apart at divergent/continental rifts

• Stress that pushes rocks in parallel but opposite directions

What is "Compression stress"?

• The process by which molten material adds new oceanic crust to the ocean floor

• Natural processes that happen on Earth

• It is similar to Tension acting horizontally

• Stress that squeezes rock until it folds or breaks

What is "Sea floor spreading"?

• It is a tsunami that happens near a volcano

• It is how the Himalaya mountains where created

• The process by which molten material adds new oceanic crust to the ocean floor

• It is the motion of the plates in Japan and California

Plate Tectonics

• The motion of Earth when there is an earthquake

• The smell that dogs detect in the air when rescuing people

• The movement of large parts of the Earth that meet at boundaries

• The Earth's shape millions of years ago

Transform Boundary

• Two tectonic plates that slide past each other

• Boundaries between countries that have walls

• Two tectonic plates that move apart

• Two tectonic plates that collide or move together

Convergent Boundary

• Two tectonic plates that move apart

• Stress that pushes rocks in parallel but opposite directions

• The process by which molten material adds new oceanic crust to the ocean floor

• Two tectonic plates that collide or move together

Divergent Boundary

• Two tectonic plates that move apart

• Natural processes that happen on Earth

• Two tectonic plates that collide or move together

• The process by which molten material adds new oceanic crust to the ocean floor

A rock formed from fragments of other rocks is a(n)

• Metamorphic Rock
• Sedimentary Rock
• Extrusive Rock
• Igneous Rock

If heat and pressure inside the Earth cause a rock to melt, the material that formed would be

• Metamorphic
• Magma
• Sedimentary
• Igneous

The three groups of rocks are classified by

• How they form
• Color
• Grain size
• Chemical Composition
