If two continents move toward each other, what landform forms and how? What is this plate boundary?
S – Signal:Put your finger on your nose when you’re ready.
S – Stem:
1. This is a ______ boundary because...
2. I predict that __________ will form because…
S – Share: Share with your table partner.
This is a convergent boundary because they are colliding and crashing into each other.
I predict that mountains, trenches, or volcanoes will form because when the two plates collide, they sometimes subduct and remelt and turn into volcanoes and trenches.

Student A: “Earthquakes don't happen when two tectonic plates collide and release energy.”
Student B: “Earthquakes only happen when plates move apart.”
Question: are they both right or both wrong and why?
both are incorrect because earthquakes can occur at any plate boundary. When plates shift at all there could be earthquakes occurring.

What causes tectonic plates to move?
Convection currents in the asthenosphere.
But Why are there convection currents? Where on our earth is it the hottest? TURN AND TALK

This is the name of the plate boundary where 2 plates move apart.
Divergent Boundary.
200 points extra for Why are they moving apart? Talk to your team about why it is moving

When two oceanic plates diverge, they cause the sea floor to spread creating mid-ocean ridges and ______ basins.
Ocean basin

When two oceanic plates move in these directions, we get what kind of landforms?
Ocean basins/mid-ocean ridge

This location sits over a hotspot in the middle of the Pacific Plate. As the plate moves over the hotspot, an island chain forms. What is the name of this island chain?
Hawaiian Islands

This formation is caused when two continental plates diverge?
Rift Valley

This is a rift valley which is formed at what kind of boundary?
Divergent boundary

This location is where two oceanic plates converge, creating a deep ocean trench?
Mariana Trench
Extra 400 points for the team that can explain what causes a trench. Turn and talk with your group before answering.

Student A: “Finding whale fossils in the desert proves that whales lived on land millions of years ago.”
Student B: “Finding whale fossils in the desert shows that the area was once covered by an ocean.”
Question: Who is correct and why?
Student B is correct because finding fossils in the desert shows that the area was once covered by an ocean a long time ago. This shows that the earth has changed over time.
