Tectonic Plates
That the Earth's crust is made up of different pieces that fit together like a puzzle. They float on the mantle.
What causes an earthquake?
Plate tectonics/movement. Transform boundaries. Crustal rock breaking/deforming under stress and strain.
What type of plate boundary creates mountains?
Convergent plate boundaries.
What is the difference between magma and lava?
Magma is underground, lava is above ground.
What is baby yoda's real name?
Grogu
What is subduction?
When convergent plates collide, the denser plate will sink below the less dense plate, and melt back into magma.
What is the difference between the focus and the epicenter of an earthquake?
The focus is where the rock moved deep in the crust. The epicenter is the point on the surface of the crust directly above the focus.
What is a seamount?
An underwater mountain. (Sea-mountain).
How do island chains form?
Oceanic hotspots allow for magma to cool in the water, creating an island. As the oceanic crust moves over the stationary hot spot in the mantle, it creates islands in row.
What is the most spoken language in the world?
Mandarin
What is seafloor spreading?
Divergent boundaries on the sea floor where magma comes to the surface, cools off, and solidifies. Creating new crust.
What is the difference between primary (P) waves and secondary (S) waves?
What is orogeny?
What is a pyroclastic flow?
A mix of tephra (lava and rock) mixed with gases that come out of a volcano.
Which company owns Lamborghini, Ducati, Porsche, Audi, and Bugatti?
Volkswagen
What are convection currents?
The movement of hot magma rising and cool magma sinking to create a cycling current.
How long does it take an S wave to travel 4,000 km?
14.4 minutes
How are the densities of oceanic and continental crust different?
Oceanic crust is more dense because it's saturated with water. Continental crust is less dense.
What is the name of a hotspot that occurs under continental crust?
Flood Basalt
As of today, who has the most followers on Instagram?
Cristiano Ronaldo (616 million)
Lionel Messi (496 million)
Selena Gomez (429 million)
Why isn't the Earth getting bigger?
When plates move subduction happens at convergent boundaries, where the Earth's crust is recycled back down into the mantle.
If the arrival time of the P Wave is 4 minutes, and the arrival time of the S Wave is about 7.4 minutes, how far away are you from the epicenter of the Earthquake?
2,000 km.
How are isostasy and erosion related? Use the word roots in your answer.
As erosion breaks down the top of the mountain, the roots of the mountain push up through the crust, allowing the mountain to maintain isostasy.
Draw and label a volcano with the following features: magma chamber, conduit, crater, vent, ash cloud, and lava.
