The area around the Pacific Ocean with volcano and earthquake activity.
What is the Pacific Ring of Fire?
100
When two plates slide past each other which can form faults like the one in California.
What are transform boundaries?
100
when two plates slide past each other and one of them gets stuck. When the one plate frees itself rapidly, stresses the plates causing this type of geohazard.
What is an earthquake?
100
When two plates in the ocean collide together but one of the plates submerges under another one and creates subduction zones.
What are oceanic-oceanic collision?
100
250 million years ago, all the continents in the world today came together to form a supercontinent.
What is Pangaea?
200
The volcano in the Yellowstone National Park that provides heat to the geysers and responsible for a large scale of volcanism in Oregon, Nevada, Idaho, and Wyoming .
What is the Caldera Hotspot volcano? ( Yellowstone Hotspot)
200
When two plates move towards each other which can cause mountain or volcano formation.
What are convergent boundaries?
200
When two plates converge and one submerges under the other but then gets stuck. When released, a lot of pressure is released form the mantle causing magma to come out of the crust.
What are volcanic eruptions or volcanoes?
200
When two types of plates converge together on land to form mountains. E.g. Himalayas.
What are Continental- Continental plates.
200
A scientist that discovered that the coastlines of Africa and South America were the same.
Who is Alfred Wegener?
300
When a two plates start to diverge and lava comes up and cools. It is also a submarine mountain chain in the central Atlantic, was discovered.
What is a Mid-Atlantic Ridge?
300
When two plates start to move away from each other.
What are divergent boundaries?
300
When is there is a movement of soil and rock down a slope. These often happen because of earthquakes, volcanic eruptions and floods (rainfall).
What are landslides?
300
When an oceanic plates goes under or subducts under a continental plate. E.g. The Andres
What are Subduction Zones?
300
In this geologic era, the northern continents joined in to Laurasia and the southern continents joined into Gondwanaland.
What is the Triassic era?
400
When the Indian plate and the Asian plate collides together but not one of the plates go under each other.
What makes the Himalayan Mountains?
400
When two plates start to move towards each other but one plate submerges under the other plate.
What are Subduction Zones?
400
When two oceanic plates are in a transform boundary movement and one plate gets itself free from being stuck yet causing a underwater earthquake.
What is a tsunami?
400
When two plates come together and one plate submerges under the other to make subduction zones.
What are Continental-Oceanic collision?
400
Right now, this type of boundary is pushing us west making the Atlantic bigger.
What is the divergent boundary?
500
When the subducting plate is bent downward to form a very deep depression in the ocean floor. This type of feature is off the coast of the Philippines.
What is Mariana Trench?
500
When the convection currents in the mantle helps move the plates away from each other which makes a gap that is filled with water.
What are rift valleys?
500
When the beginning of volcano's eruption quickly melts snow and ice on a volcano or moving water from a crater lake. It can also be formed by heavy rainfall during or after an eruption, when volcanic ash is washed off the volcano.
What are lahars?
500
The Mariana Trench, a geological feature, is found on this type of convergent boundary.
What are oceanic-oceanic collision?
500
In 250 million years, all the continents would once again collide together and form another supercontinent that is not exactly pangea.
