Week 4 Flashcards
(12 cards)
A geological formation formed due to various geological processes like opposition and movement of tectonic plates. What is it?
Mountain
A geological formation formed around a vent that allows to reach the surface of the earth. What is it?
Volcano
A volcano has three types. Namely, these are:
Composite/strato
Sheild
Dome
A type of volcano where towering peaks which rise hundreds to several thousand meters above their surroundings
Strato/composite
A type of volcano where it’s a broad domed volcano, has gently sloping sides and has characteristics of the eruption of fluid basaltic lava. What is it?
Sheild
A convergent plate boundary where when two plates collide, they have a density lower than the mantle which prevent subduction. It creates mountains. What is it?
Continental-continental convergent plate
A convergent plate boundary where one of the plates is pushed, subducted, under the other that mixes with the overlaying mantle. The water to the hot mantle lowers the crust’s melting point that leads the formation of magma. What is it?
Oceanic-oceanic
A type of volcano where it is formed when lava reaching the Earth’s surface is so viscous. It cannot flow away readily and accumulates around the vent. What is it?
Dome
This action occurs when convergent plate boundaries with two tectonic plates collide towards each other, one plate eventually slides beneath the other. What is it?
Subduction
It will cause the formation of trenches and will eventually reach the mantle causing it to melt and turn into magma. What is it?
Converging oceanic plates
What are the three types of convergent plates boundaries?
Oceanic-oceanic
Continental-continental
Oceanic-continental
A type of convergent plate boundary where one plate is oceanic, there are large volcanoes found in lines that outline the subduction zone.
Oceanic-continental
