It is an opening on the surface of a planet that allows material warmer than its surroundings to escape from its interior. When this material escapes, it causes an eruption
Volcano
A stage of a volcano wherein this is erupting or has shown signs that it may erupt in the near future.
Active volcano
A dead volcano; not likely to erupt again
Extinct Volcano
Also called as stratovolcano, have relatively steeper side, and symmetrical cone shape. This type of volcano is formed by alternating layers of viscous, sticky lava and ash.
Composite Volcano
Which of the following is NOT a method of heat transfer?
A.Condensation
B.Convection
C. conduction
D. radiation
Condensation
Most volcanoes are formed at the boundaries of tectonic plates_________________.
Tectonic plates
The molten rock that reaches the surface of the volcano.
Lava flow
Plates under the ocean are called __________
oceanic plates
What type of boundary is the mariana trench?
Convergent Plate boundary
What type of boundary is the san andreas fault
Transform boundary
Volcanoes are formed in ________________
subduction zones
Plates under landmasses are called_______________
continental plates
They are formed by lava flows with low viscosity. Layers of the lave build up over time
Shield volcano
A giant waves caused by earthquakes or volcanic eruptions under the sea.
Tsunami
There are three possible cases under Convergent Boundary, give two of it.
oceanic-oceanic
oceanic-continental
These are cracks on the Earth’s crust, of which there are three types.
Fault
Refers to the shaking of the Earth as a result of the breaking or shifting of the rock of the tectonic plates, which release seismic energy
Earthquake
This is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction.
Earthquake
Occur when two plates slide towards each other and form either a subduction zone or an orogenic belt
Convergent boundary
Convection currents drive the plates away from each other. TRUEor FALSE
TRUE
The plates slide against each other in opposite direction
transform boundary
An example of a composite volcano
Mount Mayon
Two plates that move away from each other create a gap or a rift between them.
Divergent boundary
Plate Tectonic is divided into two theory, which are Conrinental Drift Theory and Seafloor Theory. TRUE or FALSE.
TRUE
There are 17 large tectonic plates – seven major plates and eight minor plates. TRUE or FALSE
FALSE
