100
Say examples of evidences of the internal energy.
Geysers, volcanos, earthquakes
100
According to the compositional model say the layers that we can find
Crust, mantle, core
100
What are the tectonic or litospheric plates?
100
Explain the differences between magma and lava
100
What is an earthquake? Epicentre/hipocentre?
is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
200
What is a geyser?
A jet of steam that comes up
200
According to the dynamical model say the layers that we can find
Litosphere, astenosphere, mantle, layer D core
200
Say the name of the main type of boundaries among plates
Divergent, convergent, transform boundaries
200
Parts of a volcano
200
What are the seismic waves? Whay types are there?
is an elastic wave generated by an impulse such as an earthquake
300
Where can we find most of the volcanos/earthquakes?
In the tectonic boundaries
300
Is there any layer in the liquid state? Why is the inner core solid?
The outer core.
Because there is too much pressure in the inner core, it can´t melt.
300
What are the mid-ocean ridges? And the ocean faults?
300
Type of volcanic products
300
Say the main earthquakes hazards
400
What is the ring of fire? Where is it?
The place where most volcanos and earthquakes happen. In the pacific ocean
400
Say differences between the continental and oceanic litosphere
The continental litosphere is thicker and less dense
The oceanic litosphere is more dense and thinner
400
What causes the movement of the tectonic plates?
400
Which are the main volcanic hazards or dangers?
400
Say the main differences between P and S waves
P waves are faster and can travel through solid and liquid materials
S waves are slower and can only pass through solid materials
500
Where comes from the internal energy of the Earth?
Heat that remains from the moment the Earth was formed.
Desintegration of radiactive atoms
500
What is the litosphere?
The crust and the uppermost part of the mantle
500
Describe each type of boundary (type of movement, phenomenons associated...and an example of two plates with this type of boundary)
500
What are the different types of volcanic eruptions? What causes them? What are the main differences among them?
500
How can seismic waves help us study the geosphere?
