How do tectonic plates cause earthquakes and volcanoes?
Plates sliding past each other cause friction and heat. Subducting plates melt into the mantle, and diverging plates create new crust material. Subducting plates, where one tectonic plate is being driven under another, are associated with volcanoes and earthquakes.
1
How do tectonic plates affect us?
Tectonic plates have no effect on Earth itself. However, they do affect living things on Earth. Earthquakes and volcanic eruptions happen because of plate tectonics moving constantly. They are moved by convection currents emanating from deep in the mantle.
2
What are some factors that affect the amount of damage done by an earthquake?
When we discussed earthquake intensity we discussed some of the basic factors that affect the amplitude and duration of shaking produced by an earthquake (earthquake size, distance from fault, site and regional geology, etc.) and as you are aware, the shaking caused by seismic waves can cause damage buildings or cause
3
Which plate boundary has the strongest earthquakes?
At convergent plate boundaries, where two continental plates collide earthquakes are deep and also very powerful. In general, the deepest and the most powerful earthquakes occur at plate collision (or subduction) zones at convergent plate boundaries.
4
What is the relationship between earthquakes and volcanoes?
Some, but not all, earthquakes are related to volcanoes. For example, most earthquakes are along the edges of tectonic plates. This is where most volcanoes are too. However, most earthquakes are caused by the interaction of the plates not the movement of magma .
5
What type of tectonic plates cause earthquakes?
Plates move towards one another at convergent boundaries; one plate is forced below another in a process called subduction. Earthquakes and composite volcanoes are common at this type of boundary. Plates move past on another at transform boundaries.
6
What is the most studied fault in the world?
A smaller number of transform faults cut continental lithosphere. The most famous example of this is the San Andreas Fault Zone of western North America. The San Andreas connects a divergent boundary in the Gulf of California with the Cascadia subduction zone.

What are some natural disasters that can be caused by tectonic plates?
Transcript of Tectonic Plates and Natural Disasters! A natural disaster is a major event caused from a natural processes of the Earth, some examples include floods, volcanic eruptions, earthquakes and tsunamis.
8
What are fault lines and in what ways do the plates move at the faults?
Reverse faults, also called thrust faults, slide one block of crust on top of another. These faults are commonly found in collisions zones, where tectonic plates push up mountain ranges such as the Himalayas and the Rocky Mountains. All faults are related to the movement of Earth's tectonic plates.

How does the movement of tectonic plates cause earthquakes and volcanoes?
Plates sliding past each other cause friction and heat. Subducting plates melt into the mantle, and diverging plates create new crust material. Subducting plates, where one tectonic plate is being driven under another, are associated with volcanoes and earthquakes.
10
What is the link between earthquakes and the movement of tectonic plates?
Tectonic Plates, Earthquakes, and Volcanoes. According to the theory of plate tectonics, Earth is an active planet. Its surface is composed of many individual plates that move and interact, constantly changing and reshaping Earth's outer layer. Volcanoes and earthquakes both result from the movement of tectonic plates.
11
How do the tectonic plates move?
Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. Tectonic Plate is a piece of crust and uppermost mantle of Earth.
12
What is the distribution of earthquakes?
Plate tectonics cause earthquakes and volcanoes. The point where two plates meet is called a plate boundary. Earthquakes and volcanoes are most likely to occur either on or near plate boundaries. The map shows the world's tectonic plates and the distribution of earthquakes and volcanoes.
13
How do the plates move where convection currents are sinking?
Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
14
Where do most of the world's earthquakes and volcanoes occur?
At diverging plate boundaries, earthquakes occur as the plates pull away from each other. Volcanoes also form as magma rises upward from the underlying mantle along the gap between the two plates. We almost never see these volcanoes, because most of them are located on the sea floor.
15
How a convection current is created?
The liquid or gas in hot areas is less dense than the liquid or gas in cold areas, so it rises into the cold areas. The denser cold liquid or gas falls into the warm areas. In this way, convection currents that transfer heat from place to place are set up.
16
How do earthquakes happen?
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. When the rocks break, the earthquake occurs.
17
What plate boundary causes mountains?
Thus at divergent boundaries, oceanic crust, made of basalt, is created. When two plates come together, it is known as a convergent boundary. The impact of the two colliding plates buckles the edge of one or both plates up into a rugged mountain range, and sometimes bends the other down into a deep seafloor trench.
18
How do volcanoes form at hotspots and create islands?
The Earth's outer crust is made up of a series of tectonic plates that move over the surface of the planet. In areas where the plates come together, sometimes volcanoes will form. Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the seafloor, at what is called a “hot spot.”
19
How do tectonic plates cause volcanoes to erupt?
Under the right conditions, when plates are pushed together or pulled apart, volcanoes are created, which is why they tend to occur in the same place as earthquakes. When tectonic plates spread apart from each other, hot magma rises up and fills the space between.
20
Do earthquakes occur at divergent plate boundaries?
Earthquakes are located along the normal faults that form the sides of the rift or beneath the floor of the rift. Divergent faults and rift valleys within a continental mass also host shallow-focus earthquakes. Shallow-focus earthquakes occur along transform boundaries where two plates move past each other.
