Mountains
During the formation of fault-block mountains, the lithosphere
stretches
An opening through which lava, rocks, and gasses erupt is called a
Volcano
Hot springs that erupt and send hot water shooting into the air are called
Geysers
Scientists monitor volcanoes to
Predict when future eruptions will occur
The Sierra Nevada Mountains are an example of
Fault-Block Mountains
Magma is made up of which two elements?
Silica & Oxygen
What does a fumarole release?
Steam and other gasses
The explosiveness of a volcanic eruption depends mostly on the
Silica
What is an example of a folded mountain?
Himalayas or Rocky Mountains
The opening of a volcano where a lava shoots out from is known as the
Caldera
Places where heated water flows to Earth’s surface is called
Hot Springs
What are some of the effects of volcanic eruptions on Earth’s atmosphere?
An increase in ash and dust
A decrease in Earth’s temperature
Acid Rain
In the formation of new mountains what is happening to the rock?
New rock is being pushed upward while older rock is being pushed down.
Ash from an ash cloud has a positive and negative effect to earth's surface. What are they?
Positive affect is that it enriches the soil.
Negative affect is that it creates majority of acid rain
Why is two parts of pyroclastic flow make is so dangerous?
Its speed and temperature
What are some positive effects of volcanoes erupting?
Volcanoes enrich the soil as well as create new land
Along which type of plate boundary are folded mountains most likely to form?
Convergent Boundary
What are the 3 types of volcanoes?
Cinder Cone
Composite
Shield
Where does the water from hot springs get its heat from?
The heat from magma in the magma chamber
If tectonic plates stopped moving, what would happen to the world?
