When two plates are colliding this type of boundary is formed.
What is Convergent
100
How created the Theory of Plate Tectonics?
Who is, Alfred Wegner.
100
What causes of volcanic eruptions?
Where plates move away from each other at spreading or divergent plate margins.
100
What causes earthquakes to occur?
When rock underground suddenly breaks along a fault.
100
Are there any volcanoes located in the State of Maine
no
200
When two tectonic plates are pulled away from each other, this is called?
What is a divergent plate boundary
200
What does the theory of Plate Tectonics state?
What is , At one point the continents were one giant super continent before separating and moving to the current location.
200
how often and where do volcanoes generally occur?
Active volcanoes generally occur close to the major tectonic plate boundaries. many are along the earths plate.
200
how often and where do earthquakes generally occur?
Earthquakes can also occur far from the edges of plates, along faults.
200
where is the heaviest concentration volcanoes located.
What is South Pacific ocean 600 miles of North west of easter island?
300
Define, plate boundary.
What is where two plates meet each other.
300
What is some evidence for the Theory of Plate Tectonics?
What is 1) The Continents fit together like puzzle pieces 2) similar fossils and different continents.
300
How are volcanoes monitored?
The USGS Volcano Hazards Program monitors volcanoes.
300
How are earthquakes monitored?
Seismology uses a similar principle to map the structure of rocks beneath the Earths surface.
300
what type of landmasses are volcanoes known to create.
What is landmass without forest or grass covered with magma or of a kind of rock?
400
What is it called when two tectonic plates move past each other while in contact?
What is a Strike-Slip Boundary
400
What is Theory Sea Floor Spreading?
What is, Mid ocean ridges creating new oceanic crust through volcanic activity. Causing the old crust to be pushed.
400
what can people do to reduce the risk/damage from volcanic eruptions?
Build a trench and a lot of water.
400
What can people do to reduce the risk/damage from Earthquakes?
What is an earthquake proof building or a strongly built structure?
400
what does volcanic soil consist of?
volcanic soil is great for agricultural products. It is very fertile and holds water, that is why people live by volcanoes.
500
When plate boundaries move, what often occurs
What is earthquakes?
500
Who created the Theory of Sea Floor Spreading?
What is Alfred Wegener
500
What is the effect of volcanoes on other earth systems?
Volcanoes effect the atmosphere by volcanic eruptions releasing lots of gases into the atmospheric.
500
What is the effect of earthquakes on other earth systems?
What is a tsunami or a tidal wave
500
What is the distribution of volcanoes in the United States
Most of the volcanoes in the United States are located in the Western part of the country. California has roughly 20 volcanoes. New Hampshire has two volcanoes but again most are in the western part. The state with the most volcanoes is Oregon with exactly 43 volcanoes.
