What causes volcanoes in the Aleutian Islands?
The volcanoes that formed the Aleutian Islands are the result of a process called subduction. The Pacfic Plate is sliding or subducting under the northern part of the North American Plate at about 3 inches per year. As this oceanic plate dives into the mantle it takes some seawater with it. The water seeps into the hot rocks of the mantle, lowering the melting point. The resulting molten rock or mantle then rises through the North American Plate then erupts through the North American Plate, forming volcanoes.
What type of plate boundary is California?
The Pacific plate is on the left and The North American plate is on the right. The Pacific plate is moving in a northwesterly direction while the North American plate is moving Southwest This is a conservative plate boundary where pressure is being built up and at any point one plate can jerk and release all this energy in the form of shockwaves.
How far out from pitching plate should the circle be?
There is a 16 foot circle with the pitching plate as the center point.
Is Mexico Central American?
It lies on the North American tectonic plate and is considered by most Mexicans to be a North American country. However, most Spanish-speaking countries of Central America consider Mexico like one of them. It really depends on your point of view.
What center point from which all meridans begin and which is the north extremity of the earth's axis?
The North Pole is the center point from which all meridians begin and it is the north extremity of the Earth's axis.
What is the easternmost point on the north American continent?
The easternmost point on the North American continent is Cape Spear in Newfoundland, Canada. It is also the easternmost point in North America.
Are there any possibilities of having 3 or more tectonic plates meeting at a point to form a kind of multiple plates boundary?
The point where three different tectonic plates meet is known as a triple junction. One famous example is the Mendocino Triple Junction where the Pacific Plate, the North American Plate and the Gorda Plate meet.
If you are on the center of the north or southpole what does a kompas do then?
It will point to magnetic north, which is hundreds of miles from the pole.
What is the plate boundary of the san Andreas fault?
A transform boundary.
Is Europe a continent in north Africa?
No. Europe is on the Eurasian continental plate (along with most of Russia, and China), and Africa is on the African continental plate. Some of Russia is on the North American plate, and India is on its own continental plate, which is why it's called the Indian sub-continent - the Himalayas are being thrown up at about 6cm a year at the point where the Indian plate is crashing into the Eurasian plate. In mapping terms, plates do not strictly translate to continents, so all of Russia and Siberia is geographically on the continental land mass of Europe, even though physically half of it is on the North American plate (the land masses are separated by the Bering Strait). http://en.wikipedia.org/wiki/File:Plates_tect2_en.svg
Where is the center of the northern hemisphere located?
The geographic center of the northern hemisphere is in the Arctic Ocean, at approximately 84° longitude and 13.5° latitude, which is near the North Pole. This point is the halfway point between the equator and the North Pole, dividing the northern hemisphere into two equal halves.
What point is at the center of Northern hemisphere?
The geographic North Pole, located at 90 degrees North latitude, is at the center of the Northern Hemisphere.
