Earth and Space Sciences - Assignment Example

The plates shown in this diagram are the Convergent Plate Boundaries – The Convergent Plate Boundary occurs when two plates, converge other. There are three ways in which a convergent plate boundary is formed. Ocean- Oceanic forms when two oceanic plates strike. The dense plate goes below the less dense one. The other two are the oceanic-continental and the continental-continental. They also occur when both plates strike each other (Tarbuck, Lutgens, & Tasa, 2014).

3.)
Granite
4.) The feature labeled "C" is a 3000-foot tall mountain with a slope angle of about 30 degrees. What type of volcano would this likely be, and what sorts of volcanic hazards might you expect to be exposed to if you lived near it?

Stratovolcano or Composite Volcano
Hazards
Toxic gases that are sometimes released from the volcano are not suitable for human existence. The inhalation of these gases could result in illnesses or even death.
The emissions could lead to an accumulation of toxic gases in the air that eventually result in acid rain.
Air eruptions present a significant hazard to pilots. The reason is once the explosion occurs, the high temperatures can melt the particles and as they change the shape of the turbine blades, they disrupt the operations of the turbine. Thus, it distracts pilots of airplanes or jets and can cause major crashes. The distraction in 1989 in Indonesia raised such an alarm.
The volcano explosion could raise the temperatures nearby. Thus, making it too hot for human survival.
In case of an explosion, it could result in deaths or injuries. The erupted solid can travel faster than the humans escape, or it could be that the fluid covered the whole area. A similar occurrence is the one in Zaire at Nyiragongo.

The solid or lava formed from the explosion could make the area unfit for agriculture. The lava dries up the area, and the land cannot be tilled.

5.)
Mount Etna in Sicily, Mount Shasta in California, Mount Hood in Oregon, and Mount Rainier in Washington all have similar characteristics as point C.

6.)
The resultant magma is intermediate.
7.)
This process is called assimilation. As the components mix in the crust, they crystallize together and then form strato volcanoes through their eruption Read More
