Answer:
C. When the oceanic lithosphere, which is more dense, sinks and pulls the plate with it
Explanation:
Slab pull and other mechanisms are responsible for the motion of plates. Every tectonic plate is driven by mantle convection.
- Convection is a form of heat transfer in fluids.
- It is as a result of differences in density and temperature values.
- The oceanic crust is denser and colder.
- As hot magma from deep within the subsurface rises and move through cracks, the oceanic lithosphere is drawn down and deeper.
- This cycling between the cold lithosphere and hot rising plumes provides the mechanism that drives plate motion.
Answer:
Explanation:
Ans 1) The approximate elevation of wonderland lake is about 5500 feet, because it lies in the vicinity of the ridge where peak are having contour values upto 6600 feet and the wonderland lake lies on the lower contour of near about 5500 feet.
Ans 2) The peak elevation of poorman hill is 6485 feet as it can easily seen in the map that the highest contour value us 6485 feet. Poorman hill is lying in this contour value.
Ans 3) It is clearly seen and observed from the map that the elevation of the poorman hill is about 6485 feet where as the elevation of the boulder creek present at the south of poorman hill is less than 6000 feet. Thus poorman hill has higher elevation as compared to bank of boulder creek.
Between 1945 and 1960, three dozen new states in Asia and Africa achieved autonomy or outright independence from their European colonial rulers. There was no one process of decolonization. In some areas, it was peaceful, and orderly. In many others, independence was achieved only after a protracted revolution.
Answer:
igneous rock
Explanation:
There are three main kinds of rocks, sedimentary, metamorphic and igneous.
The igneous rocks are the ones that formed from a hot source like magma inside the soil, as it gets to the surface of the Earth it goes cooling. If it cools almost in the surface of the Earth then is consider a plutonic rock.
Plutonic Rocks have a big quantity of minerals, since they cool under a big pressure, these minerals get together forming a solid rock.
By passing the time the granites of minerals can be easily seen at naked eye, like the characteristics of these sample.
