Answer:
Explanation:
The tectonic plates move among themselves as solid and rigid blocks, moving over the upper level of the mantle (asthenosphere).
When the plates get closer to each other, we say that they converge → ←, when they separate they diverge ← → and if what they do is move laterally next to each other they pass ⇅
In the case at hand, the Nazca oceanic plate converges with the South American continental plate, approaching each other at a rate of about 6 or 8 cm per year. And they have been doing so for at least the last 25 million years.
Since the Nazca plate, due to its composition, is denser than the South American plate, it has less buoyancy and when pushed against it, it folds and sinks towards the mantle where it melts. This process, called subduction, is responsible for the rising of the Andes, as well as the high seismicity and volcanism present along the South American west coast.
Answer:
Andes Mountains.
Explanation:
What was one consequence of the widespread disease that killed many
Native Americans?
Answer:
The pilgrims were able to stay in an abandoned village.
Explanation:
because of the disease, the pilgrims were able to stay in an abandoned village that was far away from others.
A landowner who claims title to land deposited slowly by the action of a running stream would base such a claim upon:
Answer:
claim upon accretion
Explanation:
For moment to moment, when a rights of way scheme has been examined, it is found that the actual position of the current natural border of a land being invaded is not in accordance with the position of that border displayed in the map around which the designation is centred.
Where the variance in the position of the natural growing boundaries is due to either accumulation or an wrongly defined environmental boundaries on the map around which the title is centred, a land surveyor may proceed with an application under section 118 of the Land Title Law.
Name the polar and tropical air masses that affect U.S. weather. Describe the pattern of movement across the continent and patterns of precipitation associated with warm and cold fronts.
Answer:
The answer to this question can be defined as follows:
Explanation:
In the cold surface, the air is defined by polar weather systems and relatively warm surface air masses. Its masses throughout the polar vortex are very cold.
and the 5 air masses, that impact the United States in such a normal year: continental polar, Continental Arctic, continental tropical, marine polar, maritime tropic. It influences the 5 Coastal in the USA for the continental plates, and the pattern of movement can be defined as follows:

1. Describe the change in grain size from slate to schist
2. How does the texture of phyllite differ from that of schist?
3. Why do you think that the micas (lat minerals) in these rocks are all parallel, r nearly so, to one another?
The slate is hard and fine-grained rocks and has a salty cleavage that is caused by the growth of minerals due to the metamorphose of the grain ground rocks while schist is medium grade sheet-like grain rock.
The texture of phyllite is very glittery as its a very fine grain size and the grains are flat. Schist has the greatest grain size. Phyllite has a foliated texture but schists consist of scale.Minerals like muscovite and biotite are common rocks forming minerals in micas and are found in the igneous rocks with feldspar and quartz, thus they are parallel and very finely grained flakes in the rock.Hence slate (lowest grade), phyllite, schist, gneiss (highest grade) rocks.
