Biology
1 answer:
rewona [7]3 years ago

Answer:

The out of Africa theory states that Homo sapiens began in a single geographical area and spread out from there.

Explanation:

A is correct because the ''out of Africa theory'' suggests that the Homo sapiens began as a species in Africa and from there it gradually spread out on the other continents across the world.

B is not correct because the ''tectonic theory'' is a theory that has nothing to do with the Homo sapiens species, but it is a theory about the movement of tectonic plates.

C is not correct because the multi-regional theory suggests that the Homo sapiens evolved into multiple regions simultaneously, not in one region only.

What would happen if all the major mountain ranges, particularly in the north hemisphere were gone? The Rockies, Himalayas, the
mylen [45]

Answer:

These big and hefty mountain ranges are play important role in weather and wind patterns in their related geographical region. Mountain ranges such as Himalayas, Rockies and Alps affects the weather and movement of wind on global level as well.

In absence of these mountains the global pattern of the wind can be affected and cause drastic change in global climate change as they play crucial role as barrier to wind and jet streams by diverting or dividing it.

For instance Himalayas, during the northern winters diverts the wind and acts as barrier for wind which prevents it from freezing. Rockies and Andies blocks the moisture laden winds flow from Pacific Ocean to western flanks of the american continent that leads to a dry region called rain Shadow desert zone.

Hence if these mountain ranges are gone these impacts will not be felt. Similarly Himalayas in India, cause monsoon wind to strike and cause rain in the region. So winds are greatly affected by these Mountains. If these mountain ranges were gone, winds will flow undisturbed as there would be no barrier to global wind patterns.

Use the drop-down menus to identify the types of convergent boundaries labeled A, B, And C.
algol [13]
Oceanic-continental convergence occurs when an oceanic plate and a continental plate converge. They are pushed together and the oceanic plate is forced to go under the continental plate. So based on the diagram, this convergence occurred in letter B. 

Oceanic-oceanic convergence occurs when two oceanic plates collide into one another. The oceanic plate that is older, denser and/or colder will be the plate that will go under the other. It will be forced down into the mantle. So in our diagram, this occurs in letter A.

Continental-continental convergence occurs when two continental plates converge. In this case, the plates push up against each other and create mountain ranges. Unlike the other two, they do not sink down, the movement is upwards. This occurs in the area C of your diagram.
