What is the history of Central Asia?The human occupation of Central Asia dates back to the late Pleistocene Epoch, approximately 25,000 to 35,000 years ago, but the first identifiable human groups to live there were the Cimmerians and Scythians (1st-millennium BCE) in the west and the Hsiung-nu people (from 200 BCE) in the east.

What is the biggest obstacle to traveling by boat on the Congo River?
A.
the many cataracts
B.
the unusual path of the Congo River
C.
shallow areas due to drought
D.
the river's narrow width
The biggest obstacle to traveling by boat on the Congo River is A. the many cataracts
The numerous cascades on the Congo River are the main challenge for boat passage. Navigation on the Congo River is challenging and dangerous due to a number of strong cataracts, or rapids and waterfalls. The hills and troughs in the riverbed that force the water to flow quickly across them are what generate these waterfalls.
On the Congo River, there are a total of seven major cataracts that make navigation extremely difficult and demand that boats be unloaded and portaged around. There are also shallow places brought on by the drought. Because of the ideal growing conditions provided by these shallow locations, the water plants flourished, producing troublesome obstructions for the boat.

Write a general statement that could be used to determine if other mass extinctions have occurred in Earth’s history. Explain why your statement would is appropriate. 2-3 Sentences.
Answer:
Explanation:
The most appropriate example is the extinction of the dinosaurs. All sorts of theories were put forth. Most think there was a dramatic change in the environment, a change that left no time for the dinosaurs to adapt to that change.
Whatever happened, an asteroid, volcanic eruptions, or something else, whatever you propose has to explain why birds and mammals survived.
So whatever occurred, it had to be dangerous to land animals, but not those who flew or those who could think well enough to avoid whatever was happening around them.
That said, I would propose that it was a virus that was not air born and the genetic make up of mammals could avoid the harmful effects of the virus.
I would propose that this is the only explanation that works. Perhaps the makeup of the blood could not adapt to the extinction. The blood of a dinosaur might not have included very powerful neutrophils (which fight disease).
What is the thermocline?
beneath 200 meters, ocean water cools at a constant rate of 1°C per 100 meters depth
the ocean area near the polar regions where water temperatures cool
where magma is forced up through the ocean floor along mid-ocean ridges
the area off the continental shelf that declines to the ocean floor
Answer:
Beneath 200 meters, ocean water cools at a constant rate of 1°C per 100 meters depth.
Explanation:
The thermocline is one of the three ocean zones when it comes to separating the ocean waters by temperature and weather waters mix or not. The top layer of water, or the surface water, is called the epilimnion. The second layer, or thermocline, is called metalimnion at starts from 200 meters of depth. And the last one, or deep ocean, is the hypolimnion, starting from 1,000 meters of depth.
The surface layer is the one where the water is the warmest and it mixes. In the second layer, we have the thermocline, where the water is not mixing anymore and it sharply drops in temperature. The water temperature generally drops by 1 degree Celsius per 100 meters of depth. The third layer is the coldest, but there aren't big changes in temperatures between the starting and endpoint of it.
