Answer:
Correct answer is False.
Explanation:
Cambrian explosion refers to period of geological history of our planet in which most of the multicellular organisms appeared in fossil layers. That was some 540 million years ago.
This period indicates that multicellular organisms began to develope in the early Paleozoic era. Before that much of the living organisms were singlecellular. Cambrian is the first period of Paleozoic era and it lasted between 540 and 485 million years ago. It is followed by Ordovician Period.
The bottom line is that Cambrian explosion is related with 'great occurrence of new and developed species'.
The correct answers are:
<em>C) glaciers;</em>
<em>D) rivers;</em>
The glaciers, with their massiveness, sheer force and weight, are able to break down both, big and small parts of the rocks, thus eroding them. Considering that the glaciers are also moving, though slowly, they are transporting the eroded material over shorter or longer distance, depending on the length of the glacier itself.
The rivers, with their force and also with their chemical composition, manage to erode the rocks little by little, and than transport the eroded sediment. The transportation distance depends on the length of the river, as well as its speed.
Answer:
C. the Gobi
Explanation:
Currently, the Gobi is the only current growing desert in China.
A fault line is the landform where a transverse boundary.
Answer:
Convection currents flow due to variations in the temperature and salinity in seawater, both of which influence its density. Variations in density in different regions of the ocean will cause water to flow from less dense areas to more dense areas as water heats up and becomes less saline, producing a horizontal convection current. Vertical convection currents can arise as cooler, more saline water sinks, causing warmer, less saline water to rise.
