Answer:
Why the majority of species live on earth and not in the sea is one of the top questions of science. The following are some of the reasons some scientists quote:
- plants play a major role; plants need light for photosyntesis, there is little sun in the ocean except for shallow coastal areas; so, land is more productive than the cold, dark depths of the ocean;
- the co-evolution of plants and insects has also played a role in the birth of so many new species; the vast majority of plants on Earth are flowering plants and 80 percent of all species are insects.

Explanation:
Geothermal energy is the energy drawn from the earth (geo) by way of the hot rocks that are found there. It is created as a result of the tremendous heating caused by the fission of radioactive elements in the earth's core.
Nobody has even gotten close to directly examining the interior of the Earth. So there is disagreement among geophysicists as to how heated the Earth's core is. However, the speed at which earthquake waves, sometimes known as "seismic waves," move can reveal a lot to scientists about the composition of the Earth.
It is thought that the Earth's core temperature ranges between 5,000 to 7,000 degrees Celsius. That is far colder than the sun's inside, yet roughly as heated as the sun's surface.

Answer:
The correct answer is C. Most Inca cities were located along the main roads.
Explanation:
The Inca Empire Road System was the extensive and advanced road network of the Inca Empire that collapsed in the 16th century in western South America, between the Andes Mountains and the Pacific Coast. There were a total of 40,000 kilometers of roads in the network.
The Incas built it centuries before the Spanish conquest. The network was partly based on pre-Inca roads. The network grew to its fullest size in the 15th century after the Inca Empire had reached its largest size.
The road network connected the villages and towns of the vast Inca Empire, which therefore were located along the main roads. There were a total of 40,000 kilometers of roads on the Inca Empire Road System. It had two north-south main roads: the coastal highway and the mountain highway. There were inns every 20 kilometers; some of them were fortifications with military supplies.
Doldrum is the region of very calm and little or no wind on either side of the equator. Doldrums which is also called convergence zone is an equatorial region of the Atlantic ocean which has sudden storms and light unppredictable winds. In addition doldrum is abelt around the earth near the equator where the sailing ships sometimes get stuck on windless water.
