The most commonly used method of moving people and goods in Central Africa is by vehicles that can passed through roads. Most of the interior parts of Central Africa are wet terrain. This is the reason why roads are not paved in most of its areas because during wet season some roads become impassable and muddy. This then complicates transportation for many dwellers in the land.
The answer is B because the lava cools and hardens into the new rock
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.
Answer:
E. the troposphere has a homogenous composition of all gasses and vapors including water.
Explanation:
- The troposphere being a region of mixing is the homogenous composition of gases and water vapor that can be found in abundance in this layer above the surface of the earth.
- It is the stage for 99% of all the weather phenomenon and is well defined from the equator to poles. It is less dense near the equator and denser near the poles.
- About 75 % of the atmosphere is found below this layer above which lies the tropopause where the mixing stops and no changes in temperature at this layer. The layer extends from 0 to 20 kilometers in height.
- Apart from this dust particles are also found in this layer of the atmosphere.
