Millet is grown in the Sahel because it is one of the main staples of the people there. Also, when grown with cowpea and sorghum, the risk of complete crop failure is greatly reduce
Answer:
B. The presence of an earthquake belt.
Explanation:
A rift valley only happens when the plates are diverging. A trench represents plates converging. And the presence of active volcanoes is only on converging and some diverging boundaries (hence there is no volcanoes in California). An earthquake is present in all plate boundaries.
we cannot survive without oceans.
The Earth's tilt is causing change of seasons on the latitudes north and south from 23 degrees, mostly being manifested in four different seasons.
Explanation:
The tilt of the Earth is a major factor that contributes to the occurrence of seasons in some parts of the planet. The tilt is roughly 23 degrees, and it half of the year it makes the Northern Hemisphere to be more exposed to the Sun, while in other half of the year it makes the Southern Hemisphere to be more exposed to the Sun. This results in changes of seasons throughout the year.
When the Northern Hemisphere is tilted toward the Sun, it experiences summer. During the summer, the North Pole experiences constant daylight because it is constantly exposed to sunlight. When the Northern Hemisphere is tilted away from the Sun, then it experiences winter, and the North Pole has constant night because it is to exposed to the Sun at all.
The transitional period between the winter and the summer is the spring, where the sunlight and temperatures gradually increase. The transitional period between the summer and the winter is the autumn, where the sunlight and temperatures gradually decrease. This is the same on the Southern Hemisphere as well, just in the opposite part of the year.
There are four stages that mark the seasons:
- spring equinox
- summer solstice
- autumn equinox
- winter solstice

Answer:
Rivers transport particles, from fine ones such as silt in turbid water to coarser ones such as sand, gravel, and boulders associated with bed-load transport. The speed and turbulence of currents enable transportation of these materials. When riverbed gradient or the river flow diminishes, particles tend to drop out.
