Natali [406]2 years ago

It is expected that seafloor samples taken farther from land usually contain a greater proportion of biogenous sediments because sediments are thinnest on the seabed closest to spreading centres (young seafloor) and thicker distant from the ridge (older seafloor with more time for accumulation). Additionally, sediments are substantially thicker close to continents.

More about seafloor sediments:

Terrigenous, pelagic, and hydrogenous sediment are the three different types of sea floor sediment. Terrigenous sediment is deposited on the continental shelf, continental rise, and abyssal plain and is derived from the land.

Clay particles and tiny marine animal skeletons that progressively sink to the ocean floor make up pelagic sediment. Minerals that precipitate from seawater on the ocean floor, such as manganese nodules, are abundant in hydrogenous sediments.

Because one million children were orphaned, child-headed households were a result of the genocide
Maksim231197 [3]
I think your question is: after which Genocide was this the case?

It might have been more than one genocide, but it was definitely the case in the Rwandan Genocide. Specifically it is estimated that around 100 000 children live in such households. (but his data is from 2003, so in the meantime those children grew up)

Why is the equator region not the hottest despite vertical sun rays?​
ohaa [14]

Answer:

Because the equator is not pointed directly toward the sun because of the earth's inclination, which is around 23 degrees. The area that is the warmest in either summer or winter is 23 degrees north or south of the equator. The equator is at its warmest during the start of spring and in the fall. The hot spot oscillates up and down as a sinus wave with a one-year duration. Deserts may be found in the hottest parts of summer and winter, which are furthest from the equator. Less variance exists towards the equator, creating a tropical climate. Never too chilly or too hot.

<h2>Why is it that when you get closer to the equator of the earth you have deserts, but at the equator you have rainforests, isn't it hottest at the equator?</h2>

Due to shear forces created by the nearly spherical shape of the Earth, the equator's surface spins more quickly than that of more northerly or southerly latitudes. As a result, the air generally rotates counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. Consequently, moisture-laden air is brought in from over the equatorial sections of the seas and forced to travel over the equatorial land masses where it deposits its moisture, especially on higher terrain. This causes air from the equator to be driven north and south. This region of the country will receive very little rain since by the time the air reaches the tropics, it is virtually dry. The tropical waters evaporate a lot because they are so warm. The flow of the air is distorted by the configuration of land masses and other seas, and numerous eddies emerge in the north and south where other complex weather systems are dominant. In these areas, jet streams are in charge of the weather. Antarctica is extremely dry since the majority of its water is frozen, and in certain areas snow or rain are so seldom that all that is left is bare dry rock.
