Explain the impact of desertification on the environment of Africa from the sahel to the rainforest?
Desertification in Africa, spanning from the Sahel to the rainforest region, leads to the degradation of fertile land, loss of biodiversity, and displacement of communities. It results in soil erosion, reduced agricultural productivity, and increased vulnerability to droughts and floods. This trend can exacerbate poverty, food insecurity, and conflict in affected areas.
Is Hawaii made up of eight islands?
Island arcs are formed by the subduction of an oceanic plate beneath another oceanic plate. The oceanic plate that is subducted beneath the other plate melts as it is pushed down into the mantle and creates a source of magma. The magma rises and forms volcanoes which create the islands of the island arc. The Hawaiian islands are formed by a mantle plume which is roughly in the center of the Pacific plate. The plate is moving across the plume and the islands are being formed in a line as the plate moves. The Hawaiian islands don't count as an island arc because they are formed in a completely different process and because they are roughly in a line, not an arc.
What determines the grain shape of a rock such as conglomerate?
The mineral composition of the conglomerate determines the grain shape as well the the type of weathering or erosive elements (wind, water, chemicals) that the rock is is exposed to because grain shape is heavily dependent upon whether the rock has been subjected to erosion or not.
When listenning the location of a place the degree of longitude is alway listed blank?
Even before filling in the blank, we can tell you that the resulting statement would be untrue.
While it may well be true that longitude is traditionally listed last, it's not a hard and fast rule,
and no harm comes from listing it first. As long as latitude and longitude are clearly identified
to avoid any confusion, they may be listed in either order.
