Answer:
There will be no solution for the question.
Explanation:
Assume;
Smaller number = x
Larger number = y
So,
2x = y
and
x - y/2 = 20
So,
y = 2x
x - y/2 = 20
If we put y = 2x
x - x = 20
There will be no solution for the question.
No one would have laws to abide by and no guidance for rules
Answer:
B - They needed access to bodies of water for trade.
Explanation:
Sub Saharan African cities are endowed with resources. These resources have been a major source of their living and survival. The abundant resources necessitate them to trade and exchange these resources even beyond there geographical boundaries. With the presence of water, it is thus easy to trade and cross materials beyond their borders. Water is life. It is also a means of transportation. This thus facilitate the marketing and exchange of resources among the sub Saharan region.
Answer:
Africa appears much bigger than the other landmasses on the Peters map projection.
Explanation:
There are numerous projection maps. All of them have some advantages and some disadvantages. One of those map projections in the Peters map projection or Gal-Peters map projection. This map projection's biggest problem is that it stretches certain parts of the world, some horizontally, some vertically.
On this map projection, Africa looks much bigger than it is, and it is comparable with the size of Asia even though Asia is much bigger in reality. The reason for this is that on the Peters map projection a vertical stretching occurrs around the Equator, and since the Equator passes around the middle of Africa the effect is the biggest at this landmass.
Answer:
Explanation:
Weathering is a natural process of break down of rocks or minerals into sub-parts, sediments and others. The two broad categories of weathering which are responsible for breaking down of rock/minerals are:
1. Physical and mechanical weathering: It refers to the process by which the rocks are broken down into sub-parts. This process does not alter the chemical composition of the rocks. The agents such as temperature, pressure, and others.
2. Chemical weathering: It refers to the process by which the rocks are subjected to chemical treatment such as hydrolysis, oxidation, and carbonation. These treatments brings change in the chemical composition of the rocks which further causes the disintegration of rocks.
