The answer is true. They have maps that can map where mines are and things like that.
The answers are as follow:
7. A.
The Africa continent is richly bless with all kind of mineral resources in high quantities. Different minerals can be found in various African countries in varied quantities. Out of all these mineral resources, the ones which African has in rich quantities include diamond, gold and oil. The African continent provides 46% of the world diamond and 21% of the world gold. The continent is also rich in oil.
8. B
Government revenue refers to those money which the government generate; government uses this money to cater for the public and their needs. The amount of revenue to be spent on different categories of needs are usually determine at the beginning of every fiscal year. African governments typically devote a small percentage of their revenue to interest payment.
9. B
Despite the rich mineral resources which are found on the African continent, the continent is a very poor one due majorly to corruption and lack of efficient management of resources. The countries in the south of Africa seems to be better off financially that those in the sub Saharan part of Africa.
The two gasses in the troposphere that play vital role in heat absorption are the water vapor and the carbon dioxide. Both of them are gasses that trap both part of the solar heating, and part of the Earth's heating, and they play a vital role in the regulation of the temperature on the Earth with the process better known as ''Greenhouse effect''.
Answer:
here as you had already done it in the pic which is also right i.e we will reach in second quadrant
Answer:
Water from rivers erodes the banks, the ice breaks up rocks, intense rainfall causes mass wasting, water from rainfall flows as runoff and creates ripples.
Explanation:
Earth has several spheres, all of which have their own unique characteristics that define them as such. Despite all of them being very different from each other, they can not exist in the form they are if there is no interaction with the other spheres, thus all of the spheres are interconnected and they depend on one another.
Two of those hydrospheres are the hydrosphere and geosphere, and they interact in many different ways. When there is rainfall, the water that ends on land flows as runoff until it reaches a water body, and while it does so it manages to create ripples in the ground. If there is intense rainfall in an area where there is steep and unstable terrain, it can easily cause mass wasting by oversaturating the soil with water. The water that flows in the rivers with its power is constantly eroding the banks. If water freezes and turns to ice because its volume becomes greater, it is able to break up rocks with the pressure it creates on them.
