Compare Africa's wealth to the rest of the world.
Answer:
Africa is blessed with a rich bounty of natural resources. The continent holds around 30% of the world's known mineral reserves. These include cobalt, uranium, diamonds and gold, as well as significant oil and gas reserves.
Over the period 2000 to 2008 resource extraction contributed more that 30 percent of Africa's GDP, while the annual flow of foreign direct has investment into Africa increased from $9 billion to $62 billion.
Africa has been drawn a little benefit from this mineral wealth and remains one the poorest continents on the globe, with almost fifty per cent of the population living on less than $1.25 per day.

Hot water deep within the Earth can dissolve minerals and transport them somewhere else.
What type of rock is formed by heat and pressure?When rocks are exposed to high heat, high pressure, hot mineral-rich fluids, or, more typically, any combination of these variables, metamorphic rocks develop. Such conditions can be found deep within the earth.
Deep inside the Earth, hot water runs through fractures, where it may dissolve various compounds. When boiling water rushes to the surface, it cools and crystallizes. Hot water dissolves minerals more effectively than cold water.
The rock is dragged down by motions in the earth's crust and becomes increasingly heated as it descends. It requires temperatures ranging from 600 to 1,300 degrees Celsius (1,100 to 2,400 degrees Fahrenheit) to melt a rock, transforming it into lava.
Therefore, Minerals can be dissolved and transported by hot water deep beneath the Earth.

Why was John's baptism of Jesus different from his baptism of other people? Answer using complete sentences.
Answer:
Jesus was holy and Jesus is the son of God, and when Jesus was baptized the heaven opened and Holy Spirit came from heaven in the form of a dove. And when heaven opened God said, “This is my own dear son with whom I am pleased.”
Explanation:
Answer:
It is completely impossible for Jesus to be baptized for forgiveness for sin when he can't sin. Most other baptisms are to become a new person in Christ, so Christ can't be a new person in himself. God is new and old and he knows beginning and end.

Which statement about the potential for the wind power compared to solar power in North America is most accurate based on these maps
Hello. You did not present the map to which this question refers, which makes it impossible for it to be answered accurately. However, I will try to help you in the best possible way.
Among the three countries that make up North America, we can say that the USA is the one that has the greatest potential to produce solar energy, being the third country that most produces this type of energy in the world. Mexico also has great potential, both in wind energy and solar energy, but it does not produce as much as the United States. Canada, in turn, has a greater potential for wind energy, although solar energy is also produced, but on a smaller scale.
Answer:
wind power and solar power have about the same potential.

Answer:
I. A pasture land is a land covered with grass and other low plants suitable for grazing animals.
IV. St. Mary’s Bay has filled up with water now due to some reasons and cannot be used as a farm land anymore.
Explanation:
Yes, pasture lands refers to those lands where grasses and other small plants are grown in order to used it for the feed of animals. These lands can not be used for farming of crops due to hilly area where small layer of soil is present and below that layer rock layer started so only grasses can grow over there. St. Mary’s Bay has filled up with water and not suitable for farming of crops.

4. 365.25 days for Earth to orbit the Sun — a solar year. We usually round the days in a calendar year to 365. ... But approximately every four years, February has 29 days instead of 28. So, there are 366 days in the year. This is called a leap year.
What is the primary cause for continental drift, earthquakes, and volcanic eruptions?
Question 2 options:
a.heat from the Earth's core
b.rotation on the Earth's axis
c.convection currents in the mantle
d.erosion of the Earth's crust
Answer:
Heat from the earth's core
Explanation:
The force that causes most of the plate movement is thermal convection, where heat from the Earth's interior causes currents of hot rising magma and cooler sinking magma to flow, moving the plates of the crust along with them. In ridge push and slab pull, gravity is acting on the plate to cause the movement.
