Africa is very poor continent though it is very rich in natural resources because of, food scarcity, not having access to healthcare, graft in the government and inadequate facilities etc.
Africa is the second-largest and second-most populous continent in the world, both rankings going to Asia. It occupies 20% of the planet's land area and around 30.3 million km2 (11.7 million square miles) of the planet's total surface area.
Despite having a variety of natural resources, Africa is the second-least rich continent overall, behind Oceania, and the least wealthy per person. Numerous variables, such as geography, climate, tribalism, colonialism, the Cold War, neocolonialism, a lack of democracy, and corruption, have been suggested as causes by academics. [11] Despite this low wealth concentration, Africa remains a significant economic market in the larger global context due to its recent economic growth and its sizable and youthful population.

To generate lightning, a cloud must have a ____ charge in the top half of the cloud and a _____ charge in the bottom half of the cloud.
To generate lightning, a cloud must have a positive charge in the top half of the cloud and a negative charge in the bottom half of the cloud.
A natural discharge called lightning occurs when the charge in various parts of the atmosphere is balanced. This generates lightning, an incredibly deadly kind of energy that moves exceedingly quickly. Lightning produces a shockwave, and thunder is produced from that shockwave. When a negatively charged cloud encounters a positively charged cloud, opposites attract and lightning results. Evidently, these don't hit the ground. Simply said, they go from cloud to cloud.
Three forms of lightning are frequently observed: cloud to ground, cloud to cloud, and cloud to air. Thunder is a sound produced by a shock wave created by lightning, which is created when the pressure of gases nearby suddenly rises. Lightning frequently happens during thunderstorms and other intense weather systems, but it may also happen during volcanic eruptions.

Stream valleys are produced through combined effects of mass wasting and running water. If running water alone were responsible for creating stream valleys, how would they appear?.
If running water alone were responsible for creating stream valleys, they appear because of narrow valleys with vertical walls.
A valley is an extended low area that frequently stretches between hills or mountains and usually has a river or stream that flows from end to end. Most valleys are created by rivers or streams eroding the surface of the ground over a very long period of time. Some valleys develop as a result of glacial ice erosion. The valleys in high mountainous or arctic regions may still have these glaciers. These glacially formed valleys at lower latitudes and altitudes may have been constructed or increased during ice ages, but they are presently ice-free and filled with streams or rivers. Valleys may be completely dry in desert regions or only sometimes carry a river. Dry valleys may also occur from drainage in limestone-bearing areas.

The effort to protect the environment of a region in South America is a vital task that requires the collaboration and cooperation of local communities, government agencies, and conservation organizations.
How to illustrate the essay?One example of such an effort is the creation of protected areas, such as national parks and reserves, to safeguard the region's unique biodiversity and ecosystem services. These protected areas not only conserve the natural resources but also provide opportunities for sustainable tourism, which can generate income for local communities and support conservation efforts.
Another important aspect of environmental protection in South America is the reduction of deforestation and habitat loss. This can be achieved through sustainable land use practices, such as agroforestry and reforestation, as well as through the enforcement of laws and regulations that prohibit illegal logging and land clearance. Additionally, efforts should be made to promote the use of renewable energy sources, such as solar and wind power, to reduce the dependence on fossil fuels and mitigate the impacts of climate change on the region.

There is a 4-minute difference in time for each degree of longitude. As a result, if it is 12 o'clock at Greenwich (0 degree), it will be 12 o'clock at 1 o'clock meridian, and so forth.
What conversion best for degree of longitude into time?90 degrees of longitude separate Greenwich and New Orleans. Total time difference is equal to 90 × 4 = 360 minutes, or 360 × 60 = 6 hours. The local time in New Orleans is six hours earlier than in Greenwich, or six o'clock in the morning.

estimate the change in surface area of the torus when r changes from r to r and r changes from r to r.
Using the concepts of torus, we got that 241.264cm² is the change in change in surface area of the torus when r changes from r to r and r changes from r to r
We know very well that surface area of torus is given by 4π²(R²-r²) where R is the radius of the outer shell and r is the radius of the inner shell.
We are given that initial value of inner radius (r)=3.00,
final value of initial radius (r)=3.05.
initial value of outer radius (R)=5.50,
and final value of outer radius(R)=5.65
Therefore, according to the formula,
Initial surface area of the torus=4π²(R²-r²)
On putting the value of R and r,
=>S₁=4π²[(5.05)²-(3.00)²]
=>S₁=4×3.14×3.14×[25.5025-9]
=>S₁= 39.4384×16.5025
=>S₁=650.8321cm²
Similarly, for final surface area of torus
=>S₂=4π²[(5.65)²-(3.05)²]
=>S₂=4×3.14×3.14×[31.9225-9.3025]
=>S₂= 39.4384×22.62
=>S₂=892.09cm²
So, the change in surface area(ΔA)=S₂-S₁
=>ΔA=892.09-650.8321
=>ΔA=241.264cm²,
Hence, the change in surface area of the torus when r changes from r to r and r changes from r to r is 241.264cm²
