Answer:
(i) Hydroelectric power is a renewable energy source as it is replenished by natural resources like the sun, unlike coal-fired power plants that generate electricity using coal which is not a renewable energy source.
(ii) It is expensive regarding the cost of building dams and reservoirs, not only that it is dependent on the amount of water available as places like the deserts would find it difficult to generate electricity all year round considering the unavailability of rain in some months of the year.
Explanation:
Hydroelectric power plants produce electricity when water energy from a water source, examples are dams and reservoirs which are caused to flow so as to turn rotors on a turbine, thereby converting this process to electricity. Coal-fired power plants are also used to produce electricity through the burning of coal (fossil fuel).
An advantage of using hydroelectric power over coal-fired power plants is that Hydroelectric power is a sustainable and renewable energy source since it is supplied by natural resources from the sun.
What is hydroelectric power?Hydroelectric power is the electricity generated by generators powered by turbines that transform the potential energy of rapidly flowing water into mechanical energy.
Hydroelectric power is a sustainable and renewable energy source since it is supplied by natural resources from the sun, as opposed to coal-fired power plants(non-renewable energy) that utilize charcoal to produce electricity.
One potential disadvantage of hydroelectric power plants is that: It is costly in terms of the expense of constructing dams, and it is also dependent on the quantity of water.

What is biome?A biome is a biogeographical unit made up of a biological community that has developed as a result of its physical surroundings and a common local climate.
Various continents may have different biomes. A biome can include a number of environments because the phrase is more general than habitat.
A microbiome is a combination of organisms that coexist in a specific location on a much smaller scale than a biome, which can encompass enormous areas.
The collection of bacteria, viruses, and other microbes found on or in human bodies is known as the human microbiome, for instance.
From local geographic scales and instantaneous temporal scales up to whole-planet and whole-timescale spatiotemporal scales, a biota is the whole collection of organisms for a place or a time. The biosphere is made up of the biotas on Earth.

The presence of greenhouse gases in Earth's atmosphere is important to Earth's ability to support human life.
How would Earth be different without greenhouse gases in its atmosphere?
A. More heat from solar radiation would escape into space.
B. More solar radiation would be reflected back into space.
c. More solar radiation would penetrate Earth's crust and mantle.
D. More beat from solar radiation would be stored in Earth's core,
The correct answer is A. More heat from solar radiation would escape into space.
Explanation
Greenhouse gases are a set of gases present in the earth's atmosphere that have the function of regulating the temperature by retaining and radiating heat energy. One of the sources of heat energy for greenhouse gases is radiation from the sun, which reaches planet Earth, passes through the atmosphere, and reaches the earth's surface where a part is reflected out of the atmosphere and another part is retained and irradiated by greenhouse gases in different directions, being retained between the atmosphere and the earth's surface, contributing to temperature regulation. Therefore, the correct answer is A. More heat from solar radiation would escape into space.

Find the volume of a pyramid with a square base, where the perimeter of the base is 4.1\text{ m}4.1 m and the height of the pyramid is 3.6\text{ m}3.6 m. Round your answer to the nearest tenth of a cubic meter.
Answer:
the answer is 1.3 m^3
Explanation:
I had a question like this and I put the answer that was shown 20.2 m^3 and I got it wrong on Delta math. And it gave me the answer after getting it wrong.
V = 1/3 B h
perimeter of base: 4.1
side length of base: 4.1/4 = 1.025
Area of base : 1.025^2 = 1.050625
B = 1.050625
h = 3.6
v = 1/3 B h
v = 1/3 ( 1.050625) ( 3.6)
v= 1.26075
rounded to the nearest tenth is 1.3 m^3

High pressure cells in the region occur in winters and replace the warm thoughts creating dry and cold weather.
What is a anticyclone that forms over Kalahari desert ?An anticyclone is opposite to a cyclone and it refers to the weather phenomenon. Defined in terms of the large scale of the winds. It moves clockwise in the north and anticlockwise south.
The anticyclone forms over the Kalahari high during the winters in the interior parts of southern Africa and forms a part of subtropical ridges. Due to which the Kalahari is a desert region.
When the eat is heated near the poles the equatorial motion force h ends upwards and as the air rises slowly it cools and subsidies near 30-degree latitude are called as Hadley cell.
Most of the economic activity of this region such as cattle rearing is affected due to the slow growth and small vegetation. The food and health of the Bantu people are impacted by dry and cold conditions.

The correct answer is C, Divides the flow of river systems in the United States into east and west.
Explanation
The continental divide is the name of the main hydrological divide in America. The divide is a mountain range that divides the eastern and western slopes. Those that are considered eastern run until they reach the Arctic and Atlantic oceans, while those that are considered western run until they reach the Pacific ocean. In the case of North America, it begins in Alaska, goes through the north of Alaska to Canada where it goes south. It continues through the western region of Canada towards the south until it reaches the United States where it crosses the states of Colorado, Montana, New Mexico, and Wyoming. Later, it reaches the Mexican territory, where it takes a central road through the middle of the country until it reaches the southern countries of Mexico, such as Guatemala, Honduras, Nicaragua, and Costa Rica.
