The TFR is a total fertility rate that is actually a number of children born to women. Having an age-specific birth rate remaining constant through ages.
The TFR for the world as per the UN is about 2.1 per woman and is called as replacement rate. The TFR during 1950 was 4.96 which dropped to 2.47 in 2020. Higher the fertility more will be population density. Thus indicating a huge population growth. Hence the young and developing nations have a high population growth rate.Hence the correct option is B.

effect of reduced summer cloud shading on evaporative demand and wildfire in coastal southern california.
The effect of reduced summer cloud shading on evaporative demand and wildfire in coastal southern california have enhanced daytime solar radiation and evaporative demand throughout much of CSCA, particularly in greater Los Angeles and northern San Diego.
Cloud shading limits surface radiation, thus reducing vegetation water stress and, presumably, flammabilitySince the early 1970s, cloud observations from airfields in coastal Southern California (CSCA) indicate reductions of ~25–50% in warm-season frequency of daytime stratus clouds at many sites, including fire-prone wildland-urban interface zones.they use 10 years of meteorological, surface radiation, and cloud observations to statistically model the effects of clouds on warm-season surface energy fluxes in CSCA.Forcing our model with cloud observations, we estimate that reduced warm-season cloud shading since the 1970s significantly enhanced daytime solar radiation and evaporative demand throughout much of CSCA, particularly in greater Los Angeles and northern San Diegoto know more about water stress click here

what of the following displays the correct order earth’s layers from the planet’s surface to its interior?
Answer:
Explanation:
What is the correct order of the Earth's layers from the interior to the surface?
Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust.
The right order of Earth's layers from the planet's surface to its inside is Crust, mantle, Outer Core, and Inner Core.
Crust: The furthest layer of the Earth, going in thickness from around 5 to 70 kilometers. It is made out of strong stone and is separated into mainland hull (underneath bodies of land) and maritime covering (underneath the sea floor).
Mantle: Underneath the hull is the mantle, stretching out to a profundity of around 2,900 kilometers. The mantle is made out of semi-strong stone that streams gradually over land timescales.
Outer Core: Underneath the mantle is the inner layer, stretching out to a profundity of around 3,000 to 5,000 kilometers. The inner layer is made out of fluid iron and nickel and is liable for producing Earth's attractive field.
Inner Core: At the focal point of the Earth lies the internal center, reaching out to a profundity of around 5,000 to 6,400 kilometers. The inward center is made out of strong iron and nickel because of the gigantic strain, regardless of the great temperature.

What would you call a thunderstorm with baseball-sized hail and straight-line wind gusts to 80 mph?.
A derecho is a type of thunderstorm with hail the size of a baseball and wind gusts up to 80 mph in a straight line.
A derecho is a wide-spread, prolonged, straight-line windstorm that is associated with a mesoscale convective system, which is a fast moving collection of hazardous thunderstorms.
Derecho, which means "straight" in Spanish, refers to a direction. Parts of southwest Missouri were battered by the same thunderstorm complex with baseball-sized hail.
An arced, curved line of thunderstorms known as a derecho produces strong winds as it fans outward. It is not uncommon for the wind speeds in a derecho to reach up to 90 mph, rivaling those of a weak tornado.

Supercell thunderstorms are defined as thunderstorms with hail up to the size of a baseball and straight-line wind gusts of up to 80 mph.
Although supercells are the least frequent form of thunderstorm, they are highly likely to generate severe weather, including strong winds, very big hail, and occasionally mild to destructive tornadoes.
The presence of a mesocyclone, a deep and enduring revolving updraft, distinguishes supercell thunderstorms from all other forms of thunderstorms. Supercell thunderstorms can linger for several hours if the conditions are favorable.
Supercells may be classified into a number of different categories, such as classic, heavy precipitation, low precipitation, and even miniature.
Although supercells need some buoyancy, the most important element is moderate to severe speed and directional wind shear between the surface and around 20,000 feet.
In addition to causing the mesocyclone, wind shear also makes it possible for the storm to be tilted, which is crucial for maintaining a distinct updraft and downdraft zone. Because there is less chance that too much rain-cooled, stable air from the downdraft area will be swallowed into the updraft, causing the storm to diminish, a distinct updraft and downdraft permits the supercell to last longer.

The sun is so massive that it creates gravity.
The sun is releasing heat and pushing objects away.
The sun is moving so quickly that other objects move around it.
Answer: The sun is so massive that it creates gravity
Explanation: i just took this assessment on Conexus.
A video shows the objects in the solar system orbiting the sun. The objects orbit the sun because The sun is so massive that it creates gravity. Thus the correct option is B.
What is Sun?A Sun refers to a star present in the solar system due to having its own light. All the planets present in the solar system orbit around the sun. Earth is the only plant in the solar system on which life exists.
The sun is referred to as a source of energy used in teh process of photosynthesis with the help of which plants prepare their food as they consume carbon dioxide and release oxygen which is essential for breathing.

Explanation:
What would you call a thunderstorm with baseball-sized hail and straight-line wind gusts to 80 mph?.
Supercell thunderstorms are thunderstorms with straight-line wind gusts of up to 80 mph and hail up to the size of a baseball.
Supercell thunderstorms, which are extremely massive and continue for hours, produce tremendous volumes of rain and occasionally even baseball-sized hail. They have deep, spinning updraft winds.
They include fast-moving convection, which causes air to shoot upward at speeds of up to 280 kilometers (175 miles) per hour. Due to the storms' prolonged duration, rotation in supercells can occasionally produce the strongest and most destructive tornadoes. One supercell thunderstorm has the potential to spawn many tornadoes. The height of supercell clouds in the atmosphere can reach 18 km (11 miles), all the way to the stratosphere's base. Although supercell thunderstorms are the least frequent, they are the most dangerous.
