Answer 1

Answer:

Global warming

Explanation:

Weather can be defined as the atmospheric conditions of a particular area over a short period of time.

The elements of weather include precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed.

Climate refers to the change in the atmospheric conditions and manifestation of weather in a particular area over a long period of time usually 30 years.

Pollution can be defined as the physical degradation or contamination of the environment through an emission of harmful, poisonous and toxic chemical substances.

Greenhouse gases can be defined as gases that trap heat within the Earth's atmosphere. Thus, an increase in global temperature is largely caused due to an increase in the amount of greenhouse gases in Earth's atmosphere.

Some examples of greenhouse gases present in the atmosphere are methane, water vapor, carbon dioxide etc.

Global warming can be defined as a gradual increase in the average temperature of Earth's surface, atmosphere and ocean due to artificially induced actions or human activities through pollution such as burning of fossil fuels, CFCs, carbon dioxide, etc.

In this scenario, the range shift provides evidence for the theory of global warming.

B.Larger plants and animals inhabit the area.
C.Biodiversity decreases.
D.Sustainability increases.

Answers

Answer:

I think

Biodiversity decreases does NOT occur as ecological succession progresses. Hence, option C is correct.

What is ecological succession?

The process by which a region's species and habitat mix evolves over time is called ecological succession. These communities gradually replace one another until a "climax community" is attained, such as a mature forest, or until a disruption, such as a fire, happens. A key idea in ecology is ecological succession.

For instance, when a tree falls in an established forest, sunlight may once more be able to penetrate the forest floor, allowing new growth to start. In this instance, fresh, smaller plants would be the first in the succession. Communities are ever-evolving and expanding.

ecological succession is the process by which a biological community's structure changes over time. Primary and secondary succession have been identified as two distinct forms.

Thus, option C is correct.

x = A 21.6 B 12.9 C 9.1

Answers

Hi there! Use the equation below.

[tex] \large{sin57 \degree = \frac{10.8}{x} }[/tex]

The reason why we use this equation because we know that sinA = opposite/hypotenuse. Here we focus on 57°. Our opposite would be 10.8 and hypotenuse is x. Hence sin57° = 10.8/x

You might need a calculator or a trigonometric table to find the value of sin57°. Note that not all values are exact. They are approximate.

Therefore, sin57° ≈ 0.838.

Rewrite the equation.

[tex] \large{0.838 = \frac{10.8}{x} }[/tex]

Solve the equation for x-term.

[tex] \large{0.838(x) = \frac{10.8}{x} (x)} \\ \large{0.838x = 10.8} \\ \large{x = \frac{10.8}{0.838} } \\ \large{x = 12.88}[/tex]

Then round up to the nearest tenth. Hence, the value of x is 12.9

A cone with diameter 10km and a height of 12km

Answers

If you’re trying to find the volume of a cone here is how to do it:


Use the formula: V = pi x r^2 x h/3


I will answer in terms of pi:


So we know that a radius would equal half the diameter. So the radius would be 5. Then square it which would be 25.


V = pi x 25 x h/3


And of course we know the height which is 12. You would plug the 12 in at “h” and divide it by 3 which is 4:


V = pi x 25 x 4


And now we just have to multiply 25 and 4 which is 100.


V = 100pi


In terms of pi, the answer would be 100pi.


If you don’t want it in terms of pi you would multiply 100 times 3.14 since pi is equal to 3.14:

V = 100 x 3.14
= 314



So the answer would be either:

100pi OR 314

Mrs. Tymes is buying mulch for her flower gardens.
Which option gives her the best price per cubic yard of mulch?

Answers

Answer:

The answer is below

Explanation:

The price list is attached.

From the price list, we can get the price per cubic yard of the mulch. This is done by dividing the price of the mulch by the total cubic yard of the mulch.

A) 3 yd³ for $165

Price per cubic yard = $165 / 3 yd³ = $55 per yd³

B) 4 yd³ for $240

Price per cubic yard = $240 / 4 yd³ = $60 per yd³

C) 6 yd³ for $300

Price per cubic yard = $300 / 6 yd³ = $50 per yd³

D) 8 yd³ for $360

Price per cubic yard = $360 / 8 yd³ = $45 per yd³

Why is the Sahara desert so warm?

One of the reasons at the back of this drastic trade is hidden inside the grains of sand masking the desolate tract. Sand receives warm simply fast; so, while the solar is shining bright, it absorbs all of the warmness directed on the floor. The mild substance is likewise great at reflecting the heat into the surrounding air, making it super-hot.

The desert accommodates a whole lot of North Africa, aside from the fertile vicinity on the Mediterranean beach, the Atlas Mountains of the Maghreb, and the Nile Valley in Egypt and Sudan.
