The quote states that we should be using solar energy before our limited amount of naturally occurring oil and coal runs out. Meaning; we should be proactively working towards solar power rather than to wait for our resource to run out to start.

Which process is responsible for the greatest loss
gulaghasi [49]
I think the correct answer from the choices listed above is option 4. I think it is the process of convection that is responsible for the greatest loss of energy  from Earth’s surface into space on a clear night. Convection happens when a mass which contains heat energy is in motion. This happens in wind blowing, oceanic currents and other naturally occurring fluid flows.<span />

If a circle has a radius of 4. then the area of the circle is
saw5 [17]

Answer

16\pi or 50.24 units

Explanation:

\pir^{2} and r is the radius, since we know what the radius is (<em>r </em>) we can put this in to an expression

\pi · 4² = 16 units

If the answer is not 16 then its 50.24 units

Explanation:

Now 16 is the correct answer but just in case I took this a step further.

If we estimate the area by using 3.14 which is ( \pi ) because sometimes that isn't  natural to express the area using \pi

I hope I helped you : )

6. Why does the north-east coast of Canada remain icebound during the winter
kow [346]

The North East coast of Canada remains icebound during winter

because of forcing of the air. As the North East coast of Canada is

located near to Northern poles and is nearer to sea hence the ports of

eastern coast of Canada freezes and the temperature in that area

becomes less than zero degree during the winter time.

Ocean currents are horizontal continuous flow of water from one place

to other . There are two types of ocean currents warm and cold flowing

along the coastline which will have an impact on climate. Thus these

waters are cold and tend to freeze up the ports early in winters.

Refer the given below link for more information on North East Coast
