It is warmer at the equator than at 80° n because
the equator is closer to the sun
the equator receives more sunlight
the sun's energy is spread out over a smaller area at the equator
the sun's energy is spread out over a larger area at the equator


what causes seasons?
the earth's rotation
the earth's tilt
the curved surface of the earth
the earth's orbit around the sun

which of the following statements is true?
low pressure is usually means nice weather.
air pressure is the same over the entire earth.
worldwide winds are caused by rising air at the poles and sinking air at the equator.

5- Option (a), (b) and (d)

6- Option (d)

Explanation:

The equatorial region receives more sunlight than the polar region, so the places near equator are warmer than the places at the polar region, including the 80 degrees N latitude.

Seasons are caused due to the tiltation of the earth and the relative position of earth with respect to the sun.

Due to the increasing temperature near the earth's surface, the warm air rises up in the atmosphere, being less denser and eventually sinks due to the lowering temperature.

When there occurs the temperature difference between two different regions, then wind is generated blowing from the region of higher pressure to the region of low pressure.

Clouds are formed when condensation process takes place and are a good albedo that reflects significant amount of sunlight back into the space. Clouds during condensation starts precipitating in the form of rainfall, snowfall and fog.

The difference in the temperature occurs because of the unequal heating of the land surface and the ocean. The land area gets heated up faster and more readily, in comparison to the ocean. So the sea breeze as well as the land breeze occurs. Sea breeze blows from the ocean surface to the land area, whereas land breeze blows from the land area towards the oceans.

the answer is b)3/8x+1

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
