What prevents wind from blowing a straight line from the north pole to the equator

The Coriolis force

Explanation:

The wind generally blows from a region of high pressure to a region of low pressure. This wind when blows in a much larger scale, that is moving from the polar region to the equatorial region, it gets deflected towards the right due to the earth's rotation about ts own axis. This effect is called the Coriolis force.

The Coriolis force is the force that occurs due to the continuous rotation of the earth. Due to this effect, the wind in the northern hemisphere moves in a clockwise pattern, whereas in the southern hemisphere, it moves in an anticlockwise direction.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
