'Distance From the sea and prevailing winds determine the climate of a place'. Justify with examples​

Answers

The bigger the distance from the equator the lesser the angle at which the sunlight falls on the surface of the Earth. The smaller the angle of the sunlight the lesser the heating because of the greater dispersal of the sun rays which cause cooler temperature.

Oceans are significantly slower to heat up and chill down than land. This means that, at the same latitude and altitude, coastal sites are colder in the summer and warmer in the winter. Glasgow, for example, is at a comparable latitude to Moscow, but its winters are much milder due to its proximity to the shore.

Krill feed on the algae that grow at the base of sea ice. Less sea ice means less food for the krill, which means fewer krill. In 2004, the British Antarctic Survey noted a striking decline in krill numbers in Antarctica. reduction in sea ice is hammering local penguin populations; at the Palmer Research Station, the number of Adélie penguins has dropped some 65% since 1990. Adélies need that sea ice, and feed almost exclusively on the declining krill

If mars had life and resources and there were people what would happen?

Answers

Answer:

if they were

Explanation:fter mapping cosmic radiation levels at various depths on Mars, researchers have concluded that over time, any life within the first several meters of the planet's surface would be killed by lethal doses of cosmic radiation.

Answer:

knowing humans and how greedy they are, mars would probably become a hot spot for the upper class. after they make sure it is safe, people would probably charge thousands of dollars to go there. ooooorrrr it would be the complete opposite and they would send the lower class they for "free" and use them as an experiment to see if its safe for everyone else.

it would probably just be an earth 2, except there are not much resources there that we can take.

This is just my cynical POV.
