| − | + | In New Zealand the elevation is mostly a little above sea level, despite a few mountain tops. This elevation causes the temperature to stay at a hot temperature. Another factor of New Zealand's climate is that New Zealand lies north of 60˚ latitude, where it’s easy for the sun’s rays to reach Earth. This makes the climate of New Zealand warmer. Because New Zealand is in a low pressure zone and winds spiral out of highs and into lows, it affects the temperature a lot. Low pressure zones means that the climate is humid and warm. Because New Zealand is surrounded by water, the island has many sea breezes from all directions. These sea breezes circulate cool air into the climate. The topography of New Zealand causes there to be very diverse climates throughout the region. Some areas are barley above sea level, while others are above 12,000 feet on the peeks of mountains. This means that temperatures can vary a lot. In a valley the climate could be almost 80 degrees and just a mile east could be a mountain with snow at its peak.

Factors that Affect Antarctica’s Climate
Antarctica is generally mountainous with elevations ranging from 6,600 Ft. to 13.200 Ft.. Because temperature decreases with altitude, Antarctica’s elevation is a factor of why it’s so cold. Another factor of Antarctica’s climate is that Antarctica lies south of 60˚ latitude, where it’s difficult for the sun’s rays to reach Earth. Plants (or absence of) are another factor of Antarctica’s climate. This is because Antarctica is a desert (due to Antarctica containing cold, dry air) and the definition of desert is any barren land with very little rainfall, extreme temperatures (hot or cold), and sparse vegetation, so even vegetation (or lack thereof)can help determine Antarctica’s climate. Even the waters surrounding Antarctica play a role in determining Antarctica’s temperatures and precipitation. The Southern Ocean, an ocean bordering Antarctica, is home to the Antarctic Circumpolar Current, the most powerful current on Earth, which flows east completely around the Earth in a great circle just to the north of Antarctica. This current tends to bring cold water to the south, near Antarctica, and warmer water to the north. Also, because water cools slowly and heats slowly, it will keep cool because Antarctica is generally freezing and the Antarctic Circumpolar Current brings cold water to the already cold water. The cold water will also affect the climate of Antarctica because one, the water is surrounding Antarctica, which is basically a island made out of ice, and two, because of sea breezes and land breezes etc. [16] However, ocean currents that keep the waters cold don’t just show up by themselves; prevailing west winds “drag” ocean currents, primarily westerlies, along beneath them. And why do the winds head toward Antarctica? Because Antarctica is in a low pressure zone and winds spiral out of highs and into lows. Low pressure also means that Antarctica is very cold and dry, and that affects the climate a great deal. [17]
