What type of climate would a tundra have?
Tundra regions typically get less than 25 centimeters (10 inches) of precipitation annually, which means these areas are also considered deserts. They have long, cold winters with high winds and average temperatures below freezing for six to ten months of the year.
Why do regions have different climates during the same seasons?
The different kinds of weather you might experience in these regions are caused by moving patterns in the Earth’s atmospheric and oceanic circulation, unequal heating of the Earth, and the rotation of the Earth on its tilted axis.
How does it differ from the climate along much of the coast?
Coastal and Inland Climates
Places at the same latitude may have very different climates if one is on a coast and one is inland. On the coast, the climate is influenced by warm moist air from the ocean. A coastal climate is usually mild. Summers aren’t too hot, and winters aren’t too cold.
How is climate change affecting South America?
Latin America’s climate is changing. Precipitation patterns are shifting, temperatures are rising, and some areas are experiencing changes in the frequency and severity of weather extremes such as heavy rains. The impacts range from melting Andean glaciers to devastating floods and droughts.
Does South America have different seasons?

Why is South America so cold?
The cold snap is due to an intense area of high pressure which is positioned over central Argentina. Although areas of high pressure usually bring warm sunny days in the summer, in winter, when the sun isn’t as strong, a succession of clear nights allows heat to escape and soil temperatures to drop.
Which coast of South America has a more moderate climate?
