| Question | Answer |
|---|---|
| what are the two factors used to identify climate? | temperature and precipitation |
| How does latitude affect the temperature of a region? | The closer you are to the Equator, the more direct rays of sunlight you receive. More intense sunlight leads to higher temperatures. |
| What global wind belt do we live in? | prevailing westerlies |
| In which ocean does El Nino occur? is it warm or cold shift in the current? | pacific ocean, warm |
| What is a monsoon? where do they occur? | A monsoon is a seasonal wind that often brings heavy rainfall to parts of Asia, Africa, and Australia. |
| what climate zone and sub climate do we live in? | We live in the mid-latitude (temperate) climate zone, and the humid continental sub-climate. |
| how do volcanic eruptions affect climate? | they eject ash and sulfur dioxide into our atmosphere. This partially blocks out sunlight, which causes cooling in the atmosphere. |
| what percentage of the worlds population lives on the near coastlines? | 40% |
| which green house gas are climatologist worried about the most? | Carbon dioxide |
| what action can you take to reduce your impact on climate change? | consume less energy and and water - shut off light when out of a room and fix leaky facets |
| how are proxies used to study past climates? | scientists can examine fossils about when rocks were deposited they use this information to reconstruct the climate story for that location |
| what is the urban heat island effect, and what causes it? | as the population center grows it tends t expand its areas and increase it's average temp and it causes modification of land surface. |
| what are three components of Milankovitch Theory, and how do they affect climate? | eccentricity, axis tilt, and precision. They combine to affect the amount of solar heat that's incident on the earths surface and subsequently influence climate patterns |
| what is the climate like in the desert? what is it like in the tropical rain forest? | in the desert it is hot and dry with less that 250 mm of rainfall a year. the rain forests average temp is 70-85 degrees its pretty wet with humidity of 77-88% a year, yearly rainfall 80-400 inches a year |
| how does living near a large body of water affect a city's temperature precipitation? | a large body of water has a higher heat capacity than land meaning it takes more energy to warm and cool temperatures of water cities close to water tend to have a narrow range of temperatures throughout the year |
