| Question | Answer |
|---|---|
| The modern atmosphere contained oxygen that was probably produced by___ in the process of_____. these phytoplankton were thought to have produced the first oxygen in our atmosphere | cyanobacteria in the process of photosynthesis |
| The % of carbon dioxide in the atmoshpere is___which why a small increase can have a large affect | 0.01-0.1% |
| compared to the size of the earth, the atmosphere is a ______ _____ | thin shell |
| the five layers of the atmosphere are... | Exosphere, Thermosphere, Mesosphere, Stratosphere, Troposhere |
| most of our weather takes place in____ and is ozone is harmful because_____ | the troposhere, defective for humans and life |
| the ozone layer is located in the _____ because ____ | stratosphere "upper atmosphere", it absorbs harmful UV rays |
| most of our air (99%) is located in what two layers | stratosphere, troposhere |
| temperatures in the thermosphere can go up to... | 2000 degrees Celsius! |
| the_____is where radio waves can be reflected around the world | thermosphere |
| what are the tree types of heat transfer | convection, conduction, radiation |
| seasons on earth are caused by the ____ of ____degrees of the planet | tilt of 23.5 degrees |
| what accounts for our changing weather | The atmosphere's continual struggle for temperature balance (air temperature) AIR PRESSURE?? |
| what causes air pressure? | caused by the weight of the air pressing down on the Earth, the ocean and on the air below |
| list some types of precipitation | rain, snow, sleet, hail air containing water vapor cools in atmosphere and therefore condenses to form droplets of liquid water |
| what causes winds to spiral on the surface of the Earth? | falling of high to low pressures (Coriolis effect) CAUSED BY PRESSURES VS. SPEED? |
| what is the rain shadow effect? | Prevailing winds pick up moisture from an ocean. On the windward side of a mountain range, air rises, cools, and releases moisture. On the leeward side of the mountain range, air descends, warms, and releases little moisture. THIS MAKES |
| organisms living in an ____ zone are limited to access by light, nutrient availability, and amount of dissolved oxygen in the water | aquatic |
| the two most important factors that determine the climate of an area are_____ and ______ | precipitation and temperature |
| climate is the most important factor that determines where a ____ is found | biome |
| the coral reef is to water environments as the _________ ______ is to land environments with regards to biodiversity | tropical rain forest |
| what's a lake overturn in a freshwater lake? | layers in fall and spring (stratification) MIX the benthic (bottom layer) goes to the top layer |
| estuaries exhibit _______ and _______ because of tides flowing in and out and the hot sun rising and setting | salinity and temperature |
| the desert biome is what? | -has succulent plants (like catci) that hold lots of water in spongy tissue - some living organisms "barely cling to life as it is" -dry and inhospitable - threats: off roading, mining, overgrazing |
| greenhouse gases | water vapor (h2o) carbon dioxide (co2) methane (CH4) hydrofluorocarbons (SF6-sulfur hexafluoride) (HFC) perfluorocarbons (PFC) nitrous oxide (n2o) |
| air at the lower latitudes near the _____ tends to heat up and rise. it's at zero latitude | equator |
| the grassland biome is what? | has prairie dogs, insects, coyotos, hawks, foxes - fire is danger threats: fire, farming, development |
| the abyssal zone is what? | -deepest zone in the ocean -has hydrothermal vents at the bottom of the ocean -organisms here get their oxygen from chemosynthesis that come from chemical compounds NOT the sun |
| ecosystems with the highest NET PRIMARY PRODUCTIIVTY per unit area are found in the ____ zone of the ocean | coastal |
