Effect of Space and Earths Atmosphere on Organisms
| Question | Answer |
|---|---|
| Such factors as Earth's atmosphere , the ozone layer, the presence of oxygen and water, light from the sun and the force of gravity. | Factors That Allow Life On Earth |
| Closest to the Earth, this layer of the atmosphere is where weather and the water cycle occur, more that 1/2 of the air in the atmosphere exist here (densest layer), only layer we can breath in! | Troposphere |
| Second layers from Earth's surface, this is where jets fly, it contains the jet stream at the base and ozone layer at the top. | Stratosphere |
| The middle layer is the coldest layer of the atmosphere, meteors burn up here due to collision with certain gases. | Mesosphere |
| The fourth layer from Earth's surface, this is the hottest of all layers, auroras occur here. | Thermosphere |
| The outermost layer of the Earth's atmosphere, some satellites orbit here. | Exosphere |
| Air is a mixture of gases and has mass. It is composed of: 78% nitrogen, 21% oxygen, and the last 1% is a mix of other things such as CO2(Carbon Dioxide), Noble gasses and water vapor. | Air Composition |
| Wind from convection currents because warm air rises and cool air, which is denser, descends- This creates a cycle of air motion that create(s) currents. | Wind |
| Bad ozone- Which exists at the top of the Troposphere, is a by-product of burning fossil fuels and a pollutant. Good ozone- Exists at the top of the Stratosphere and absorbs harmful UV Rays and the high temperatures that would accompany them. | Ozone |
| A force must be applied greater than the force of gravity to lift-off in order to get out of out atmosphere. | Launching Into Space |
| Some of the basics include: oxygen, a space suit, water, food, and a space vehicle. | Accommodations For Space Exploration |
