What gas makes up a majority of Earth'satmosphere? oxygen O2 argon Ar nitrogen N2 carbon dioxide CO2 at warm temperatures molecules grow in size at warm temperatures molecules slow down at warm temperatures molecules move around more (more kinetic energy) at warm temperatures molecues stop moviing How do molecules at warm temperatures differ from molecules at cool temperatures? What might happen if Earth didn't have an atmosphere? everything would go flying off into space We wouldn't be able to breathe The seasons would be longer The Earth's rotation would stop What happens when you put a piece of wood into a campfire? chemical energy in the wood is released electrical energy in the wood is released energy is released due to friction solar energy is released Place the following atmospheric layers in the correct sequence from lowestto highest A)exosphere B) stratosphere C)troposphere C, A, B C, B, A B, C, A A, B, C Why is it difficult to breathe at high altitudes? because there is more carbon dioxide the higher you go because there is no oxygen in the troposphere because atmospheric gasses become thinner the higher you go (less molecules of gas) because you are closer to the sun the higher you go If you wanted to fly through a cloud, which atmospheric layer would you fly through? exosphere stratosphere mesophere trophosphere stay all around the radiator spread out evenly throughout the room stay near the floor move all to thesolar collector In this picture, the home is beingheated by a solarheating system.The heated air that comes from theradiator will..... The type of heat transfer that occurs when the atoms or molecules flow is ________________ convection radiation conduction sun's rays As molten lava flows into the ocean, it quicklycools and hardens. Which of the following bestdescribes why this occurs? The ocean water is more dense than the lava Thermal energy in the lava transfers to the cooler ocean water Thermal energy in the ocean water is transferred into the lava The salt in the ocean water reacts with the lava Which best represents the direction that heat will move when the test tubes are placed in the water bath? heat will move from the 20 into the 50 and 10 heat will move from the 10 to the 20 and 50 heat will move from the 50 toward the 20 and 10 A teacher puts one testtube of 50 degree liquidand one test tube of 10 degree liquid into a 20degree water bath as shown. The compound Ammonia is found in trace amountsin our atmosphere. Its chemical formula isNH3.Which elements make up Ammonia? Nitrous oxide Hydroxide and Neon Nitrogen and Hydrogen Sodium and Helium radiation conduction convection solar The diagram shows a bunsenburner heating a beakerof water on a stand.How is the heat being transferred to the beakerof water? conduction radiation convection biomass Molten magma rises in Earth's mantle and then sinks back toward the core in a circular pattern as shown in this diagram. This method of heat transfer is known as: a b c d Formaldehyde is found in trace quantities in our atmosphere. Its chemical formula is CH2O. How many elements are present in this compound? 4 0 1 3 |
