Unit 3 Test Essay
for parsons unit 3 essay test
| Question | Answer |
|---|---|
| Where is a hurricane formed? | A hurricane is formed in an ocean or large body of water off the coast of Florida. A cyclone is formed in the northwest ocean of Australia. A typhoon is formed north of the equator and west of the international dateline. |
| How is a hurricane formed? | As moisture evaporates it rises until enormous amounts of heated moist air are twisted high into the atmosphere. The winds begin to circle counter clockwise north of the equator or clockwise south of the equator. |
| How can a hurricane cause damage? | Strong winds, storm surge, flooding and tornadoes. |
| How do weather fronts interact with each other? | Air masses interact with each other when 2 different types of air masses collide. If an warm front is denser than the cold front, it collides with it, the warm front takes over the cold front, and vise versa. |
| How do weather fronts affect our weather? | They affect our weather because cold fronts bring clear sunny weather and warm fronts bring stormy warmer weather. |
| How are thunderstorms and lightning are formed? Why don't we get many here in Utah? | Thunderstorms are produced from cumulonimbus clouds. Lightning is formed when the bottom of the cloud is negatively charged and the top is positively charged. Then negative clashes with positive. Utah dont get many because there isn't much water or heat |
| What are local winds and how are they different than global winds? | Local winds are winds that are influenced predominantly by the topographic features of a relatively small region. Global winds are large-scale movement of air by which thermal energy is distributed on earth's surface. |
| What are global winds and how does Coriolis Force have an affect on them? | Global winds are large-scale movement of air by which thermal energy is distributed on earth's surface. Coriolis Force is when clouds or air uniformly rotating frame of reference such as the earth. |
| How do global and local winds affect Utah? | The global winds will keep our basic season temperatures relative, and the local winds will keep our constantly changing weather pattern changing. |
| What is rain shadow and how does it affect Utah? | Rain shadow is region in the lee of mountains that receives less rainfall than the region windward of the mountains. Utah has many mountains, so certain areas of Utah may get less rain from a combination of the mountains and rain shadow. |
| What is energy? | Energy is the capacity of a physical system to do work. Units of energy are joules and ergs. |
| What are some unique qualities of light in the electromagnetic spectrum? | Light is a form of radiation that CAN be seen with our eyes. The electromagnetic spectrum has:Radio waves, microwaves, infrared waves, visible light, ultraviolet, x-rays and gamma rays. These all make up the electromagnetic spectrum. |
| How do temperature inversions form and how do they affect Ogden? | Temperature inversions is when the temperature of air in the atmosphere is cooler the higher up you go. It affects Utah because during the winter when temperature inversions are most common, the Ogden area gets colder. |
| How does the sun's energy affects weather globally and locally? | Suns energy affects globally because it can heat the ocean and land through thermal energy, increasing the global temperatures. Suns energy can affect locally because thermal energy can heat up streets and lakes locally . |
| Why is it important that light can travel as a particle? | it is important for light to travel as a particle because that the only way we can get light since there are no mediums in space. |
| Why does air cool as it rises into the atmosphere? | As the air rises, the pressure on it decreases, there is less air on top of it forcing it down, The air will then spread out, will become less dense, and the molecules of the air will literally expand due to the decrease in pressure. |
| What is convection cooling? | Convection cooling is a decrease in the temperature of an air mass due to the air rising and expanding. |
| What is latent heat? Give and example. | Latent heat is energy stored in molecules. Example- |
