ATMOSPHERE AND WEATHER ATMOSPHERE • The atmosphere is a blanket of _______________ that covers a planet. • Atmospheres tend to get ___________ dense as you travel away from the planet. • The air molecules get __________________ apart. • There are _______main levels of Earth’s atmosphere. • a.) The closest layer to earth is called the _________________________. • b.) The second layer is called the ______________________________. • c.) The third layer is called the _______________________________. • d.) The last layer is called the _______________________________. • 1. This layer also has two layers within it. There are called the ____________________ (which is closer to earth) and the ____________________ (which is the farthest part of the atmosphere). • Layers of the atmosphere start at different altitudes. • The troposphere starts at _________km and extends to around _________km. • The stratosphere starts at ________km and extends to ________km. • The mesosphere starts at _______km and extends to ________km • The thermosphere starts at _______km and has no ______________. • The layers are divided based on their ________________________. • The temperature in the troposphere and the mesosphere ______________________ as you move farther from earth. • The temperature in the stratosphere and the thermosphere ______________________ as you move away from earth. • Each layer is unique and has different events or serves different functions. • In the troposphere you would expect to find ___________________. This is the densest layer of the atmosphere. • In the stratosphere you would find the _________________ which protects us from the sun, or see ______________ flying. CONTINUED… • In the mesosphere you would be able to see _________________ burning up since this layer protects us from collisions. This is the coldest layer of the atmosphere. • In the thermosphere you would expect to see the ________________ ________________ or a ___________________ orbiting. This is the hottest layer of the atmosphere. ENERGY IN THE ATMOSPHERE • The energy from the sun travels in waves. Different types of energy have _____________________________ wave lengths. • Most energy from the sun reaches the earth in three different forms: • _______________________radiation which come to the earth as heat ( _______________waves). • ______________________radiation which is harmful and can give you sunburn (____________________ waves). • __________________ __________________ which we can see as colors ( _____________________ waves). • Some of this energy is _____________________, while the rest is reflected off snow, clouds, water and other surfaces. • The _________________________helps hold much of this energy close to the earth. When heat is held close to the earth in this way it is known as the ________________________ _________________________. CLIMATE CHANGE • Climates change very ___________________, but can have ______________ effects on living things in an area. • Scientists study climate change through ____________________, ________________ _____________________, and _____________________. • Earth’s climate has changed several times in its history. Earth goes through warm periods as well as ________________ periods know as ___________ _______________. • There are _________________ and _________________ causes of climate change. • Natural causes include: the distance between earth and the _____________ as well as the ___________ or tilt of the earth. Also changes in the amount of _______________ the sun gives off and movement of the __________________. These are slow changes that can cause major changes in climate. • Human factors include: the adding of _________________ from burning coal and oil to the atmosphere. These gasses hold extra _______________. • Effects of Global warming • Positive effects include warmer climates for farmers to grow extra ______________. • Negative effects include a rise in ocean temperatures which could cause a greater number of powerful ________________. This could also cause melting of the __________________ which would _______________ the sea level. Finally climates changes could kill many organisms that cannot _____________ fast enough to the changing environment and may cause them to go ______________________.
