Introduction to the Atmosphere Activities Name: ______________________________ ___Date: _______________Class: _____ HERE’S THE TAKE AWAY! Station 1 – Layers of the atmosphere Earth’s atmosphere is made up of ______________ layers. Troposphere – 12 miles thick, our ______________________ occurs here. Troposphere contains approx. ____________% of earth’s atmospheric gases. Therefore, the troposphere is the most ______________ layer. Station 2 – Composition of the atmosphere Earth’s atmosphere contains 78% ________________ and 21% ______________ Earth’s position in the solar system is _________________ _________________, which is what the Goldilocks Principle refers to. Plants carry out photosynthesis, which gives us an abundance of ______________. Carbon dioxide is a greenhouse gas. Earth’s atmosphere contains a small amount of CO2, which helps to keep the Earth warm – without the CO2, Earth would be _________ _____________ for living organisms to survive. Station 3 – It’s Just a Phase: Solids, Liquids, Gases Earth is the only known planet that contains materials in all 3 _______________ of matter. Solids: Have __________ energy and tightly ________________ particles that only __________________ in place due to strong chemical bonds. Liquids: Have _________ energy than solids, particles are able to ____________ around and over each other due to weaker chemical bonds. Gases: Have ____________ energy, particles are able to move and fill up all available space because there are no chemical bonds between the particles. Station 4 – The Water Cycle The sun’s energy heats up Earth’s water causing the water to _________________________ into the atmosphere. As the water vapor cools, it condenses to form _________________. When the _________________________ of the cloud becomes greater than the atmospheric density, precipitation will fall back to Earth’s surface. Precipitation collects in Earth’s bodies of ___________________; percolates into the ground, and runs off of impermeable _____________________________. Much of Earth’s ________________ is moved around through the Water Cycle. Station 5 – Earth’s Energy Budget 100% of the Sun’s ____________________ travels toward Earth. Approximately 50% of this energy is either absorbed by the ________________________________ or reflected back into space. This energy never reaches Earth’s _________________________________. The other 50% of the sun’s energy is absorbed by _________________________ materials. About 30% of the energy that is absorbed by the Earth’s surface is ____________________________ back into the atmosphere. Carbon Dioxide in the atmosphere _______________________ some of this heat and acts as a blanket that helps ____________________ the Earth warm. Too much Carbon dioxide in the atmosphere can cause ____________________ warming. Station 6 – Radiation Radiation is a type of heat __________________ that involves the movement of electromagnetic radiation from one place to another. During radiation, _______________________ is emitted or spreads out and moves away from the source of the heat. Dark surfaces (land, asphalt) absorb __________________ heat than light surfaces (water, snow, ice) Light surfaces _____________________ more heat. Earth receives the energy from the sun through ___________________________. Station 7 – Convection Convection is a type of heat transfer that involves the ______________________ of liquids or gases (fluids) _________________________ fluids have lower densities and tend to rise when associated with cooler fluids. ________________________ fluids have higher densities and tend to _________ when associated with warmer fluids. Heat is transferred by the _____________________________ of the molecules. Earth’s atmosphere and oceans are heated largely by the process of _____________________________________ Station 8 – Conduction Conduction is a type of heat transfer that involves particles coming into __________________________ with one another. When this contact occurs, heat is __________________________ from one particle to another. Some objects are good at conducting heat – glass and metal. Some objects are not so good at conducting heat and are considered _________________________________ - plastic and wood. Conduction occurs as molecules of _________________ come into contact with Earth’s surface.
