Why study for a quiz/test? • How to study: • Review your Notes (read them over carefully) • Read over sections in the textbook or review book you are not clear about • Practice sample questions: from the review book/practice quiz or online (regentsprep.org) • Memorization – flash cards, copy lists
Key Concepts for Quiz • Convection – process of heat rising due to density changes (candle and smoke!) • Conduction – Transfer of energy molecule to molecule (has to touch) • Insolation – the energy (radiation) received from the Sun (through space) • Various forms of radiation distinguished by wavelength
Key Concepts for Quiz Continued • Reflect – radiation reflected back out of the Earth’s atmosphere • Absorb – take in radiation (opposite of reflect) • Scattered – radiation which is spread around in the atmosphere
Quiz Review • When the Earth receives radiation from the Sun, not all of it is absorbed. • Some of the energy is reflectedand/or scattered.
Quiz Review • The energy that is absorbed by Earth is absorbed by various surfaces. • Darker colored surfaces reflect less light but absorb more energy. • Lighter colored surfaces reflect more light but absorb less energy.
Quiz Review • The gasses that contribute to the Greenhouse Effect are • Carbon Dioxide (CO2) • Methane (CH4) • Nitrous Oxide (N2O) • Water Vapor (H2O) • These contribute to the climate change!
Quiz Review • In page 14 of the ESRT there is a chart of the atmosphere and the different parts of it. • We discussed that the ozone (O3) layer is in the stratosphere. • What is noticeable about the different parts of the atmosphere? • Temperature Zones • The “pauses” between them. • Altitude
Quiz Review • Radiation is on ESRT page 14. • Notice two things: • Wavelength of radiation increases from right to left.
Question #1 • Answer is #1 • Think of a blacktop in the summer. It gets hot quicker because it is a dark surface that absorbs energy and reflects less!
Question #2 • Answer is #2 • LOOK AT THE SPIKE ON GRAPH – NO OTHER INFORMATION IS NEEDED TO GET ANSWER.
Question #3 • Answer is #1 • Look at picture on ESRT (page 14) and it gives answer! • There is no temperature given off, different source, or differing speeds. • Process of elimination!
Question #6 • Answer is #1 • Strictly a vocabulary question. • Terrestrial radiation is infrared. • Specific heat – how easily things heat up. • Convection – process of moving heat due to density differences.
ESRT P.1!! • There are two main gasses within the atmosphere: • Nitrogen (78%) • Oxygen (21%) • 98% of the atmosphere are made of these gasses! • We need these to survive and maintain life on Earth.
Question #8 • Answer is #3 • Kilometers are on the left hand side, miles are on right hand side.
