What are 3 major variables that affect our weather? WATCH THE VIDEO! Factors that affect Temperature What is moisture? Water found in one of its three forms: 1. SOLID (ICE/SNOW) 2. LIQUID (RAIN) 3. GAS (WATER VAPOR) Precipitation is moisture that FALLS from the atmosphere above. Precipitation cleans the atmosphere of condensation nuclei Why does precipitation occur? Air can only hold a certain amount of water vapor before it will overfill and condense This is known as capacity ROOM FOR ONE MORE???? What temp. air can hold more W.V.? Warm air can hold MORE water vapor WHY????? Cold air holds LESS water vapor Every 10 degree Celsius increase doubles the air?s capacity Every 10 degree Celsius decrease cuts capacity in half * * * * * * * * * * * * *

Air Pressure The weight of the air above Earth?s surface Thanks to gravity, the atmosphere has weight. What affects air pressure? Altitude ? air pressure decreases the higher you go up 2 miles up Sea level Decreasing Air Pressure Higher Concentration of air molecules Gravity forces most air molecules to remain close to Earth?s surface Cold air is more dense than warm air Cold air has higher air pressure because the molecules are closer together v v COLD HOT Warm air has LESS air pressure because molecules are farther apart COLD HOT Which air mass can hold more water vapor? v v COLD HOT v v c COLD HOT Air Molecule Water Molecule Warmer air can hold more water molecules than cooler air

Campbell's Biology, 9e (Reece et al.) Chapter 3 Water and Life Life evolved in the ocean, and the chemistry of life occurs in an aqueous environment. These questions explore the properties of water that are important to sustain life?s chemical processes, organismal physiology, and interactions of organisms with their environment. Quantitative properties such as heat content, molarity, and pH are also addressed. A few questions address how human activities affect the global environment through acid rain and acidification of the ocean. Multiple-Choice Questions 1) In a single molecule of water, two hydrogen atoms are bonded to a single oxygen atom by A) hydrogen bonds. B) nonpolar covalent bonds. C) polar covalent bonds. D) ionic bonds. E) van der Waals interactions.

Chapter 6 The Chemistry of Life Atoms and Their Interactions Elements Carbon, hydrogen, oxygen, and nitrogen make up more than 96% of the mass of a human body. Atoms All nuclei contain: positively charged particles called protons (p+) particles with no charge called neutrons (n0). Electron cloud The region of space surrounding the nucleus contains extremely small, negatively charged particles called electrons (e-) This region of space is referred to as an electron cloud. Energy levels The first energy level can hold only two electrons. The second level can hold a maximum of eight electrons. The third level can hold up to 18 electrons. How many electrons are in fluorine?s 2nd energy level? How many protons are in an atom of fluorine? Isotopes

Name Period Chapter 3: Water and Life Concept 3.1 Polar covalent bonds in water result in hydrogen bonding Study the water molecules at the right. On the central molecule, label oxygen (O) and hydrogen (H). What is a polar molecule? Why is water considered polar? Now, add + and - signs to indicate the charged regions of each molecule. Then, indicate the hydrogen bonds. Explain hydrogen bonding. How many hydrogen bonds can a single water molecule form? Concept 3.2 Four emergent properties of water contribute to Earth?s suitability for life Hydrogen bonding accounts for the unique properties of water. Let?s look at several. Cohesion, Adhesion, and Surface Tension Distinguish between cohesion and adhesion.
