Gravity Air resistance
Solute Effect Pure Water: High Vapor pressure Small rain drop Salty Water: Low Vapor pressure Large rain drop

Bergeron Process (ice-crystal process) Ice grows at the expense of water drops.
Accretion (riming) Ice collecting suppercooled water drops Results in icy snow pellets called graupel
Aggregation Ice collecting small ice particles to make a snow flake
Fall Streaks -- icy crystals or snow falling
Dendrite snow crystal

1 Understanding Weather Weather results from differences in pressure, heat, air movement, and humidity.
THE WATER CYCLE The water cycle the continuous exchange of water between Earth's surface and atmosphere is Earth's natural mechanism for recycling water.
1.Why is the moist adiabatic lapse rate lower than the dry- adiabatic lapse rate? Heat is released during condensation. 2.When temperatures are below freezing,
What is Weather?. Weather… refers to the state of the atmosphere at a specific time and place. refers to the state of the atmosphere at a specific time.

QPA Review for 3 rd 9 Weeks. Ch.10 Fresh Water 1. What percent of Earth’s water is salty? What percent is fresh?
HOW DO CLOUDS FORM AND PRECIPITATION TYPES (DO NOT WRITE WHAT IS IN BLUE) RRB
Have you ever just looked at clouds? Why do we have clouds? Why do we have clouds? Why are there different shapes? Why are there different shapes? What.
Water in the Atmosphere. H 2 O exists in atmosphere in all three states of matter…
Weather Part 3 The Clouds. Clouds form when the air temperature cools and causes water vapor in the air to condense into tiny drops of water.
WHAT IS WEATHER? Chapter I. Factors of Weather A. Climate or Weather? A. Climate or Weather? 1. Climate is…. the pattern of weather over an area.
Weather and Climate Chapter 2 February, Bell Work What is condensation? What is dew point? Can you find dew in the air?
Snow, Sleet, Freezing Rain. To make snow, the temperature must be below freezing the entire path until at the surface. Once snow melts as it is falling,

Clouds March 11, Clouds 1. _Clouds- are a collection of millions of tiny water droplets or ice crystals.
Chapter 15 Water. Water Molecules l O is more electronegative than H l Gives O a partial negative charge l Bent shape makes molecule polar l Strong hydrogen.
Review 13: Weather. 1.Meteorologist – scientists who study the weather. What direction do most weather systems travel in the U.S.? Review 13: Weather.
Water Evaporation Heat energy from the sun causes water in puddles, streams, rivers, seas or lakes to change from a liquid to a water vapor. This.
The Water Cycle Water Cycle Evaporation Condensation Precipitation.
WEATHER What will the weather be?. WEATHER n Predicting the weather is a hard thing to do. It is easy to see what the weather is like right now by going.
