Weather

Introduction

• We are going to take a journey around the troposphere and learn about the weather. We will be going through the water cycle, clouds, and storms.

Troposhere

• On our first stop we are going to learn about the troposphere. You will be able to view streamline videos and brain pop videos. You will also follow links to deepen your discovery of the troposphere layer. Be sure to follow all directions given to you.

Troposphere

• The layer of the atmosphere nearest the earth’s surface. This is where all the weather on earth occurs. It is also where we live. It is the lowest layer in the atmosphere. It contains 85% of the earth’s air.http://www.brainpop.com/science/earthsystem/earthsatmosphere/

Water Cycle

• About 70% if the earth’s surface is covered by water. Earth is referred to as the water planet. Not all of the earth’s water is in the oceans.

Process of the Water Cycle

• Evaporation• Condensation• Precipitation• Saturation• Surface Run-off

Evaporation

• Evaporation is the process by which a liquid changes into a gas.

Condensation

• Condensation: is the process by which a gas, such as water vapor, changes into a liquid. Condensation occurs when moist air cools.

Precipitation

• Precipitation: Any type of liquid or solid water that falls to the Earth’s surface.

Surface Run-off

Water runs off into bodies of water, or soaks into the ground as groundwater.

CloudsOur third stop is going to be clouds.We are going to learn how clouds are formed, the types and what kind of weather they bring. We will using various websites, streamline videos, and brain pop.

How Clouds are Formed

• Clouds are made of condensed water vapor. As warm air rises in the atmosphere, it cools. When the air cools to its dew point, the temperature

Types of Clouds

• Cumulus• Cirrus• Stratus• Cumulonimbus• Nimbostratus

Clouds• Cumulus-Puffy clouds that look like cotton balls• Cirrus- Thin wispy clouds that bring fair

weather.• Stratus-low, layered clouds that cover the sky.

Fog is an example.• Nimbostratus-layered clouds that contain rain.• Cumulonimbus- Large towering clouds that

usually contain thunder, lightning, and rain.

Thunderstorms

• A thunderstorm is a storm with lightning and thunder. They get their energy from humid air. When warm, humid air near the ground moves up vertically into cooler air above, the rising air, or updraft, can build a thunderstorm quickly.
