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.

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.

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.

Clouds
Our 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.
Click on the link below, and watch The Types of Clouds clip.

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

Cumulus

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.
