HYDROSPHERE
• Water is found, within rocks below the surface, as
ice on the surface, and in the atmosphere as water
vapor.
• Water travels between different areas of the Earth
through the water cycle.
• About 70% of the Earth surface is covered with
water, and most of that is the ocean.
FRESH WATER
• Only a small portion of the Earth's water is
freshwater, which is found in rivers, lakes ,ice and
groundwater
FRESH WATER USES
• Freshwater is needed for drinking, farming, and
washing. In addition to liquid water, water is also
present on Earth in the form of ice. Without water,
life as we know it would not exist.
OCEAN CHEMISTRY
• Why is the ocean salty? When it rains on land, some
of the water dissolves minerals in rocks. That water
flows in rivers to the sea. It carries the minerals with
it. When water evaporates back out of the ocean, it
leaves the minerals behind. The minerals make sea
salty water.

WEATHER
Weather is the state of the atmosphere at a given
time and place. Most weather takes place in the
troposphere, the lowest layer of the atmosphere.
WATER MAKES:
Clouds
• Clouds can come in all sizes and shapes, and can
form near the ground or high in the atmosphere.
Clouds are groups of tiny water droplets or ice
crystals in the sky and are formed by different
processes. They can make different kinds of
precipitation depending on the atmosphere's
temperature.
CLOUD TYPES
• At any given time, clouds cover about 50% of the
Earth. We would not have rain, thunderstorms,
rainbows, or snow without clouds. Clouds make up
some of the atmospheric optics we can see in the
sky.

CLIMATE
• Water vapor is part of the water cycle and is also a
Greenhouse gas .
• Water in the ocean traps (stores) heat.
ICE
No matter where you live, the snow and ice of the
Earth’s cryosphere has an impact on your climate.
Recent changes in the cryosphere have had a major
impact on global climate.
ICEBERG
• Ice is stored in large ice caps in Antarctica and
Greenland.
• Glaciers also make up 10% of the Earth’s surface
• Glaciers can be called rivers of ice because gravity
causes them to flow slowly in a downward manner.
• Some glaciers flow to the ocean and break off to
form icebergs.
WATER AND WEATHER
ACTIVITY
Students will create a diagram that shows the
relationship of the water cycle and weather. The
diagram requirements:
• Picture of the water cycling through the atmosphere
showing weather.
• The picture will be labeled with the vocabulary.
• Vocabulary will have explanations of what is happening.
• Arrows will show and explain the traveling of the water
through the atmosphere creating weather.
• Use color to more clearly show what is happening in the
diagram.
