Lesson 2
Interactions of Earth
Systems
The Water Cycle
 The continuous movement of water
on, above and below Earth’s
surface.
 Driven by the energy of the Sun.
No beginning and no end.
Water Cycle
Evaporation
The process by which a
liquid, such as water,
changes into a gas.
Evaporation
Transpiration
The process by which
plants release water vapor
through their leaves.
Transpiration
Respiration
 Water and carbon dioxide are
produced during cellular respiration.
 When animals breathe, they release
carbon dioxide and water vapor from
their lungs into the atmosphere.
Condensation
The process by which a
gas changes to a liquid.
Condensation
Precipitation
Moisture that falls from the
clouds to Earth’s surface.
Rain, sleet, snow, and hail.
Precipitation
Water Cycle
Complete the water cycle
worksheet with the teacher.
Weather
The state of the atmosphere
at a certain time and place.
Humidity
The amount of water vapor
(gas) in a given volume of air.
High humidity more likely
clouds and precipitation.
Relative Humidity
Compares the actual vapor
density in the air to the amount
of water vapor the air could
contain at that temperature.
Math Skills
Page 90
Complete the practice problem
with the teacher then complete
the math practice worksheet.
Climate
The average weather pattern
for a region over a LONG
period of time.
Mountains
Air temperature decreases (goes
down) as the altitude increases
(goes up).
Mountains can affect the amount
of precipitation an area receives.
Ocean Currents
As wind blows over the ocean
currents are created on the
surface of the water.
These currents transport
thermal (heat) energy from
place to place.
Rock Cycle
 The series of processes that
transport the continually change
rocks into different forms.
 This is a very SLOW process and
occurs over thousands and millions
of years.
Cooling and Crystallization
Mineral crystals form as
magma cools which changes
the molten material (melted
rock) into igneous rock.
Uplift
The process that moves large
bodies of Earth materials to
higher elevations.
Weathering
Process of beginning broken
down into smaller pieces.
Glaciers, wind, rain as well as
the activities of some
organisms.
Erosion
Occurs when the
sediments are carried by
water, wind, or glaciers to
new locations.
Water
Wind
Glaciers
Deposition
The dropping or settling of
eroded material.
Deposition
Compactions and Cementation
 As more layers of sediment are deposited,
their weight pushes down on underlying
layers.
 Dissolved minerals crystallize between
grains of sediment and cement the
sediments together.
 This is how sedimentary rocks are formed.
High Temperatures and Pressure
Metamorphic rocks forms when
the rocks are subjected to high
temperatures and pressure.
All rock types can become a
new metamorphic rock.
Foldable

Follow the instructions and
complete the pyramid book.
Lesson 2 REVIEW

Complete questions 1-10 on a
separate piece of paper (it will be
collected for a grade).
Restate the question.
