Constructive Forces
Blowing sand forms
dunes.
Soil is
blown from
a field across the road
and fills a ditch.
Stalactites form
in a cave.
A delta is
formed
at the mouth of a
river due to deposition.
Destructive Forces
Plant roots break
apart a
rock.
A rock freezes
and cracks.
A glacier plows
the ground
as it slides down a valley.
Soil gets
washed
away during a flood.
The Sun
The primary source
of light and
heat energy
for the Earth.
The energy source that
powers the water cycle.
a star
The center of our solar
system.
Uneven Heating of the Earth’s Air
This causes wind.
Because this happens,
air currents are
formed.
These currents help
determine the climate of
different areas on Earth.
Warm air rises because
this happens.
Cold air sinks because this
happens.
The Moon
Has no atmosphere.
Its surface is covered
with craters.
Revolves around
the Earth.
Has a 29.5 day cycle.
Rotation of the Earth
Takes 24 hours.
Causes day and night.
The Earth is tilted while Spins on its axis as it
revolves around the sun.
it does this.
Landforms
Mountains, islands,
and glaciers
are some
examples.
Canyons and oceans are
two examples.
Valleys and beaches are
two examples.
Rivers and volcanoes are
two examples.

Non-renewable Resources

Renewable Resources
plants

oxygen and water
soil
Inexhaustible Resources
wind
ocean tides
sunlight
The human population can’t
use these resources up!
Fossils
Usually found in
limestone.
Tell scientists about
past species.
remains of dead
plants and animals
Tell scientists about
past climates.
Water Cycle
evaporation
precipitation
condensation
transpiration
(the water that trees and plants give off
through their leaves)
Rocks
igneous
metamorphic
sedimentary
These are made up of
minerals.
Tides
Caused mainly by the moon’s
gravity pulling on Earth.
the regular rise and fall of
the ocean’s surface
Ocean water is pulled
toward those areas of
Earth closest to the
moon.
causes erosion of beaches
