How long does it take the Earth to
revolve around the sun?
365 ¼ days
How long does it take the Moon to
orbit the Earth?
About 29 ½ days
The Earth’s tilt on its axis gives us-
4 seasons: Winter, Spring, Summer
and Fall.
What causes the ocean tides to rise
and fall on Earth?
The gravitational pull of the moon.
The moon appears to change its
shape from Earth because the Moon-
Reflects the sun’s light.
A puddle of water forms after a
thunder storm. Later that day it
disappears. What process explains
why the puddle disappeared?
Evaporation
What part of this cycle is the main
source of energy for the Earth?
The Sun
In which part of the diagram is water
changing from a liquid to a gas?
Part 3
What part of this cycle is an example
of condensation?
The clouds forming.
The energy that causes water on the
surface of the ocean to turn into
water vapor comes from the-
Sun
How do some plants break large
rocks into smaller pieces?
The plant roots grow into cracks in
rocks, forcing them apart.
What happens to a rock when water
freezes in the cracks?
The rocks will crack and eventually
break apart.
What is the process called when soil
and rock are broken down and
carried away by wind and water?
Erosion
What is the process called when
wind, water, ice or living things wear
down and break apart rocks?
Weathering
Where do delta’s form?
At the mouth of rivers.
A student conducts an experiment.
She puts different types of soil in
four identical pots. Each pot has a
hole in the bottom. She puts the
same amount of water in each pot. A
different amount of water drains out
of each pot. Which would be the best
conclusion to draw from this
experiment?
Different soils have different
abilities to absorb water.
You did an experiment with four types of soil. Each soil had
a different particle size. You filtered the same amount of
water through each soil type. Which soil allowed the water
to flow through the fastest?
Soil C
What is the best type of soil for
growing plants?
Soil that has a mixture of humus,
sand, silts and clay.
Which type of soil is best for
“holding” water?
Clay
Soil that is poor for growing plants
can be improved by-
Fertilizer or Humus
Often when you look at a very old
statue of a person, part of the face is
worn away. What is the most likely
explanation for this change?
Weathering
Look at the weather map. How will the weather in
Toronto most likely change soon?
Toronto will probably become
colder.
Which state is currently experiencing
severe weather?
Florida
What happens to a rock when it is
weathered?
The rock is broken into smaller
pieces.
How long did it probably take the
river to form the canyon shown in the
picture?
Several centuries to millions of
years.
