Science Chapter 6 Study Guide
I.
Inside Earth
Be able to label the layers of the Earth (crust, mantle, inner
core, outer core)
Which layer is the thinnest?___crust____________________
II.
Earthquakes
What causes earthquakes? Rubbing together of plates creates
energy that builds until it is released as vibrations or seismic
waves.
How do earthquakes help scientist find out about what is deep
inside Earth? Certain types of seismic waves travel through
liquid, solids, or both. So scientists have been able to use
earthquakes to help figure out the make up of Earth’s interior.
III.
Volcanoes
Label six volcano parts (lava, magma chamber, vent, ash
cloud, crust, side vent)
What causes volcanoes to erupt? The separation of the crusts
plates create openings for magma to escape.
How have volcanoes shaped Earth’s surface? Mountains and
islands.
IV.
Glaciers
How does a glacier form? When more snow falls in the winter
than melts in the summer.
How does a glacier move? The weight of the snow and force of
gravity causes the glaciers to move downhill.
How can glaciers change the land? Give examples of two
features left by glaciers. Glaciers act as a bulldozer, pushing
and scraping the land. Rounding and flattening leaves behind
hills and U-shaped valleys
V.
Weathering and Erosion
Name the four agents of erosion. Water, wind, gravity, glaciers
How can wind cause erosion? Wind can move loose soil or
sand, but it can also act like sandpaper or a sandblaster as it
blows these loose particles against rock.
What forces coastline changes? Waves beating against the
coast.
How can gravity and water change Earth’s surface?
Causes landslides and mudslides
What happens to form a delta? Running water drops particles
picked up along its journey at a river’s mouth and these
particles settle there.
VI.
Review questions
Name the five steps of the scientific method. Observation,
question, hypothesis, experiment, conclusion
Expain the ways the Earth, Moon, and Sun move around each
other.
The sun does not move, earth rotates on its axis as it revolves
around the sun, the moon revolves around earth.
