Study Guide – Units 5 and 6
Test – Thursday December 17
How did sedimentary rock form?
WEDCC – Weathering (breaking rock into sediment), Erosion (moving
the sediment), Deposition (dropping the sediment), Compaction
(squeezing the sediment), Cementation (gluing the sediment)
How was this canyon formed?
V-shaped canyons – riVers
U-shaped canyons - glaciers
How was this delta formed?
River slows down and drops sediment at the mouth (where it enters
the ocean). Forms branches. Always growing.
How was this sand dune formed?
Blowing wind forms sand dunes.
Which of the following was formed by a glacier?
U-shaped valleys
Which of the following is an alternative energy?
BiG WiSH – Biofuel (corn  ethanol), Geothermal (heat from the
Earth), Wind (wind turbines), Solar (sun – solar panels), Hydroelectric
(dammed up river)
Which of the following is not an alternative energy?
Alternatives are BiG WiSH
How did coal form?
Huge plants died and fell in the swamp. Turned into peat. Covered
with layers of sediment. Heat, pressure, and millions of years turned it
into coal.
How did oil and natural gas form?
Phytoplankton (microscopic) in the oceans, lakes, and seas died and
fell to the bottom. Covered with layers of sediment. Heat, pressure,
and millions of years, turned them into oil and natural gas.
Which of the following is a fossil fuel?
FF = CON non – Coal, Oil (petroleum), and Natural Gas
Where would you find a hydroelectric plant?
On a huge river
Describe geothermal energy.
Heat under ground. Buildings will have pipes underground.
What is a creek? What kinds of plants and animals would you find
around a creek?
A small, small river. Trees with leaves, fish.
In what type of environment do ferns like to grow?
Warm, humid environments
What do fossils tell us?
1. Types of plants and animals that lived in the past
2. What the area was like (environment, habitat) – was it a desert,
swamp, ocean, jungle, forest, etc).
