E. All the above
200
What is seafloor spreading?
Tectonic plates on the seafloor are slowly spreading apart.
300
What type of plate boundary causes volcanoes?
Convergent AKA "Subducting"
300
Sedimentary rocks are made from...
a. magma from volcanoes
b. layers of sand, plants, animal fossils
c. igneous and metamorphic rock
b. layers of sand, plants, animal fossils
300
Which is an example of physical weathering?
A. Oxygen reactions
B. Acid rain
C. Widely swinging temperature changes
C. Widely swinging temperature changes
300
Erosion can be caused by what kind of weathering? Must be able to name at least 2
1. Wind 2. Ice 3. Water 4. Gravitational pull
300
What is a Tsunami and what causes it?
A Tsunami is a giant wave caused by earthquakes.
*Extra 100 points if tectonic plates are mentioned*
400
What causes earthquakes? (Think about hand movements we have learned)
Plate tectonics shifting/slipping past each other at a fault.
*plus 200 points if you mentioned the word FAULT*
400
True or False:
The rock cycle only happens 1x per rock?
False: the rock cycle is an ongoing process of change in which rocks are created, destroyed, and recreated
400
When water freezes/ expands into cracks in rocks and causes rocks to split, this is called what?
Ice wedging
400
Which is an example of weathering?
a. The Grand Canyon
b. the rug in a living room
c. a ripped piece of paper
a. The Grand Canyon
400
What are dome mountains?
Explain what causes them to form.
Mountains with rounded tops. They are formed when magma pushes upward into the Earth's crust and cools (causes a dome shape).
500
What are the two types of tectonics plate boundaries?
Oceanic and continental
500
What is deposition?
Deposition is when particles are carried by water, wind, ice, and deposited into a new location.
500
Give an example of how weathering could be destructive to landforms.
Weathering may include violent storms, such as a hurricane, or flood. These events or occurences may have long lasting effects.
500
How does water cause erosion?
Flowing water picks up sediments and carries them to new locations.
500
These are the deepest places on the planet. These are formed when one tectonic plate slides under another, and the seafloor dips down to create valleys.
Ocean trenches
