What is the difference between Chemical Weathering and Mechanical Weathering?
Mechanical Weathering is the only type of weathering that breaks compounds down into smaller components
Chemical Weathering is the only type of weathering that breaks compounds down into smaller components
Chemical Weathering causes a chemical change in a compound, changing it to another, different compound.
Mechanical Weathering causes a chemical change in a compound, changing it to another, different compound.
What appropriately sums up the process of Frost Wedging?
Water works its way into cracks, freezes, then thaws, then re-freezes. Over time, this widens a crack until ultimately, the rock breaks.
Ice is wedged between a hole in a rock, and force is applied with a hammer to force the rock apart from a weak point.
In damp areas, in the morning, frost creeps into cracks in the Earth and slowly splits it further apart
The process by which icicles form and create cracks in the crust of the Earth.
Which of the following is NOT a weathering agent?
Wind
Water
Acid
Fire
Which of the following is NOT a factor that influences how quickly a compound weathers?
Time
Climate
Composition of the material being weathered
Agent
Color
Sometimes, the roots of trees will find nutrients in cracks in rocks. The roots will move into the cracks, and after gaining nutrients, the roots grow bigger. This splits the crack wider. This is an example of...
Chemical Weathering
Mechanical Weathering
Tree Weathering
Split Weathering
When Iron-heavy rocks are exposed to the oxygen in water and air, a chemical process called oxidation occurs. What is this an example of?
Mechanical Weathering
Chemical Weathering
Oxygen Weathering
Hydro Weathering
What are the four main layers of the Earth?
Crust, Mantle, Outer Core, Inner Core
Crust, Mantle, Inner Core, Magnesium Sphere
Mantle, Outer Crust, Inner Cord, Ocean
Crust, Outer Core, Inner Core, Continent
Which of the following layers of the Earth is INCORRECTLY matched with its physical state?
Crust-Solid
Mantle-Liquid
Outer Core-Liquid
Inner Core-Solid
What methods did scientists use to discover that the outer core is liquid?
Scientists didn't discover that the outer core is a liquid, because it is a solid.
Scientists were able to successfully dig through the mantle to the outer core and saw it with their bare eyes.
Scientists used Earthquakes and the resulting seismic waves to discover that the outer core was liquid
Scientists studied the patterns of burrowing animals to discover that the outer core was a liquid.
What property of waves was instrumental in discovering what the inside of the Earth was composed of?
Reflection
Refraction
Discontinuity
Revolution
A place on the crust of the Earth where no seismic waves are recorded is called a...
Refraction Zone
Shadow Zone
Blank Zone
Seismic Zone
True or False
The shadow zones for S-Waves and P-Waves perfectly line up.
True
False
The Inner and Outer Core are composed primarily of...
Iron and Nickel
Calcium and Magnesium
Iron and Copper
Copper and Nickel
The boundary between two mediums of different densities is called a...
Transform Boundary
Discontinuity
Boundary Barrier
Refraction Boundary
There is a discontinuity between which two layers of the Earth?
The Crust and the Mantle
The Mantle and the Outer Core
The Outer Core and the Inner Core
There is a discontinuity between all different layers of the Earth
What is the layer of Earth that we walk on?
(2 Answers)
Lithosphere
Crust
Mantle
Asthenosphere
What is the innermost layer of the Earth?
Crust
Mantle
Outer Core
Inner Core
There is an electromagnetic field around the Earth (it's how compasses work!). What do scientists hypothesize is the reason why?
The Outer and Inner Cores are made of Iron and Nickel
The satellites that NASA has launched into space
The Outer and Inner Cores are made out of Calcium and Nickel
The metals in the crust are magnetic enough to create a magnetic field by themselves
What do Mechanical Weathering and Chemical Weathering have in common?
They both break a large material into smaller materials
After both types of weathering, the material is chemically identical to what it started as
After both types of weathering, the material is chemically different to what it started as
There are no commonalities between Mechanical and Chemical Weathering
Which type of seismic waves do NOT move through liquids?
P-Waves
S-Waves
Surface Waves
T-Waves
