Physial Science Quizz #2

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
