What rock type is made up of many different layers, which can appear to be different in their colors? "Cake Rocks"
A. Sediment
B. Metamorphic
C. Igneous
D. Sedimentary
What is D. Sedimentary.
Sedimentary rocks are formed from many layers of sediment, and these can also contain fossils.
This is the study of earth's physical structure and substance, its history, and the processes that act on it.
A. Geology
B. Geography
C. Geothermal
D. Geocentric
What is A., Geology.
Remember that geo is "earth", and logy is the "study of".
Which of the following energy types are NOT part of the changes of Earth?
A. Electrical Energy
B. Thermal Energy
C. Radiant Energy
D. Heat Energy
E. Mechanical Energy
What is A., C., and E.
Both Thermal and Heat are the same and are the energies most responsible for Earth's changes.
True or False. Erosion is when rocks do not move, instead they are broken into pieces at their original spot and only by wind.
What is False.
Erosion is when rocks are moved to a new place. This is also done by wind, water, and ice which also weathers rocks as well.
Which of Earth's layers is the layer that we live and walk on, and is only around 25 miles thick?
What is the Crust.
What type of rocks are gneiss, marble, slate, and schist that are exposed to intense heat and pressure?
A. Igneous
B. Metamorphic
C. Sedimentary
D. Fossils
What is B., Metamorphic.
These rocks are all created by intense heating and pressure, they "morph" due to all these factors.
This boundary type can cause earthquakes on land, or create tsunamis underwater?
What is a transform boundary.
Remember a transform boundary are two plates that rub against each other causing intense friction and heat buildup.
What does this picture show.
What is the rock cycle.
Remember this shows how the three rock types can be changed into each other, and be broken back down into magma and sediment.
Which of these layers is the oldest? And why?

What is bedrock, and it is the oldest because it is the furthest down in the soil which means it was created/formed at a time longer ago.
Which layer of Earth is pressurized into a molten solid, and is supposedly as hot as the surface of the sun?
What is the inner core.
The inner core is so intensely pressurized that the liquid nickel and iron are almost solidified.
Which rock type might include examples such as pumice and obsidian?
What is igneous.
These rocks are created by lava that cools and crystallizes.

Which boundary type is one that comes together or collides?
What is a convergent boundary.
The crack or line between two blocks of rock is called what?

What is a fault line.
Remember these are the cracks found between two plates where the boundaries collide, separate, and slide.
What is weathering.

True or False. The mantle is the thinnest layer, and is made up of moving liquid nickel and iron.
What is False.
The mantle is the thickest layer and is made up of molten magma and rock.
True or False. The theory that the outer most layer of the Earth is divided into plates that float upon a molten layer is called plate tectonics.
What is True.
Remember most of these plates are individual for each continent, but there are other also.
True or False. Divergent boundaries do not cause trenches and vallies to be formed.
Remember that divergent boundaries pull away from each other and cause vallies on land, and oceanic trenches in oceans.
This is the scientific tool used to measure the intensity or magnitude of an earthquake?

What is a seismograph.
Which of the following are when rocks and sediment are dropped to create new landforms?
A. Weathering
B. Sedimentary
C. Erosion
D. Deposition
What is D., Deposition.
Deposition is when rocks/sediment are "dropped". Like when you "drop off" your money at the bank to be deposited.
![]()
On what layer would you find fossils?
What is the crust.
Metamorphic rocks are created by what two factors?
A. Compaction and Cementation
B. Heat and Pressure
C. Erosion and Drifting
D. Crystalization and Fragmentation
What is B., Heat and Pressure.
The theory that millions of years ago the Earth's continents were connected into a single land mass is called?
What is Pangea.

A scientific tool used to identify organisms or objects (like plants, animals, or rocks) through a series of paired, opposing choices is called a _____?
A. Hypothesis
B. Dichotomous Key
C. Theory
D. Seismograph
What is B., Dichotomous Key.
Remember these are used to determine what a sample or organism might be by making choices.

Rocks are made up of one or more what?
A. Minerals
B. Atoms
C. Molecules
D. Compounds
What is A., minerals.
The outer core is made up of two metal elements, which are they?
A. Iron and Coal
B. Nickel and Steel
C. Iron and Nickel
D. Copper and Silver
What are C. Iron and Nickel.
Both the inner and outer cores are made up of the elements Iron (Fe) and Nickel (Ni).
