Q2 PMA Review (Rock Cycle and Fossils)

What is the name given to the one "Super continent"?

• Pangaea

• Superuno

• eine Welt

• Derosen

Two plates composed of rock of similar density meet along a convergent boundary. Which statement describes what will happen where the two plates meet?

• The plates will rub against each other, causing shearing and creating fault lines in the interior of the plates.

• The plates will collide with neither plate subducting, causing the crust to pile up and form a mountain range.

• The plates will collide, and the compression will heat the plates, causing some of the plates to melt and form volcanic mountains.

• The plates will rub against each other, causing one plate to subduct underneath the other plate and forming a deep trench along the boundary

Which type of rock results from melting and cooling of magma?

• Igneous
• Metamorphic
• Sedimentary
• Extrusive

Which type of rock forms from extreme heat and pressure?

• Igneous
• Sedimentary
• Organic
• Metamorphic

A metamorphic rock changes into an igneous rock by what two processes?

• Melting and cooling
• Extreme heat and pressure
• Compaction and cementation
• Weathering and erosion

This rock formed when bits of other rocks became pressed into a solid. What type of rock is it?

• Sedimentary Rock
• Metamorphic Rock
• Igneous Rock

According to the law of superposition, the oldest fossils are found 

• At the top of the rock layers
• Near the bottom of the rock layers
• In the middle of the rock layers
• Somewhat near the surface

_{Which rock layer in the diagram seems to be the oldest?}

• F
• E
• B
• A

According to the law of superposition, which layer is the youngest?

• A
• B
• C

An archaeologist made the following diagram of a dig site. What can be said about the pottery as compared to the skull found in the site?

• The rock layer with the pottery is more recent than the rock layer with the skull.
• The rock layer with the skull is more recent than the rock layer with the pottery.
• The rock layer with the skull is approximately the same age as the rock layer with the pottery.
• The rock layer with the skull has an absolute date of 17,000 years.
