G12 Earth Science Revision Quiz

What was the main evidence that supported the theory of continental drift?

• The shape of the continents looked like they could fit together like a puzzle.

• Fossils of the same plants and animals were found on different continents.

• Similar rock types and ages found on separate continents

• All of the above.

Which of the following best describes the theory of continental drift?

• The continents have always been in their current positions.

• The continents were once joined together in a single supercontinent.

• The continents have moved randomly around the globe throughout history.

• The continents are static and do not move at all.

A geologist found this fossil on a field trip. Which type of fossil did the geologist find?

• Trace fossil

• Mold fossil

• Petrified fossil

• Mineral Replaced fossil

What is this technique and how does it work?

• Sonar technique that uses sound waves to map or locate objects in the surrounding environment)

• Magnetism which measures the magnet fields of different rocks

• Radar to find nearby sea animals

What is the main advantage of using sonar technology in mapping the seafloor?

• It can provide high-resolution images of the seafloor.

• It can measure the temperature and salinity of seawater

• It can detect and classify different species of marine life.

• It can collect samples of seafloor sediment for analysis

Select all the ways that can be used for absolute age dating

• Tree rings

• Ice cores

• Law of superposition

• Radioactive Isotops

• Cross cutting relationships

Answer explanation

Law of superposition and cross cutting relationships are forms of relative age dating.

The image shows a mid ocean ridge. Which location has the youngest rock

• X

• Y

• W

• Z

The symbols found on the map below indicate where fossils have been found in the same layer of sediment. Each unique symbol represents the fossil locations of a particular species.

• Similar fossil types are never found on different continents.

• The continents' locations have remained constant throughout time.

• Each continent has completely unique plant and animal life.

• The continents were once connected to each other.

List three types of evidence Wegener used to prove his continental drift theory

• Continental fit

• Fossil evidence

• Rock evidence

• Plate movement

The principle where the oldest rocks are on the bottom and younger layers are above it is called

• Superposition

• Cross-cutting relationship

• Inclusions
