Chapter 9 Dynamic Earth

A way of determining the age of fossils by comparing them to fossils found in strata above and below is called

• fossil dating
• radiocarbon dating
• relative dating
• relational dating

The theory that states that Earth's continents slowly move about the earth's surface

• relative dating
• pangaea
• tectonic plates
• continental drift

Horizontal layers of sediment are called

• strata
• fossils
• rock
• lithosphere

A method used to date objects up to 60,000 years old, by measuring the amount of carbon-14 in the object is called

• relative dating
• radioactive dating
• radiocarbon dating
• relational dating

The thin outer layer of the earth is called the

• core
• crust 
• mantle 
• magma

The remains of once living organisms often preserved in sediment are called

• artifacts
• strata
• remnants
• fossils

The thick layer below the crust made of molten rock which is softer near the top and more stiff farther down is called the

• lithosphere
• ionosphere
• mantle
• outer core

The large irregular sections of the earth's crust which float on the mantle are called

• tectonic plates
• crustal plates
• mantle plates 
• core plates

Which of the following is an example of a trace fossil?

• dinosaur bone
• shell
• footprint left in sediment
• broken fossil of a fish

The movement of the earth's crust is caused by the 

• gravitational pull of the moon
• convection currents in the mantle
• spinning of the earth
• ocean currents
