What is Paleontology?
Pushing up of Earth's crust by forces within Earth
Scientific study of fossils
Identical or Consitent
Taking place, changing, moving, etc., by small degrees or little by little
Put in order the divisions of time.
Era, period, epoch, eon
Eon, period, era, epcoh
Epoch, eon, era, period
Eon, era, period, epoch
What is Pangaea?
Huge continent that once existed that has since broken up
Point where tectonic plates touch or meet
Something that can prove or disprove an idea or theory
Pushing up of Earth's crust by forces within Earth
Process in which one lithospheric plate slides under another.
Uplift
Subduction
Convection
Transform
Evidence that supports the Continental Drift Theory.
There were fossils of mesosaurus on different continents but animals cannot swim.
The continents never drifted.
There were similar glacial deposits on several continents.
There was once life on Antartica which means that Antarctica was closer to the equator.
Why do scientists use SONAR?
To find treasure, fossils, frozen glaciers.
To locate volcanos.
To cummunicate with animals.
To measure the distance from the surface to the ocean floor.
Pushing up of Earth's crust by forces within Earth.
Subduction
Uplift
Tectonic Plates
Plate Boundary
Who's theory was it that the continents were all one large supercontinent and have separated over time?
Harry Hess
Alfred Wegener
Why do we use a geologic time scale?
To divide Earth's long history into smaller more managable parts.
To show the extinction of animals over the years.
To indicate how long it taks to walk around the whole world.
To show when animals first arrived on the Earth.
Seafloor spreading is when magma rises to the surface of the ocean floor, cools, hardens and creates new crust. This pushes older crust outward, away from the mid ocean ridges.
False
True
What is evidence?
A method of detecting and locating objects submerged in water by echo sounding.
Transfer of thermal energy in a fluid (liquid or gas) in which warmer fluid rises and cooler fluid sinks.
Identical or consistent.
Something that can prove or disprove an idea or theory.
Transfer of thermal energy in a fluid (liquid or gas) in which warmer fluid rises and cooler fluid sinks.
Subduction
Uplift
Convection
Gradual
How do you read a geologic time scale?
The divisions are created by visible change into eons, eras, periods, and epochs.
There is a timeline that represents each year.
The point where tectonic plates touch or meet.
Plate boundary
Convergent boundary
Divergent boundary
Transform boundary
What are tectonic plates?
The circular movement of magma in the asthenosphere - these cause the tectonic plates above them in the lithosphere to move.
Pieces of the earth’s rocky crust that rests and moves on the semi-liquid mantle
A place where edges of plates meet.
When plates move away from each other.
Remains, impression, track or other evidence of living things.
Evidence
Fossil
Convection
Uniform
What is seafloor spreading?
The circular movement of magma in the asthenosphere - these cause the tectonic plates above them in the lithosphere to move.
When two plates collide.
New seafloor being created.
When magma rises to the surface of the ocean floor, cools, hardens and creates new crust. This pushes older crust outward - away from the mid ocean ridges.
What happens when oceanic crust forms?
Uplift occurs which results in mountain building.
Subduction occurs and can result in volcano & island arcs.
A ____________ boundary forms when two plates diverge, or move away from each other.
Convergent boundary
Divergent boundary
Transform boundary
Plate boundary
A ___________ boundary forms when two plates slide past one another horizontally.
Transform boundary
Plate boundary
Convergent boundary
Divergent boundary
A __________ boundary forms where two plates collide.
Divergent boundary
Convergent boundary
Plate boundary
Transform boundary
An underwater mountain range, formed by plate tectonics in the middle of every ocean.
Tectonic plate
Seafloor spreading
Mid-ocean ridge
Crust
What happens when continental crust forms?
Subduction occurs and it can result in volcano and island acrs.
Uplift occurs which can result in mountain building
Who was Harry Hess?
A geologist who was a Navy ship commander who collected data about the ocean floor.
A German scientist who proposed the theory of continental drift.
