Name that Layer...


Which layers make up the lithosphere?

1

A crust

B mantle

C inner core

D outer core

Multiple answer


Why wouldn’t the fossil of an ocean fish found on two different continents be good evidence of continental drift?An ocean fish could swim between continents so an ocean fish fossil found on two different continents would simply mean that the fish had migrated near one continent to another at some time.

A crust

B inner core

C mantle

D outer core

Multiple choiceWhich layer has the lowest temperature?


What kind of plates are colliding here?


The Continental Drift Theory was widely accepted when it first came out.

Harry Hess came up with the idea that the continents have drifted to their current location.

Alfred Wegener came up with the idea of sea-floor spreading

The Mid-Atlantic Ridge is an example of a convergent plate boundary.

A tension force is associated with a divergent plate boundary

The plates move on average 1 to 25 miles a year.

Convection currents have nothing to do with density.

Multiple choiceWhich layer takes up most of Earth's structure?


What are the scientific names for these layers?


Was Wegner’s Theory of Continental Drift widely accepted by other scientists when it was first published? Explain why. You should have at least two examples.

a. He did not have a driving mechanism to explain why or how the land moved.

b. He was meteorologist not a geologist.

c. He didn’t think it was his job to provide a mechanism.

d. People didn’t believe such large land masses could move across the ocean floor.

e. His evidence was based on other people’s findings and looked at as coincidence.

The layers of the Earth get denser as one travels downward towards the center of the Earth.

The plates are still moving today.

Less dense magma sinks, while more dense magma rises to create convection currents.

Convergent boundaries are associated with a compression force.

True False


Explain why there are few volcanoes in the Himalayas yet there are so many earthquakes.

Volcano Reason:There are few volcanoes in the Himalayas because it is a continental-continental plate boundary that results in uplift with little or no subduction zone to create volcanoes. There are also no hot spots in the Himalayas to create volcanoes.

Earthquake Reason: There are many earthquakes in the Himalayas because the continental-continental boundary is a convergent boundary that creates compression forces on the land resulting in the uplifting of the continents and earthquakes.


The Andes Mountains, the Himalayas and the Islands of Japan were all formed at convergent plate boundaries. Explain how the formation of the Andes Mountains, the Himalayas and the Islands of Japan are different. (Hint: Discuss the types of plates involved for each location.) Andes Mountains: The Andes Mountains were formed by a oceanic-continental plate boundary. The less dense South American (continental) plate is riding over the more dense Nazca (oceanic) Plate resulting a subduction zone, trench and volcanoes.Himalayas:The Himalayas were formed by a continental-continental plate boundary. The Indian or Indo-Australian Plate is colliding with the Eurasian Plate resulting in the uplifting of the continental crust to form the tallest mountains in the world. There are many earthquakes as a result of this uplifting movement.Islands of Japan:The Islands of Japan were formed by oceanic-oceanic plate boundaries. The Pacific Plate is colliding with the Eurasian Plate and the Philippine Plate is also colliding with Eurasion Plate creating a deep ocean trench/subduction zone and the Island Arc of Japan because the plates are trying to go down creating many volcanoes and earthquakes.
