What stands out on this map?

Which words do you know, and which do you need help with?

Tectonic Forces

Earthquake Tsunami

Volcano Spreading Building

Lithosphere Subduction Mountain

How do “tectonic forces” affect a region?

THE HESS CONVECTION CURRENT ‘SLAB-PULL’- ‘RIDGE PUSH’ MODEL

Continents pushed apart by ‘Ridge-Push’ Subduction of oceanic Crust by ‘Slab Pull’Magma

Ridge-Push by diverging convection currents

Subduction by converging convection currents

Continental Crust pulled over the Oceanic Crust

weather?

Let’s see what we know…

Which are you ready to answer, and which do you need a peek?

Tectonic plate movement may be caused by all of the following EXCEPT—

A slab pull

B ridge push

C convection

D magnetism

All of the following are tectonic forces that shape the surface of the earth EXCEPT—A subductionB spreadingC transformationD transpiration

Let’s see what we know…Since you could answer the last

question, can you answer this one?

The Middle East consists of mountains, upland plateaus and valleys. These physical features are the result of:

A erosion

B tectonic forces

C deposition

D weathering

The same tectonic force, many continents…Let’s look again at “Tectonic Forces”

Which are you ready to answer, and which do you need a peek?

Because of its location along the "Ring of Fire," Japan is particularly susceptible to which of the following hazards?

F earthquakes and volcanoes

G floodings and droughts

H monsoons and floodings

J earthquakes and tornados

The Pacific Islands in the Ring of Fire are affected by all of the following except —A volcanoesB earthquakesC tsunamisD tornadoes
