Endogenic & Exogenic Processes, Pangaea

Exogenic Processes

Very destructive, they are responsible fordegradation and sculpting the earth’s surface

Weathering

(Which Exogenic Process?) The process that breaks down rocks into smaller pieces.

False. They are Physical and Chemical Weathering.

(True/False) There is only one kind of weathering which is Physical Weathering

Physical Weathering

Rocks are physically broken into smaller pieces.

Physical

(Physical/Chemical Weathering) Release of Pressure

Physical

(Physical/Chemical Weathering) Growth of Plants

Chemical Weathering

The process of breaking down rocks through chemical changes.

Chemical Weathering

(Physical/Chemical Weathering) Water

Chemical Weathering

(Physical/Chemical Weathering) Oxygen

Chemical Weathering

(Physical/Chemical Weathering) CO2

Erosion

(Which Exogenic Process?) Rocks particles get carried away by wind,water, ice and gravity

EROSION BY WATER

(Which agent of Erosion?) It changes the shape
of coastlines. It constantly crashes against shores. It pounds rocks into pebbles and reduce pebbles to sand.

EROSION BY WIND

(Which agent of Erosion?) Erosion by ____ carries dust, sand, and volcanic ash from one place to another. ___ can sometimes blow sand into towering dunes

EROSION BY ICE

(Which agent of Erosion?) As glaciers move, they pick up everything in their path, from tiny grains of sand to huge boulders.

EROSION BY GRAVITY

(Which agent of Erosion?) ___ pulls any loose bits down the
side of a hill or mountain. This erosion is better known as Mass Movement.

Weathering is the breaking down of rocks.
Erosion is the transportation of those broken down rocks or sediments.

What's the difference of Weathering and Erosion?

Sedimentation

(Which Exogenic Process?) The natural process in which a material is carried to the bottom of bodies of water and forms to solid.

Mass Wasting

(Which Exogenic Process?) This refers to the downslope movement of rock and soil under the influence of gravity

Fall

(Classifications Of Mass Wasting) Rock fall

Slides

(Classifications Of Mass Wasting)
• Landslide
• Slump

Flow

(Classifications Of Mass Wasting)
• Mudflow
(Lahar)
• Earthflow
• Solifluction
• Creep

Fall

(Classifications Of Mass Wasting) It is the free-fall movement of detached individual pieces of rock.

Slides

(Classifications Of Mass Wasting) They occur whenever rock materials remain fairly coherent and move along a well-defined surface.

Flow

(Classifications Of Mass Wasting) This happens when rock materials are saturated with water and move downslope as a viscous fluid

True!

(True/False) A landslide is an example of 'Slides' Mass Wasting and is the movement of rock, debris or earth down a slope.

Slump (a kind of 'Slides' Mass Wasting)

A _ is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or rock layers moves a short distance down a slope. Movement is characterized by sliding along a concave- upward or planar surface.

Endogenic Forces

These are the internal forces that exist deep inside the Earth. They are called the "constructive forces"

Inside

Exogenic: Outside :: Endogenic:

Continent

A ____ is a large continuous mass of land conventionally regarded as a collective region.

Asia, Africa, North America, South America, Antarctica, Europe, and Australia

Enumerate the 7 Continents

False

(True/False) 'Pangaia' means “all the Seas”

Pangaea

Over millions of years, the continents of this enormous continent, gradually drifted apart and spread out to form the continents we know today.

Alfred Wegener

The Father of Continental Drift

CONTINENTAL DRIFT THEORY!

This theory suggests that, during the course of the planet's history, the continents have both moved toward and away from one another.
