The Genesis Question: How did all life forms come to be in this earth?

Which theories best explain the origins of man and the earth?

How does geography shape human evolution and civilization?

How about 8, 10 billion in the next 50 years?

Can the earth keep up with 7 billion people?

Enduring UnderstandingThe study of man’s history would be

incomplete without first understanding his own origins and the larger environment around him, that is the Earth.

Geography serves as the foundation in shaping human culture and civilization.

Geography plays a vital role in forming the different countries of the world.

Man’s cultural development is a by-product of man’s willingness to survive in a changing environment.

Geo-Vocabulary Words Theory - A set of statements or principles devised

to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena.

Universe - All matter and energy, including the earth, the galaxies, and the contents of intergalactic space, regarded as a whole.

Galaxy - any of a vast number of star systems held together by gravitational

Solar system - The sun together with the eight planets and all other celestial bodies that orbit the sun.

Nebula - a diffuse cloud of particles and gases that is visible either as a hazy patch of light or an irregular dark region against a brighter background

Planets - celestial body larger than an asteroid or comet, illuminated by light from a star

ORIGIN OF THE COSMOS

Big BangTheory

• The universe was compacted into a cosmic ball that subsequently exploded with a big banginto everything that exists today. (i.e. space, time, matter and energy)

The universe goes througha tremendouslyhigh-speed risethat expands within a fraction of a second

The universe

came to bebecause of a colossal explosion

Creation a supreme being

(God) created the earth and the universe.

Creationists embrace the Bible not only for its religious content but also for its recording of history

“In the beginning God created the heavens and the earth”.

This belief is often summarized as the universe was built “by design” and not simply by chance as the big bang theory assumes.

ORIGIN OF THE SOLAR SYSTEM / EARTH

Nebular Theory

A nebula is a large cloud of gasesbelieved to be the remnants of a star which has exploded.

This mass rotates continuously while it shrinks and flattens due to the force of gravity

The different parts of the solar system were formed from this huge mass of cloud.

Text

Planetesimal Theory

1A star passed close to the sun. Huge tides were raised on the surface and these erupted matters were torn free (planetesimals)

2

Solar system was formed when a star collided with the sun

Gaseous Tidal Theory

A huge tidal waveraised on the sun by a force of gravity of a passing star

Solar system was formed when a star collided with the sun

Phase 1

Phase 2

Condensation

A. The solar nebula contracts and flattens into a spinning disk.

B. The large blob in the center will become the Sun. Smaller blobs in the outer regions may become jovian planets.

C. Dust grains act as condensation nuclei, forming clumps of matter that collide, stick together, and grow into moon-sized planetesimals.

ORIGIN OF THE EARTH / COUNTRIES

CONTINENTAL DRIFTAll continents were once

part of a supercontinent known as Pangaea (Pangea) which means all lands.

Divided into two: Laurasia (North) and Gondwanaland (South)

PLATE TECTONICSTectonics: to buildThe crust floats over a semi-molten layer.

The crust is broken up into large small pieces called plates

These plates are always in motion

There are 14 major continental and oceanic plates

When one plate collides with another, it may divide or “subduct” underneath the other.

Do you have clarifications?

Does everything make sense?
