Impact of Geological Activities


Detrimental

  • Many on Earths geological activities can affect humans in adverse ways.

Landslides

Tectonic Activity

Earthquakes

Volcano

Home


Landslides

  • A Landslide takes place when a large amount of dirt or gravel breaks loose and begins to slide down an embankment.

  • For more information check out this site. Landslide safety

Predicting

Causes


Predicting Locations

  • Predicting a landslide is often very hard because we can not see the condition of the soil below the surface. Areas most at risk receive large amounts of rain fall and have hills/cliffs with a large angle of decent.

Back to Landslides

Home


Damage

  • Landslides can cause sever damage to houses and other man made items.

  • Landslides can not only destroy a foundation but also dump large amounts of soil on any objects below them.

Back to Landslides

Home


Causes

  • Landslides are often seen on cliffs or on hills with a large angle of decent. The common factor among all landslides are lose soil and moisture.

Tectonic Activity

The driving force behind all of Earth’s geo activity are the tectonic Plates.

Back to Detrimental effects

Home


Volcano

  • Volcanoes are created when the pressure of the magma under the surface and no longer be contained by the Lithosphere.

Benefits


Damage

  • There are many hazards associated with volcanoes.

Pyroclastic Flows

Lava Damage

Ash Rain

Return to Volcanoes

Home


Pyroclastic Flows

  • A Pyroclastic flow is essentially a land slide created by boiling mud and lava.

Return to Damages

Home


Lava Damage

  • The molten lava that comes from volcanoes is so hot it can cause trees to combust from many feet away.

  • Check out this website for more info!

Return to Damages

Home


Ash Rain

  • Ash rain is essentially the falling of hot ash from the sky. In the city of Pompeii the ash actually created casts of people.

Return to Damages

Home


Benefits

Despite all the damage a Volcano can create it is a natural part of the living earth and has some benefits to it as well.

Increased Land mass

Nutrients

Return to Volcanoes

Home


Increased Land Area

  • Lava crawls out into the ocean of the largest Hawaiian island constantly. This causes the island to grow each year by 6 feet!.

Return to Benefits

Home


Reintroduction of Nutrients

  • The Carbon Cycle is essential to human life.

Return to Benefits

Home


Predication of Volcanoes

  • The build up of Magma pressure under Convergent and Divergent cause volcanoes.

Return to Volcanoes

Earthquakes

  • If you hear a rumbling and a tumbling it might be an earthquake.

Back to Detrimental effects

Home


Locations most frequent

  • Most Earthquakes take place on plate boundaries.

Return to Earthquakes

Home


Causes

  • The frictions created when two plates rub together create earthquakes.

Return to Earthquakes

Home


Damage

  • The Lifting and falling of the ground below our feet.

  • Checkout this video  of the destructive power of an Earthquake

Return to Earthquakes

Home


Predication of Earthquakes

  • Very hard to do however scientist of several proposed ideas

Return to Earthquakes

Home


Beneficial

  • Many of Earths geological activities can benefit humans.

Resources

Energy

Home


Resources

  • The Earth provides us many of the essential resources needed in out lives.

Precious Metals

Industrial Metals

Return to Benefits

Home


Precious Metals

  • Many kinds of precious metals are mined from the earth including gold and platinum.

Jewelry

Electronics

Return to resources

Home


Jewelry

  • Gold and silver are used in jewelry

Return to Precious metals

Home


Electronics

  • Precious metals are used in many of today’s electronics. Such metals as gold and platinum are essential to a computer’s CPU.

Return to Precious metals

Home


Industrial Metals

  • Iron is also another invaluable metal to today’s society.

Buildings

Automobiles

Return to resources

Home


Buildings

  • Building foundations are mostly made from steel which is formed from iron.

Back to Industrial Metals

Home


Automobiles

  • Car frames are also usually made from aluminum which is mined from the earth.

Back to Industrial Metals

Home


Energy

  • Energy from the Planet

Thermal Energy

Fossil Fuels

Return to Benefits

Home


Thermal Energy

The earth provides humans with a great way to power our houses through thermal energy.

Clean

Cheap

Reusable

Return to Energy

Home


Clean

  • Thermal energy produces no waster other then steam.

Back to Thermal Energy

Home


Cheap

  • Once a thermal energy facility is built the upkeep is very minimal compared to the amount of energy produced.

Back to Thermal Energy

Home


Reusable

  • Unless the planet turns off this sources of energy will never quit

Back to Thermal Energy

Home


Fossil Fuels

  • Fossil fuels are actually the remains of creatures.

Economic Dependence

Pollution

Coal/Oil

Return to Energy

Home


Pollution

  • Fossil Fuels produce harmful gasses such as sulfur and co2. These gasses can cause a variety of problems like Global warming and acid rain.

Back to Fossil Fuels

Home


Economic Dependence

  • Without the constant supply of fossil fuels our economy would crash.

  • Research is currently being conducted into alternate forms of energy.

Back to Fossil Fuels

Home


Coal/oil

  • Coal and oil are both taken from the ground. Both are the remains of prehistoric organism that have decomposed into a fossil fuel.
