Quiz Scavenger Hunt Beneficial Detrimental By Sean Bresnahan Credits 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 Back to Detrimental effects Damages Home 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. Back to Landslides Home

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. Back to Detrimental effects Damages Prediction Home 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 Home

Earthquakes • If you hear a rumbling and a tumbling it might be an earthquake. Prediction Most frequent locations Causes Damages 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. Back to Fossil Fuels Home
