3.1 Geosphere and natural pollution Humans interact mainly with the outermost layer called the crust
CHANGES IN THE LITHOSPHERE Made of several large, movable plates called TECTONIC PLATES that are naturally moving.
Boundaries: 1. Convergent - volcanoes 2. Divergent - volcanoes 3. Transform - EQ
Volcano natural pollution impacts Have natural carbon emissions into the atmosphere! Hurts the water quality Changes the temperature by blocking out the sun! Releases SO2 which causes acid rain and acidic bodies of water!
Deadly ash clouds
Earthquakes impacts EQ destroy existing structures. To rebuild this is a waste of resources. Also disasters destroy natural ecosystems.
Atmosphere System & Pollution The release of CO2 and other gases are causing Green house effect. This creates global warming! The ozone layer is thinning from some of this!
Troposphere = Layer of the atmosphere that touches the surface of Earth. Virtually all human activities occur in the troposphere.
Troposphere importance Has most of the gas molecules Has most of water vapor Most weather occurs here
Stratosphere Next layer above earth Contains: 90% of OZONE LAYER *.
Greenhouse Effect in the Atmosphere “Causes buildup of CO2, which traps sunlight, and causes warming and climate changes.” too much CO2 released from: organisms, volcanoes, and burning of fossil fuels.
Greenhouse Effect Example of humans changing the earth’s atmosphere! Loss of ozone Pollution in troposphere Volcanic eruptions
Hydrosphere Complete the ws on hydrosphere. Pg 77
Why water? Life on earth could not exist without water for obvious reasons! But….another thing large bodies of water does for the planet is retain heat! This keeps earth at a steady temperature instead of completely depending on outside heat!
These natural phenomenon will not be stopped, but must be taken into consideration when trying to lower emissions.
