UNIT 2 EARTH’S IMPACT ON HUMANS
GOALS • Colorado State Standards • 3.1 Students know the physical processes that shape Earth’s surface patterns • 5.2 Students know how physical systems affect human systems
BIG IDEAS EARTH’S IMPACT ON HUMANS Essential Question: How does the earth impact humans and how do they respond?
Hurricanes • A tropical cyclone(or hurricane) is a storm system characterized by a large low-pressure center and numerous thunderstorms that produce strong winds and heavy rain • They are also able to produce high waves and damaging storm surge as well as spawning tornadoes
Eye of a hurricane Hurricane Katrina, New Orleans
Hurricane Emily, Yucatan Peninsula, Mexico
Volcanoes • A volcano is an opening, or rupture in a planet's surface or crust, which allows hot magma, ash and gases to escape from below the surface
Monsoons India’s climate is dominated by monsoons. The term monsoon refers not only to the summer rains but to the entire cycle that consists of both summer moist onshore winds and rain from the south as well as the offshore dry winter winds that blow from the continent to the Indian Ocean.
Tectonic Activity • Earth processes which result in the creation and deformation of magma and rock • This includes earthquakes and the folding and faulting of mountains Fault block mountains Folding of mountains
Erosion • removal of solids (sediment, soil, rock and other particles) in the natural environment • Erosion is distinguished from weathering, which is the process of chemical or physical breakdown of the minerals in the rocks
Glaciation • A glacier is a mass of ice which moves over land • process of glacier growth and establishment is called glaciation Aletsch Glacier, Switzerland, the largest glacier in the European Alps Perito Moreno Glacier Patagonia Argentina
Mouth of the Schlatenkees Glacier near Innergschlöß, Austria. The Baltoro Glacier in the Karakoram Mountains, Pakistan. At 62 kilometres (39 mi) in length, it is one of the longest alpine glaciers on earth
Vocabulary • http://en.wikipedia.org/wiki/File:Earth-crust-cutaway-english.svg • Atmosphere– surrounds and protects the Earth; provides materials that allow the Earth to support and sustain life • Troposphere –this layer contains half of the Earth's atmosphere. Weather occurs in this layer. This is the layer in which we live.
Stratosphere - This layer is the second closest to the Earth and also contains a special chemical we call ozone (O³); Many jet aircrafts fly in the stratosphere because it is very stable. Also, the ozone layer absorbs harmful rays from the Sun. • Mesosphere - Meteors or rock fragments burn up in the mesophere. • Thermosphere - the hot sphere; extends into outer space; begins about 80 km above the Earth
Biosphere- global sum of all the world's ecosystems. It can also be called the zone of life on Earth
Lithosphere- includes the crust and the uppermost mantle, which constitute the hard and rigid outer layer of the planet The tectonic plates of the lithosphere on Earth.
Hydrosphere -describes the combined mass of water found on, under, and over the surface of Earth The movement of water around, over, and through the Earth is called the water cycle, a key process of the hydrosphere.
This unit will focus on Earth’s impact on humans • You are to think about how humans respond to these different conditions and what our response is • You will need to be able to analyze geographic information using relief maps, satellite images and photographs
