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
GOALS Colorado State Standards 3.1 Students know the physical
processes that shape Earths surface patterns 5.2 Students know how
physical systems affect human systems
Slide 3
BIG IDEAS EARTHS IMPACT ON HUMANS Essential Question: How does
the earth impact humans and how do they respond?
Slide 4
Processes that Build up and Tear Down the Earth
Slide 5
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
Slide 6
Hurricane Katrina, New Orleans Eye of a hurricane
Slide 7
Hurricane Emily, Yucatan Peninsula, Mexico
Slide 8
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
Slide 9
Slide 10
Monsoons Indias 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.
Slide 11
Slide 12
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 Folding of mountains Fault block
mountains
Slide 13
Slide 14
Slide 15
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 rocksweathering
Slide 16
Glaciation A glacier is a mass of ice which moves over land
process of glacier growth and establishment is called glaciation

glacier in the European Alps

kilometres (39 mi) in length, it is one of the longest alpine
glaciers on earthBaltoro GlacierKarakoram

Vocabulary http://en.wikipedia.org/wiki/File:Earth-crust-
cutaway-english.svg http://en.wikipedia.org/wiki/File:Earth-crust-
cutaway-english.svg Atmosphere Atmosphere surrounds and protects
the Earth; provides materials that allow the Earth to support and
sustain life Troposphere Troposphere this layer contains half of
the Earth's atmosphere. Weather occurs in this layer. This is the
layer in which we live.
Slide 19
Stratosphere Stratosphere - This layer is the second closest to
the Earth and also contains a special chemical we call ozone (O);
Many jet aircrafts fly in the stratosphere because it is very
stable. Also, the ozone layer absorbs harmful rays from the Sun.
Mesosphere Mesosphere - Meteors or rock fragments burn up in the
mesophere. Thermosphere 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
Slide 22
Lithosphere 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.
Slide 23
Hydrosphere 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.
Slide 24
This unit will focus on Earths 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
