Earth and Plate Tectonics
O/A
1. Put the following list of scrambled events relating to
the earths geologic history in the correct order from
the beginning.
-amphibians, ozone forms, mammals, anaerobic
prokaryotes (photosynthetic cyanobacteria), earth
forms, fishies, eukaryotes, largest mass extinction in
history, reptiles, coal forming swamps form
(carboniferous period), oxygen levels rise, pangaea
2. What do you know about plate tectonics???? (brain
storm and bullet point list)
3. Think of one earthquake, volcano, and tsunami event
that have taken place on earth and describe it. Tell
what type of geology lead to each event.

plate tectonics
divergent, convergent
Composition of earths crust
Thingvillur, site of one of the earliest
parliamentary meeting places in western
civilization, and the one place where the MidAtlantic Ridge appears above ground. The
North American and European tectonic plates
are moving apart an average of two
centimeters a year. We could move from one
continent to the other in a few steps
Mid Atlantic ridge passing thru Iceland
Himalayas
Mt St. Helens
Geologic Timeline Presentations
• As a group, brainstorm and come up with three
concepts you learned from this activity.
• Each person in the group will share at least one of
the concepts
• Concept one: an analysis type of concept, where you
have analyzed the information and come up with an
understanding
• Concept two: make this a compare and contrast type
of idea that you learned.
• Concept three: this should be where you either make
a prediction or you can make an assumption
The Earth’s Tilt and how it creates seasons!
Spring
(sun aims directly
at equator)
Summer
(northern hemisphere
tilts toward sun)
Bill nye seasons
Winter
(northern
hemisphere
tilts away
from sun)
O/A
Please put the following phrases in order,
they are out of order.
-creates differences in air
temperature/pressure
-creates biome patterns
-determines air and ocean currents
-drives climate patterns
-incoming solar radiation is uneven due to
the earth’s tilt
1. Incoming solar radiation is uneven due
to the Earth’s tilt
2. Creates differences in temperature and
pressure
3. Determines air and ocean currents
4. Drives climate patterns
5. Creates biome patterns

INSOLATION-Measure of solar
radiation energy received on a given
surface area
Wind
Coriolis Effect
global wind video.flv
• Global air
circulation is
affected by
the rotation
of the earth
on its axis.
Observe an
animation of the
Coriolis effect over
Earth's surface.

CLIMATE: A BRIEF
INTRODUCTION
• Weather is a local area’s short-term (hours to days)
physical conditions (temperature, precipitation, humidity,
wind speed, cloud cover etc)
• Climate is a region’s average weather conditions over a
long time. (temp and precipitation) five factors that affect climate.lnk
– Latitude, elevation, prevailing wind direction,
topography, and ocean currents, help determine
climate.
Earth's Climate
Observe an animation of land and sea breezes.

•polar climates can be
observed at lower
latitudes, you just need to
increase your elevation, as
one would ascending a
mountain chain-->
Ocean Currents:
Distributing Heat and Nutrients
• Ocean currents influence climate by distributing
heat from place to place and mixing and
distributing nutrients.

Topography and Local Climate:
Land Matters
• Interactions between land and oceans and
disruptions of airflows by mountains and
cities affect local climates.

Apes Review Bluff
• 1. Name one place on the planet where a
major tsunami has occurred
• 2. Name one place where a cold water current
is found
• 3. Name one place where a subduction zone
can be found
• 4. Name one place where two land plates
come together to form a mountain range
• 5. Put the following events in order:
Mammals, amphibians, fish, ozone forms,
oxygen levels rise, photosynthetic bacteria
Review continued
• 5. what event is thought to have caused a
major extinction several million years ago?
• 6. how did the above event cause mass
extinction?
• 7. What causes seasons….must explain the
whole phenomenon to get points
• 8. how do the northern latitudes get warmth?
• 9. how would a volcanic eruption influence
the earth’s climate?
• 10. how does temperature and precipitation
change as one increases in latitude?
Review continued
