Past andFuture

Earth has elements heavier than lead. This is supporting

evidence for this to have happened before the formation of our

solar system.

C1 $100

What is a Supernova?

C1? $100

Comets are from this region of our solar

system.

C1 $200

What is the Oort Cloud?

C1 $200

http://astro.berkeley.edu/~conor/ay250/pluto.html

Asteroids are primarily from this region in our solar

system.

C1 $300

What is the Asteroid Belt?

C1 $300

http://www.semp.us/_images/biots/Biot443PhotoA.jpg

C1 $400

The hypothesis that Earth-like planets are

rare because they must be found in this

zone in the Galaxy and position in their solar

system.

What is the Habitable Zone?

C1 $400

http://www.star.le.ac.uk/edu/Extrasolar.shtml

C1 $500

The Earth’s Eccentricity (elliptical orbit), obliquity (tilt)

and precession (wobble) can be

correlated to the ice ages and warming periods between

C1 $500

What are the Milankovitch Cycles?

C2 $100

The Himalayas are an example of this type

of plate boundary

C2 $100

What is convergent plate boundary?

http://courses.unt.edu/hwilliams/GEOG_3350/examreviews/exam1images/Fg17_23c.jpg

C2 $200

The spreading on the Atlantic sea floor is a

type of this.

C2 $200

What is a diverging plate boundary?

http://www.whoi.edu/cms/images/lstokey/2005/1/v42n2-mativey3en_5727.jpg

C2 $300

These boundaries grind sideways

against each other.

C2 $300

What is a transform boundary?

C2 $400

The Super-continent that formed ~250 MYA

C2 $400

What is Pangaea?

Scotese, C.R., 2002, http://www.scotese.com, (PALEOMAP website)

C2 $500

In the theory of plate tectonics, the plates

are part of this, riding on the viscous asthenosphere.

C2 $500

What is the lithosphere?

What is Water?

C3 $200

This molecule.

C3 $200

What is carbon dioxide?

C3 $300

The three oxygen molecule that is formed by and

absorbs ultra-violet radiation.

C3 $300

What is Ozone?

http://blogs.nature.com/climatefeedback/Ozone_Molecule_VdW.png

C3 $400

The most important greenhouse gas.

C3 $400

What is water vapor?

http://udl.concord.org/activities/CloudActivity/images/cloud-in-air-wiki.jpg

C3 $500

This is what greenhouse gases

absorb.

Heat

C4 $100

The hypothesis that the Earth was struck

by a Mars-sized object and resulted in this.

C4 $100

What is the moon’s origin?

http://jeffreykishner.com/images/full_moon_large.jpg

C4 $200

Rock formed when it is melted and then

cooled.

C4 $200

What is Igneous Rock?

http://windward.hawaii.edu/facstaff/mccoy-f/lava2sm.jpg

C4 $300

Rock formed by heat and pressure.

C4 $300

What is metamorphic rock?

http://www.tuttomosaico.com/2005/images/TS-MARBLE-ALL1.jpg

C4 $400

Rock formed from particles of weathered

rock, cemented together with

minerals. Most fossils are found in this type

of rock.

C4 $400

What is sedimentary rock?

http://static.howstuffworks.com/gif/age-dinosaur-bones-2.jpg

C4 $500

This convergent boundary is how Mt.

St. Helens was formed (because of these two

types of plates).

C4 $500

What is the result of continental and oceanic plates

meeting?

http://www.alancolville.com/plates/cascades.jpg

C5 $100

This protects us from solar winds.

C5 $100

What is the magnetosphere?

http://en.wikipedia.org/wiki/Geomagnetic

C5 $200

How the sun has changed through time.

C5 $200

What is getting bigger and hotter?

http://www.tc.cornell.edu/~slantz/SPUR/SPUR97/sun_pictures/

C5 $300

This is the origin of our magnetic fields.

C5 $300

What is the metal liquid outer core?

http://science.nasa.gov/headlines/Y2003/images/magneticfield/world-pr.gif

C5 $400

The estimated age of life based on chemical

evidence.

C5 $400

What is 3.8 GYA (billion years old)?

http://www.sciencedaily.com/releases/2006/07/060721090947.htm

C5 $500

This had to form before life could survive on land.

Mass Extinctions

Final

The greatest extinction event in the

history of our Earth, estimated to have

killed about 99% of all life.

Final
