What does a star’s color indicate?

• Its temperature

• Blue – hottest

• Reds- cooler

Why do astronomers put telescopes in space rather than on Earth?

• To avoid the interference of the atmosphere.

What are the two distinctions between the inner and outer planets?

• Terrestrial or rocky

• Gas Giants

H-R diagram shows what information about the stars?

• Surface temperature and the absolute magnitude

• (remember absolute is compared at same distance, apparent is how bright they appear to be from earth)

What is the composition of the atmosphere?

• 78% Nitrogen

• 21% Oxygen

• 1% trace gases (CO2, water vapor, etc.)

The type of precipitation that is formed by freezing in mid air.

• Sleet

How would you describe a cirroculumus cloud?

Cirro – high

Cumulus - puffy

An area where air masses meet and cause weather events.

• Fronts

• Named for who is moving:

cold front

warm front

stationary front

occluded front

Describe the job of an anemometer and a barometer

• Anemometer – measures wind speed

• Barometer – wind pressure (in millibars)

Why is the Earth’s inner core solid and the outer is fluid?

Although the inner core is hotter, there is more pressure, keeping it solid.

The outer core is more fluid and causes the earth to have a magnetic field.

What theories were combined to create the plate tectonics theory?

Continental drift (Pangaea)

Seafloor Spreading (mid ocean ridge and subduction)

Identify the motion each boundary makes:

Convergentdivergenttransform

• Convergent – comes together (compression)

• Divergent – pulls apart (tension)

• Transform – slips past (strike –slip)

Are the plates of the Earth still moving?

• Yes, at about a rate of 2 cm per year.

(that is how quickly average people’s fingernails grow)

Which type of crust typically subducts and why?

• Oceanic crust is less dense than continental crust, so when they bump into each other, oceanic subducts.

• Oceanic/oceanic – older denser stays up

• Continental/continental – form folds and mountains

Describe the differences between chemical and mechanical

weathering.

• Chemical is breaking down rock using chemical reactions

• Mechanical breaking down the rock using physical means

How are erosion and weathering different?

Weathering just breaks down the rock

Erosion moves the pieces away and deposits in another area.

Saltatation, abrasion, and deflation are all types of what kind of erosion?

• Wind erosion

What are the three types of rock?

• Sedimentary, metamorphic and igneous

Name 2 types of mass movements of soil or rock.

Land slidesMud flowsRock slidesCreep –(slow moving)

Can you identify the forces that caused this erosion?

• Water

Name two of the 4 types of wetlands

• Marshes –dominated by soft stemmed vegetation

• Swamps– woody plants

• Bogs -freshwater wetlands with spongy peat deposits, evergreen trees and shrubs, and a floor covered by moss

• Fens- grasses, reeds and wildflowers

The area where all the water drains into a certain sight (big

bathtub) • Watershed

Which of the following could hit you in the head here on Earth?

MeteorMeteoriteMeteoid

• Meteorite – this is a meteoroid after it has entered Earth’s atmosphere

AUDIO DAILY DOUBLECan you sing any words to this

song?

The sun is a mass of incandescent gas, a gigantic nuclear furnace. Where hydrogen was built into helium at temperatures of millions of degrees…

Who is energy man and how does he get here, dude?

• Energy “man” comes to earth on electromagnetic WAVES

• “rad”iation

• Convection

• Conduction
