Intro & Maps for $100

1.Geology

2.Astronomy

3.Oceanography

4.Meteorology

What is the name of our galaxy?

The Milky Way galaxy

Alfred Wegener is credited with the idea

of ???????

Continental Drift

What is the difference between a fracture and

a fault?

A fracture is just a crack in the ground, but a fault is when there is movement along the fracture.

What are the three main types of volcanoes?

1. Shield Volcano2. Cinder Cone Volcano3. Composite Volcano (aka stratovolcano)

What determines whether a rock is

igneous, sedimentary or metamorphic?

The way that it is formed.

Which metric unit would be appropriate to give the distance from Cary

to Greensboro?

kilometers

Which scientist invented the telescope?

Galileo

Earth’s many lithospheric plates float on the ?????

asthenosphere

Where is the foot wall of a fault located?

BELOW the fault

Mt. St. Helen’s is an example of which type

of volcano?

Composite Cone

What are the two types of igneous rocks?

Intrusive Extrusive

What process do scientists use to solve

problems?

Scientific Method

Our sun is in what phase of its life cycle?

Main Sequence Star

What is the action at a divergent boundary?

AND Give an example of where this

type boundary is found.

Plates are pulling apart.Ex. mid-ocean ridges

What does the hanging wall do in a reverse

fault?

The hanging wall moves UP.

Name & describe three types of mafic lava.

Pahoehoe – wrinkled, ropey Aa – sharp, jagged chunks

Pillow Lava – globs of lava that are extruded underwater

What determines the difference between the

clastic sedimentary rocks?

Size of the particles

ex. Large = conglomerateMedium = sandstone

Small = shale

Which branch of earth science studies meteors

that streak across the sky?

Astronomy

Explain the differences between a meteor, a

meteorite, and a meteoroid.

Meteoroid – located in spaceMeteor – has entered Earth’s

atmosphereMeteorite – has crash-landed

onto Earth

What features are formed at a oceanic-to-oceanic convergent boundary AND where could you see such a boundary?

Trench and a volcanic island arc

ex. Aleutian Islands andJapanese Islands

Name the three major earthquake zones?

1. Mid-Ocean Ridges2. Pacific Ring of Fire3. Eurasian-Melanesian Belt

Which types of tephra can be carried by the

global winds and distributed worldwide?

Volcanic dust and ash

What are the two ways that metamorphic rocks

can be formed?

Regional metamorphismContact metamorphism

A student wants to determine which color absorbs heat the most. The

experiment has many different colors of paper under a lamp and the

temperature of each is recorded.

Name the Independent Variable.Name the Dependent Variable.

Independent Variable:different colors

Dependent Variable:temperature

Name and explain the theory about how our

universe began.

The Big Bang Theory states that all the matter of our universe began in

one tiny point. There was some type of explosion and all that matter and energy was flung outward and created our expanding universe.

Name the three types of plate boundaries and give

the type of stress associated with each.

1. Divergent Boundary – tension2. Convergent Boundary – compression3. Transform Boundary -- shearing

Name at least three ways that earthquakes might

be predicted.

1. The ground tilting2. Small foreshocks3. Seismic gap theory

Explain the difference between a crater and a

caldera.

A crater is a funnel-shaped pit at the top of the volcano. A

caldera is a bowl-shaped depression created when the

walls of the crater collapse.

What is the difference between a foliated and

nonfoliated metamorphic rock?

Foliated has a striped (or banded) appearance.

Nonfoliated does not have stripes (or bands).
