What was Wegner's 3 pieces of evidence for Continental Drift?

Fossils that matched on separate continents

continents seemed to fit together like a puzzle

Mountain ranges lined up if continents pushed together

Glacial scars in Africa

Tropical fossil evidence in Antarctica

Unit 2

100

sediment piles up as a result of this process

deposition

200

underground molten mixture

magma

300

Japan and New Zealand are a string of ______ ________called an(a) ________ _______

volcanic islands, island arc

400

How does subduction change rocks?

dense crust gets pushed down

crust moves into mantle and melts

heat and pressure changes it to metamorphic

500

Name the 7 (SEVEN) layers of the earth in order from the surface to the center

HINT:  include the three geologic terms that include other parts of the earth's layers

oceanic crust, continental crust, lithosphere, asthenosphere, mesosphere, outer core, inner core

Unit3

100

What are the 5 products of the rock cycle

igneous rock, metamorphic rock, sedimentary rock, sediment, magma

200

this type of igneous rock is formed beneath Earth's surface

intrusive rock

300

An area where material deep from within the Earth rises to the crust to form magma is called....

hot spot

400

Breaks in Earth's crust where rocks have slipped past each other are called....

faults

500

What are the 5 processes in the rock cycle

heat and pressure, compaction and cementation, melting, cooling, weathering and erosion

Unit 4

100

this is the assumption that geologic events and processes that happen today happened many years ago

uniformitarianism

200

this type of weathering involves a chemical change in another material

chemical weathering

300

this includes several processes that are cause material / sediment to move down hill

mass movement

3 contour line

500

list and describe the three processes that work together to change our Earth's surface

weathering - breaks down

erosion - carries away

deposition - drops into a new location
