What do you think the
inside of Earth is like?
What is Plate Tectonics?
The Early Earth and Plate Tectonics
I.
A.
The theory that Earth’s crust is divided into
sections and these sections are in constant
motion.
A.
Earth is divided into three layers- the crust,
mantle, and core.
1. Earth’s layers are arranged by their densities
Greatest density is at the
center of Earth.
Lowest density is at Earth’s
surface.
Crust- Earth’s outer layer. Also the thinnest layer
1. Solid rock that includes dry land and ocean floor.
2. 5- 100 km thick.
3. Two types- 1. oceanic crust = basalt, more dense
2. continental crust = granite, less dense
A.
A.
B.
C.
Layer between the crust & core
Mantle is Earth’s thickest layer.
Mantle is made up of very thick molten rock.
made up mostly of iron and nickel.
B.
Core extends from the bottom of the mantle to
the center of Earth.
C.
Mars could fit into Earth’s core.
"Journey to the Center of the Earth"
A.
A. Earth is divided into five main physical layers
1. Lithosphere- outermost, rigid layer.
Made of two parts.
a. the crust
b. the rigid upper part of the mantle

B. Asthenosphere- soft layer of the mantle on which
pieces of the lithosphere move.
1. made of solid rock that flows very slowly
C. Mesosphere- beneath the asthenosphere. Strong,
lower part of the mantle.
1. Extends from the bottom of the asthenosphere
to the core.
D. Outer Core- liquid layer of Earth’s core that
lies below the mantle
1. Surrounds the inner core.
E. Inner Core- solid, dense center of our planet

Bass tapeworms attach to the gills and intestines of
bass fish. These worms survive by taking nutrients
from the bass. What type of relationship does this
represent?
A. predation
B. parasitism
C. mutualism
D. commensalism

If you baked a giant pie and were moving it what
do you think would happen to the crust?
Pieces of Earth’s lithosphere that move around on
the asthenosphere.
1. The Earth’s plates are like pieces of a puzzle.
2. Plates can be either continental crust, oceanic
crust or both.

core? Pillow Lava - Lava Dive Hawaii

1. Seismic Waves- vibrations created by
Earthquakes that travel through Earth
2. When seismic waves travel through different
materials they travel at different speeds
