Landforms/Weathering and Erosion
a natural feature of the earth's surface.
the outermost layer of the Earth (what we walk on).
What is the crust?
True or False? Volcanoes ONLY occur at plate boundaries.
False
How old is Earth?
4.6 billion years old.
the preserved remains of (or traces of) dead organisms
What is a fossil?
Name one landform in the area.
Hill
River
List all 4 layers of Earth.

the gradual breakdown of rocks into smaller pieces.
What is weathering?
one of Earth's layers that is made mostly of iron.
What is the Inner Core?
List the 3 plate boundaries.
Convergent
Divergent
Transform
scientist that studies fossils.
What is a paleontologist?
the process in which Earth materials are worn away and transported by natural forces such as wind or water.
What is erosion?
layer between the crust and the outer core. Convection currents occur in this layer.
What is the mantle?
Which type of boundary is this?
Divergent Boundary
List the geologic time scale units from greatest to least
Eon
Era
Period
Epoch
the type of rock that fossils are found in
chemical weathering that effects statues, gravestones, and ecosystems.
What is acid rain?
True or False? The inner core spins faster than Earth and is as hot as the Sun.
True
the "ring" of volcanoes and earthquakes that circle the edge of the Pacific Ocean.
What is "Ring of Fire"?
Why is the geologic time scale important?
Because it provides us with a timeline of Earth's history (what Earth looked like at that time, the climate, the atmosphere, which plants and animals were living, etc.)
What do fossils tell us about Earth's history?
