When looking for Fossils, these type of rocks are best for finding ancient life:
A> Igneous
B> Sedimentary
Sedimentary
100
Name a landform that occurs near plate boundaries
Volcanoes, mountains, islands, plateaus...

Intrusive or extrusive: which type is created below the Earth’s surface?
Intrusive
200
This rock is made from sand-sized particles that have been cemented together
Sandstone
200
These rocks form at the Earth’s surface from lava. They cool very quickly and have small (or no) crystals
Extrusive
Igneous
200
Geologists use these type of fossils to determine the age of rocks
Index fossils
200
This is the name for the area of the world where the majority of volcanoes are found
Pacific Ring of Fire
200
The outer layer of the Earth is known as:
Lithosphere
or...
Crust
300
Which epoch do we live in now?
Holocene
300
These invisible lines on the Earth are measured by how far North or South of the equator they are
Latitude
300
This mineral is composed of calcium, carbon, and oxygen. It fizzes when hydrochloric acid is introduced
Calcite
300
This is the volcanic material that is in molten rock under the Earth’s crust
Magma
300
This layer of the Earth is semi-solid. It starts with an “A”
Asthenosphere

Which is larger: an Era, a Period, or an Epoch?
Era
400
The edges of tectonic plates where earthquakes and volcanoes occur are called...
Plate Boundaries
400
True or False: Fossils can be found in igneous rocks
False
400
This occurs in molten, volcanic material that erupts from the Earth’s surface
Lava
400
True or False: Tectonic plate only exist below continents
False!
They're everywhere!

This is the solid rock that lies underneath the soil, oceans, and continents
Bedrock
500
The name for an imprint of an organism left in an Earth material (usually a rock)
Fossils

Choose 1: Which is NOT a reason there could be a gap in the fossil record?
Some environments aren’t suitable for fossilization
Lots of fossils we haven’t found yet
Some geologic events have destroyed fossils
Periods of time where no organisms died
D. Periods of time where no animals died...
Things are always dying!
500
When magma and lava solidify, this is the type of rock they produce
Igneous
500
Which of these rocks is an example of an extrusive igneous rock?
Sample B
Extrusive rocks cool quicky and have small (or no) crystals
