Earth's Structure
The inner core of the Earth is composed of:
Iron and Nickel
There are #______________ types of boundaries that geologists observe!!!
3!
_____________ _____________: Single, fixed column of magma that pierces through plates and produces volcanic eruptions!
Hot-Spot!
_____________________ is the removal of rock particles from a location.
Erosion
An organism is most likely to become a fossil if it has hard parts like _______________, _______________ or _______________. (Ex. Fish)
Shells, teeth or bones!
Periodic table symbols for Iron and Nickel
Fe and Ni
The Earth’s crust is divided into segments called ______________________.
Plates
The ___________________ is a string of underwater volcanoes and earthquake sites around the edges of the Pacific Ocean.
Ring of Fire
A Dust Storm is an example of what type of erosion?
A: Water
B. Wind
C. Ice
D. Gravity
Wind Erosion
Why are only a small amount of living creatures fossilized?
Most organisms are not rapidly buried.
Alfred Wegener,
Pangea
Earthquakes happen at _______________plate boundaries.
Transform
__________________ is an extremely active volcano in the Hawaiian Islands, and the most active of the five volcanoes that together form the big island of Hawaiʻi.
Kilauea
What are four types of erosion?
Water, Wind, Ice and Gravity
A _________________ or _______________ is unlikely to become a fossil because it lacks hard body parts for calcification.
Jellyfish, earthworm, squid, octopus
Define Molten:
Melted rock
At ___________________ boundaries, continents or ocean floors are spreading apart. As new crust forms it pushes the plates on either side of the boundary farther and farther away from each other.
Divergent
What is the difference between magma and lava?
Magma: Molten rock beneath Earth's surface
Lava: Molten rock above Earth's surface
What is deposition?
Deposition: When sediments are built up and laid down in new locations
The Arthropod family includes insects, spiders and crustaceans. In arthropods, such as insects, arachnids and crustaceans, ___________________, is the shedding of the exoskeleton (which is often called its shell), typically to let the organism grow.
Molting
The largest part of the Earth
Mantle
_____________________ is an extinct freshwater reptile which lived approximately 300 million years ago. His fossil remains were found on the eastern coast of South America and western coast of Africa.
Mesosaurus
The Hawaiian Islands were formed by a hot spot punching through the middle of the __________________ Plate.
Pacific
This is one of the world's most studied landforms. The ______________ ______________ was cut away by the flow and erosion of the Colorado River. It's rich, geologic landscape formed over millions of years by a combination of natural forces.
The Grand Canyon
