Layers of the Earth
The outermost chemical layer of the Earth.
What is the Crust?
An example of something that can cause rock to be weathered.
What is wind, ice, plants, acid, moss, water, animals, etc?
This is how old the universe is thought to be.
13 to 14 billion years old.
The smallest level of ecological organization. A single living thing.
What is an organism?
A chain of volcanoes and plate boundaries that circles the pacific ocean.
What is the Ring of Fire?
Name one piece of evidence we use to study the layers of the Earth.
What are seismic waves, Earth's magnetic field, or meteorites. (also lava samples)
Rocks being broken down into smaller pieces by physical or chemical means.
What is weathering?
Light and sound both behave like these fundamental shapes.
What are waves?
Things that are not living and were never alive are considered this.
What is abiotic?
A period in Earth's early history when cyanobacteria produced so much oxygen that nearly all life on Earth went extinct.
What was the Great Oxygenation Event?
The scientist that proposed the theory of Continental Drift.
Who is Alfred Wegener?
Particles that have been weathered being moved to another location by wind, water, etc.
What is erosion?
This was the scientist that discovered the phenomenon of Red Shift. (and also has a space telescope named after him)
Who is Edwin Hubble?
The level of organization that includes all living things and their habitats on Earth.
What is the biosphere?
A supercontinent that broke apart 300 million years ago.
What was Pangaea?
This is the plate boundary that usually has the most earthquakes.
What is a transform boundary?
Organic material on the surface of soil will become this substance as it decays.
What is humus?
These are the two light elements that make up 98% of matter in the universe.
What are hydrogen and helium?
A species that holds an ecosystem together. They have a large impact relative to their abundance.
What is a keystone species?
This rock type mostly makes up Oceanic crust.
What is basalt?
This is the layer that generates Earth's magnetic field.
What is the outer core?
Eroded sediment eventually stops moving and settles in this process.
What is deposition?
Energy left over from the Big Bang is known as this.
What is Cosmic Microwave Background Radiation (CMBR)?
A relationship between two different species.
What is symbiosis?
The African Rift Valley is an example of this type of plate boundary.
What is a divergent boundary?
