Earth's History
The Earth is thought to be this old
What is 4.6 Billion years old?
The Earth's interior is divided into this many layers?
What is 4?
You have this many genes for each trait, like hair color
What is 2?
The name of the supercontinent meaning "all lands together"
What is Pangea?
Opposite charges will do this
What is attract?
Early in Earth's formation, the entire planet would have been this, a word meaning hot melted rock
What is Molten?
This layer found just below the Crust is made of a combination of solid rock and semi-molten rock
What is the Mantle?
These 2 terms refer to "strong" genes and "weak" genes
What are dominant and recessive?
Type of plate boundary where plates collide into one another and often form mountains/volcanoes
What is convergent?
This refers to the area around a magnet extending in all directions
What is a magnetic field?
This Law states that rocks and fossils are older in age as you move down in the crust
What is the Law of Superposition?
The liquid, molten outer core is composed mainly of these 2 metals that produce Earth's magnetic field
What are iron and nickel?
This combination of 2 dominant genes results in a blending of traits. Example: Red flower and white flower create pink flowers
What is Incomplete Dominance?
The "zone" or area where one tectonic plate is forces under another
What is subduction zone?
The area of a magnet where the field is the strongest
What are the poles?
This term refers to an event where more than 80% of all organisms die.
What is Mass Extinction?
This movement of hot rising molten rock and sinking of cooler rock, causes the tectonic plates to move
What is convection?
This quick genetic change or "mistake" is usually not good for an organism's survival
What is a mutation?
The boundary around the Pacific plate where most of the earth's volcanoes can be found
What is the Ring of Fire?
An Electromagnet is this type of magnet because is can be turned on and off
What is a temporary magnet?
This form of Absolute Dating can identify the exact age of a fossil
What is Radioactive Decay?
This term refers to volcanic rock forcing it's way through existing rock layers
What is an Igneous Intrusion?
Gene combinations that are the same, like DD for 2 dominant or dd for 2 recessive, are called this type of gene combination
What is Homozygous?
The 3 main types of volcanoes
What are Shield, Cinder Cone and Composite
Earth's magnetic field, along with charged particles from the sun, combine to create these illuminating events
What are Auroras or Aurora Borealis?
