Material behaviors of the earth's structure, i.e., rigid or ductile
The rigid lithosphere floats on the ductile asthenosphere
2 types of lithosphere
Oceanic: thin and more dense & continental: thick and less dense
Testable explanation for what you have observed
mass/volume. Or, how much/how big.
Attractive force between masses
Heat transfer due to light.
Heat transfer due to movement of material.
Heat transfer due to contact.
Age of Earth
4.5 billion years old
An object will float if an equal amount of mass of the supporting fluid is displaced.
Atoms of the same element that have different atomic masses. -- same # of protons but different # of neutrons
Number of protons in the nucleus. -- defines what element an atom is.
Number of protons + number of neutrons
The smallest unit of matter that has the properties of elements.
Atom with a charge imbalance. -- unequal # of protons and electrons.
Positively charged ion. -- more protons than electrons.
Negatively charged ion. -- more electrons than protons.
Outermost shell of electrons
An atomic bond between atoms in which valence shell electrons are shared. -- strongest atomic bond. -- water
An atomic bond formed by electrostatic attraction between ions of opposite charge when electrons are transferred. -- like NaCl, sodium chloride. -- two ions with opposite charge that hang out near eachother to appear charge balanced.
An atomic bond where electrons are freely shared among nuclei.
An atomic bond between the polar water molecule and other atoms/molecules.
A molecule that has an equal number of protons and electrons but an uneven distribution of electrons across the molecule.
