Neutrons are not found in the atomic nucleus.
An electron ‘cloud’ surrounds each atom.
A proton ‘cloud’ surrounds each atom.
Protons and electrons are roughly equal in mass.
The Earth is closer to the sun during the summer months.
Cyclical activity on the Sun causes more radiant energy to be produced.
North America is tilted toward the Sun during the summer months.
Ocean water temperatures near the Equator influence North America during the summer.
The cyclical nature of tides
The predictable pattern of the seasons
The Coriolis Effect
The movement of tectonic plates
The the Sun
Most stars give off the same amount of light each year, and each star is mapped.
Stars can give off light for many years and never move in space.
Light travels a large distance in one year, and objects in space are very far apart.
About the same number of stars begin giving off light and dying each year
Volcanoes are most often located in the middle of tectonic plates
New volcanoes are located near inactive plate boundaries
Faults and volcanoes existed before there were any tectonic plates
Faults and volcanoes are often found at tectonic plate boundaries
Sediments are deposited where the floor spreads, causing volcanoes.
As the plates pull apart, magma moves to the surface, building ridges
Ocean water erodes the weak spots on tectonic plates, building ridges
Cold ocean water causes fissures that weaken the rocks, causing ridges
It will erode
It will become an igneous rock.
It will crystallize.
It will become a metamorphic rock
