What else can I help you with?
Why is the ocean floor expanding?
Because of sea-floor spreading caused by the mid-ridge
Is the analysis of seafoor sediments evidence of sea-floor spreading?
Not really but sea floor sediments thickness increase with increased distance from spreading centers which is good evidence. Other evidence such as magnetic reversals, temperature, dating methods provide the best evidence of seafloor spreading
What three types of evidence provide supporting of sea floor spreading?
Seismic Waves, Rock formations, and the shapes of the continents over time
What are three types of evidence from the sea floor that prove the existence tectonic plates?
Earthquakes along the seafloor, tsunamis, and changed water movements.

How magnetic reversals provide evidence for sea floor spreading?
Because of the stripes at the sea floor which are magnetic minerals
What three types of evidence provided support of the theory of sea-floor spreading?
three are : eruptions of molten material magnetic stripes in the rock of the ocean floor and the ages of the rocks themselves :)

What is sea floor spreading and what evidence do we have to prove it is happening?
Magnetic minerals on the ocean floor.
What Three types of evidence from the sea floor that prove earths tectonic plates move?
Earthquakes along the seafloor, tsunamis, and changed water movements.
What is used as evidence for sea floor spreading?
Magnetic reversals
What three pieces of evidence for Wegener's theory came from the sea floor?
seafloor spreading, age of the sea floor and ocean trenches.
