How does the age of rocks in the seafloor provide evidence of seafloor spreading?
The age of rocks gets progressively younger as you move away from the mid-ocean ridges, where seafloor spreading occurs. This supports the theory of seafloor spreading, as new crust is being formed at the ridges and then moves away from them over time. This process leaves a record of older rocks further from the ridges and younger rocks closer to them.
How does the age of seafloor bedrock vary with distance from a mid-ocean ridge?
The age of seafloor bedrock increases with distance from a mid-ocean ridge. At the ridge, the bedrock is young, as it is continuously being formed by volcanic activity. As it moves away from the ridge through the process of seafloor spreading, it cools and ages over time.
Is there evidence that seafloor-spreading?
Yes, there is evidence supporting seafloor spreading, including magnetic striping patterns on the ocean floor, the age progression of seafloor away from mid-ocean ridges, and the presence of hydrothermal vents along mid-ocean ridges that release magma from the Earth's mantle.
What sentence best describes the information provided by radiometric dating?
Age is based on fossils that are found in the rock.
How does seafoor age and magnetic clues support seafloor spreading?
Seafloor is youngest near the mid-ocean ridges and gets progressively older as you move away from the ridge. Magnetic stripes on the seafloor provide evidence of seafloor spreading, as they show alternating patterns of normal and reversed magnetic polarity that match the Earth's magnetic reversals over time. This supports the theory of seafloor spreading as new oceanic crust is created at the mid-ocean ridge and spreads outward.
Which statement best describes the national economy during the gilded age?

How does the age of seafloor sediments change with increasing distance from the ocean ridge?

Which statement least describes the state of the economy after the civil war?

What title best describes the current geologic age?

Which best describes the Victorian Age?

A period of time beginning about 455 AD and extended for about 1000 years.
