Molten magma from the mantle rises at the top oceanic ridge, cools and solidifies, continually forming a crustal plate. Hundreds to thousands of miles from the ridge the plate moves downward into the mantle at the contact with another plate and melts. The continuous process resembling a large "conveyor belt" moves the crustal plate a few centimeters each year.

∙ 12y agoCrustal plates have moved over time on the mantel underneath the earths crust . They move in the direction north and move to create volcano's.

What caused 2011 Japanese tsunami hit?
The plates over time moved ontop of each other and that caused the earthquake and the earthquake caysed the tsuanarmi! hope i helped xxx
What are tectionic plates?
the plates move over time . they move 10cm (4in) a year however over millions of years they move thousands of kilometers . this is plates tections
What do convection currents do over time?
They move tectonic plates
What type of plate boundary formed the Mid-Atlantic Ridge in the Atlantic Ocean?
A constructive plate margin (which is where 2 plates move away from each other). Over a long period of time, magma rised to fill the gap where two plates moved, forming this mid Atlantic ridge.
Does fossil evidence provide support for the idea that continents have moved over time?
no
Discuss evidence that suggests crustal plates move over time?
1. Earthquakes 2. Radioactivity from the plates.
When is the last time Hawaiian hot spot moved?
Actually as far as we know none of the hot spots has ever moved. The plates move over them.
How did the movement of crustal plates cause mountains and earthquakes to form on earth's surface?
When the tectonic plates push together over a period of time, sometimes they jolt, like recently with Japan. However, most were far more violent than that, infact the Himalaya's are basically two plates that hit each other and went straight up.
How did the Ring of Fire form?
The Ring of Fire is formed by the movement of Earth's crustal plates which are causing the Pacific Ocean to be subducted under less dense plates. This subduction results in underwater and continental volcanism, resulting in a line of eruptions which appear around its boundaries with other plates.

Is Alfred Wegener's hypothesis true about continental drift?
Yes and no. His hypothesis about how the plates were moved eventually was proven wrong, although his hypothesis that the plates had shifted in position over time was proven. The physical evidence in support of continental drift (now referred to as the theory of plate tectonics) began to be considered overwhelming back in the 1960s, with the discovery of the mid-ocean ridges and the accompanying paleomagnetic striping along the sea floor which has recorded magnetic reversals in newly formed crustal rock. More recently, we have measured the rates of motion of each of the continental plates using GPS satellite technology. The fact the plates drift is now indisputable.
What is the theory that continents have moved slowly over time to their current locations?
The theory that continents have moved slowly over time to their current locations is called continental drift. This theory was proposed by Alfred Wegener in the early 20th century and later developed into the theory of plate tectonics, which explains the movement of Earth's lithosphere through the interaction of tectonic plates.

How has islands change over time?
islands change over time by many movements by the tectonic plates and activity

How do foothills change over time?
When earths plates collide together
