How did the discovery about seafloor spreading modify the theory of Continental drift?
Seafloor spreading explained WHY and how Continental Drift occurs. How can lands be 'moving' without a catastrophic or even noticeable change--- seafloor spreading accounts for these small changes. It identifies where the actual changes take place (even if we cannot identify the exact spots where spreading occurs). We can better estimate how much the "spreading" equates to observable/measurable changes of continents, specifically how fast (slowly) continents are moving closer or further apart. Seafloor spreading explains other phenomena, too, like the expulsion of methane gas pockets at the ocean floor which are suspected to interfere with flotation of ships and possibly the downing of airplanes that pass over where methane is released when methane gas disrupts the air above the water. Seafloor spreading also gives clues as to how mountains and valleys form underwater and on land.
What is the fastest wind found in a Hurricane?
The fastest wind speed ever recorded in a hurricane was about 190 mph (305 km/h) in Hurricane Patricia in 2015.
What design challenges do scientists face in trying to land a spacecraft on a comet?
the speed of a comet and the rotation is far too fast for a spacecraft to land
What cause sea floor spearding and continetal drift?
Sea floor spreading is caused by the upwelling of magma at mid-ocean ridges, creating new crust that pushes the existing plates apart. Continental drift is driven by the movement of tectonic plates on the Earth's surface, as they float on the semi-fluid asthenosphere layer below. The slow movement of these plates over millions of years results in the shifting of continents across the globe.
What do scientists use to calculate how fast the plates move?
Scientists use GPS (Global Positioning System) technology to calculate how fast tectonic plates move. By tracking the movement of GPS stations placed on different plates over time, researchers can measure the rate of plate movement with high accuracy.
How fast does continental drift happen?
Continental drift occurs at a rate of about 2-5 centimeters per year, which is approximately the same speed at which fingernails grow. This movement is due to the slow spreading of tectonic plates beneath the Earth's surface. Over millions of years, this movement can lead to significant changes in the positions of continents.
Is tectonic plates a slow or fast change?
Tectonic plates move very slowly, but earthquakes are quite sudden. So, there are elements of slow change and fast change. Continental drift is slow.

Why is Lucas Black not in Fast Five?
The events of Tokyo Drift happened after the events of Fast Five. Tokyo Drift is really not a sequel to 2 Fast 2 Furious. In fact, you could watch every movie in the series except for Tokyo Drift and not miss anything.
