Answer:
Seafloor spreading results from intense activity in the upper mantle which cracks the crust and pushes it away.
Explanation:
Seafloor spreading is a process that was first noticed by Alfred Wegener and was used by him in his theory of plate tectonics. There are three types of plate boundaries; convergent boundary, transform boundary, and divergent boundary. The last one is the one where seafloor spreading occurs.
The convection currents in the mantle are the process that breaks up the crust and move the tectonic plates, and when there is higher activity than usual at some place it results in break up the crust of an already existing tectonic plate. Basically, magma rises at a higher rate and pushes through the crust, in this case, the oceanic crust, and it manages to gradually break through it and come out on the seafloor. By doing so, the magma and the pressure from below are pushing the two now divided parts of the plate. As the space between the two different parts becomes larger and large the density of the crust becomes smaller and smaller so more and more magma rises through. The magma quickly solidifies on the ocean floor and piles up, thus creating an underwater mountain range known as a mid-ocean ridge.
Answer:
Magnitude
Explanation:
Earthquakes are typically measured in units of magnitude. The news usually use the most popular measurement scale called the Richter Scale which rates an earthquake by the size of its seismic waves on a scale from 1 to 10.
Ex. Mexico had a 7.1 magnitude earthquake

Hello!</h2>
The answer is 63,019
<h2>Why?</h2>
According to the Department of Highway Safety and Motor Vehicles annual report, 63,019 DUI violations/citations were recorded from 2009-2010 fiscal year, resulting in 36,872 convictions.
Driving Under the Influence (DUI) are the most common traffic violations recorded around the country. DUI is commonly known as drunk driving and it refers to drive while blood alcohol is elevated, meaning that the driver is not able to drive safely.
Have a nice day!
