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.
I am almost positive that the answer is A. freezing
I got B but some of the numbers are blurry
Answer:
At some point in the not-so-distant future, whites will become the racial minority in the United States. Why is that so terrifying to some of us — why must we see it as a win-lose? Black culture, tempered in the fires of slavery and Jim Crow and by myriad forms of rural and urban, Southern and Northern, discrimination, has deeply enriched our national life. In the face of repeated exclusion and abuse, Blacks have chosen to keep faith with the core promises of our Constitution. Their leaders, like the late John Lewis, are therefore in a position to make what Lewis called “good trouble” — holding our collective feet ever closer to the fire of our professed principles. Ms. Gorman will be of legal age to run for president in 2033. If I’m still around, I would joyfully vote to put myself in her capable hands.
Explanation:
The force that attracts any two pieces of matter in the universe is called the gravitational force.
<h3>What is gravitational force?</h3>
Corresponds to the mutual interaction between two bodies in space, being attractive and not repulsive, allowing the translational movement of the earth and the movement of planets in orbit around the sun.
Therefore, the gravitational force was proposed by Isaac Newton, in an episode in which the physicist observed an apple falling from a tree, identifying the way in which gravity causes objects to be attracted to the center of the earth.
