Answer:
1- Option (D)
2- FALSE
Explanation:
The seafloor spreading takes place because of the divergent plate motion. Alfred Wegener observed this motion of the seafloor and the continents but was not able to explain the main mechanism behind this until the new theory came into the picture. The divergent motion of seafloor and the motion of the continents were explained by the universally accepted theory known as the Plate tectonic theory. This theory was able to explain the mechanism behind this plate motion.
The study of the seafloor spreading provided some pieces of evidence that supported the continental drift theory. They gave a basic idea about how the oceanic plate gets subducted (consumed) at the convergent plate motion that undergoes partial melting at greater depth. As a result of which the magma rises up to the surface on the overriding plates.
The crust represents the outermost layer of the earth. They are of 2 types, namely the oceanic and the continental crust. These crusts when slide past one another in a transform plate boundary, it is neither created nor destroyed. It remains conserved.
Thus, the correct answers are given above and the second statement is false.
This is an example of a closed system

Hello, welcome to Brainly!
Earthquakes are typically prompted when rock underground suddenly breaks alongside a fault. This sudden launch of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing in opposition to each other, they stick a little. They don't simply slide smoothly; the rocks seize on each other. The rocks are nevertheless pushing towards each other, however now not moving. After a while, the rocks spoil because of all the stress that is built up. When the rocks break, the earthquake occurs. During the earthquake and afterward, the plates or blocks of rock start moving, and they proceed to go till they get caught again. The spot underground the place the rock breaks is known as the focal point of the earthquake. The area proper above the center of attention (on pinnacle of the ground) is called the epicenter of the earthquake.
Answer:
y=4x-16
Explanation:
The general form of the equation of a line is: y=mx+x, where m is the gradient and c is the y-intercept.
Given points (-3,-3) and (-1,5)
We are to find the equation of the line parallel to the given line with an x-intercept of 4.
First, we determine the value of the gradient of the line.
Gradient,
Two lines are parallel if their gradients 
are equal.
The gradient of the line parallel to the given line 
Since the x-intercept of the new line is 4, a point on the new line, 
Substituting into the equation of a line: , 
we have:
Therefore, the equation of the line is: y=4x-16
