Answer:
Sea-floor spreading occurs in the oceanic ridges. In there, volcanic activity, together with the gradual movement of the bottom, form new oceanic crust. This allows a better understanding of the continental drift explained by the theory of plate tectonics.
The greatest evidence for Sea-floor spreading is the oceanic trenches, the oceanic ridges, the magma protruding to the surface and the new seafloor.
In previous theories, continents were assumed to be transported across the sea. Harry Hess, in the 1960s, proposed the idea that the seabed itself moves as it expands from a central point. The theory is now accepted, and the phenomenon is thought to be caused by convection currents in the upper layer of the mantle.
Answer:
Tech B
Explanation:
There is a revolution of changes occur since the beginning of vehicle creation. Many technology came into existence and proposed us the best design, features and model. But as a machine, several fatigue or wear and tear can happen to this hence a proper maintenance is required in order for smooth running of your vehicle.
Many manufacturers have booklet that mention the proper maintenance interval for better running of your vehicle. As daily environment is changing, the maintenance requirements of a vehicle is also changing. New technology is bringing new features hence their maintenance rate as well as requirement also needs to be upgraded.
Here's a explanation!
Let's solve your equation step-by-step.
Step 1: Multiply both sides by x.
(Divide both sides by 4).
Take the root.
