Answer:
its A simple technique to help refine your sales and marketing message to ensure it hits the centre of the target for your core customer every time.
B. It grows as nuclear fusion in its core produces more matter.
Convergent-compressive
Divergent-tensional
Transform-shear
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, lava spews from long fissures and geysers spurt superheated water. Frequent earthquakes strike along the rift. Beneath the rift, magma—molten rock—rises from the mantle. It oozes up into the gap and hardens into solid rock, forming new crust on the torn edges of the plates. Magma from the mantle solidifies into basalt, a dark, dense rock that underlies the ocean floor. Thus at divergent boundaries, oceanic crust, made of basalt, is created.
Kelvin lowered his prediction to 20 million years based on fresh data on the granite melting point.
<h3>What did Lord Kelvin believe about the Earth?</h3>
The Earth, according to Kelvin's theory, solidified from a molten state in which it was first all at a high temperature that was then maintained at a constant surface temperature.
<h3>How did Lord Kelvin calculate the Earth's age?</h3>
Using temperature gradients, Kelvin computed the age of the Earth and calculated that it was approximately 100 million years old. He was unaware that the Earth's mantle was convecting, which rendered his prediction inaccurate.
<h3>What was Lord Kelvin's theory?</h3>
According to Kelvin's law, heat from a high-temperature energy source cannot completely be transformed into "work." A portion of the heat will be transformed into poor energy and "lost" in the process. This demonstrated that a heat engine cannot be completely efficient.
