Answer:
D
Explanation:
D layer is the last layer of the soil that is present at the bottom of other layers having the oldest layers. The bottom layer of soil is formed first and when we go up the age of soil layers decreases because it is formed after the parent soil. The fossil that is present at the bottom layer is considered as oldest fossil as compared to those fossils that are present in the above layers of that soil.
The North Sea has very important natural resources such as oil and natural gas. Oil is a mixture of organic compounds, mainly hydrocarbons insoluble in water, it is also known as crude oil or simply crude and gas natural which is an important source of fossil energy released by its combustion.
I have no idea, but I wouldn't use Wikipedia.. The "facts" on there aren't always true. That's why we aren't allowed to use it in my high school.
Answer:
As the wind passes over the surface of the oceans, a portion of the winds kinetic energy is transferred to the water below, generating waves.The kinetic energy of the wave turns a turbine attached to a generator, which produces electricity.The wave energy is absorbed by radiating a wave with destructive interference to the incoming waves. Buoys use the rise and fall of swells to generate electricity in various ways including directly via linear generators, or via generators driven by mechanical linear-to-rotary converters or hydraulic pumps.
Answer:
Paleozoic
Explanation:
The Paleozoic Era is a geologic era that lasted from 541 to 251.902 million years ago. This is divided into six geologic periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. The swamps that were turned into coal over time grew during the Carboniferous period, which expands from 358.9 million years ago to 298.9 million years ago. The period is well-known because many coal beds were formed during that time period. During the Carboniferous, terrestrial animals were well-established. It ended with a minor extinction event known as the Carboniferous rainforest collapse.
