how does fossil evidence of forests and freshwater organisms in Antarctica show that the climate there was warmer in the past
noname [10]
The fossil record of Antarctica shows the presence of tropical plants, such as one particular species related to the present day breadfruit. Most plants cannot survive in prolonged temperatures of less than 6 degrees Celsius. Antarctica is freezing all year round and could only have supported tropical and sub tropical plants if it was once much closer to the equator.
The presence of fresh water species also suggest that the continent was closer to the equator. Antarctica is frozen solid with a thick ice sheet.....rivers would be frozen solid all year round or would be limited to water movement under glaciers that melt as a result of pressure and friction. This environment is not suitable to support large fresh water organisms.

Compare the processes by which a car and a human use "fuel" to perform work. What are the similarities?
Alenkinab [10]

A car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.

<h3>What is energy?</h3>

Energy is the capacity of doing work. In physics, there exist different types of energy; among which are follows:

  • Kinetic energy: Kinetic energy can simply be defined as that energy a body posses due to its motion
  • Potential energy: , On the other hand, potential energy is the energy a body has due to its relative position.

Other forms of energy include:

  • Solar energy
  • Nuclear energy
  • Mechanical energy

So therefore, a car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.

Therefore, kinetic energy is the energy which allows a car to be fueled before it can set in motion .
