<span>In simple terms, heavier plates get melted
in Mantle, become lighter in form of lava and create new plates. As we
have a re-cycle or the convection currents, there are cycles in
lithosphere.
There is continuous push and pull happening on and
below the Earth. When a plate is subducting on one end, there has to be
some reaction on the other end, right?
Ridge is developed on the
other side, where the same material which has been melted on the
subduction side helps to fill the gap at ridge side. Since the material
is just transfered from heavy to light, and reused in that cell, it is
called a cycle.

Answer:
The influenza H1N1 virus is transmitted through saliva droplets and mucus from sick people, who by sneezing or coughing without covering their mouth and nose adequately, leave the virus in the air or on their hands, infecting then the objects they touch. As a rare occurrence, a person can become infected with the flu by touching a surface or object contaminated with the influenza virus and then touching the mouth, nose, or eyes.
Pigs sometimes transmit influenza H1N1 virus to people, primarily pig farmers and veterinarians.
Natural selection is basically a way for nature to choose what works and what doesn't work. For example, if an animal was born with webs to swim, but most of its food source can be gotten on land, then the animal will die off until it evolves to go on land. That is how evolution works with natural selection. In the past long ago, millions of years back, animals in the water needed oxygen to breath, but the water started to lose it. The land had air, and then the fish slowly grew legs, and their gills would evolve to lungs. Eventually they would be able to roam the land. Because there was so much oxygen with all of the shrubs, trees, and plants, that allowed the bodies of animals to grow big.
