A mushroom rock, also called rock pedestal, or a pedestal rock, is a naturally occurring rock whose shape, as its name implies, resembles a mushroom. The rocks are deformed in a number of different ways: by erosion and weathering, glacial action, or from a sudden disturbance.Pedestal rocks generally form in sandstone/shale terrains, with differential erosion producing a sandstone cap on a shale base.
Answer:
- the distribution of earthquakes
- certain fossil distributions
- the distribution of volcanoes
- the location of mountain chains
Explanation:
The plate tectonics are crucial for the processes that happen on the surface or near it on our planet, as well as the physical features of it. The movement of the tectonic plates causes lot of stress when they interact, and from that stress, the crust deep inside cracks and adjusts, which releases a lot of energy and causes earthquakes. Also, on the plate boundaries, because the crust is cracking and is not as tough, the magma from the mantle manages to rise up, and as it reaches the surface it lifts up the land in a cone shape, creating volcanoes, be it as island or continental arcs. When continental tectonic plates collide, they don't subduct, but push against each other, and that enormous pressure lifts up the area around the boundary, gradually giving rise to mountain chains. The fossils are n interesting example as well, as they are one of the best clues about the movement of the tectonic plates. There are lot of fossils that are identical, from the same species, but found on different continents that are not connected in the present, indicating that in the past the continents had different positions and were connected.
The baby-boom generation is a generation that has had much different lifestyle than the previous generation, or rather the generation of their parents. The rights of the men and women have become equal, as well as the earnings. The marriage has been delayed for later stages of life, also having less children, and relatively high divorce rates.
On the long run, this generation will have a negative demographic impact on the United States. The reason for that is that the birthrates of this generation have dropped significantly, and it is also representing a large portion of the population, so as they age they will contribute to aging population.
An aging population can have serious economic and social impact, as the percentage of people that take money from the pension funds will increase significantly relative to the people that work. Also, as the baby-boomers age, the healthcare will be overrun by them, as deep age and diseases often goes hand to hand, so the expenses for the healthcare will be enormous.
Answer: As hyperopia results from the visual image being focused behind the retina, it has two main causes: Low converging power of eye lens because of weak action of ciliary muscles. Abnormal shape of the cornea.
