(Scenic Wonders‚ 2014) The peak of Half Dome is over 4‚700 feet above the valley floor. The Granite rock that makes up Half Dome was formed over 93 million years ago during the Cretaceous period. The granite was formed from magma that solidified underground. Through erosion of the sediment on top of the rock‚ the granite of Half Dome was exposed. Erosion is defined as “the process in which wind‚ water‚ or glaciers remove weathered

extinction events. In the Carboniferous‚ rainforest collapse led to a great loss of plant and animal life. The Permian–Triassic extinction event‚ 251 million years ago‚ was the worst; vertebrate recovery took 30 million years.The most recent‚ the Cretaceous–Tertiary extinction event‚ occurred 65 million years ago‚ and has often attracted more attention than others because it resulted in the extinction of the nonavian dinosaurs. The period since the emergence of humans has displayed an ongoing biodiversity

Stratigraphy of the Jurassic Upper Jurassic The Upper Jurassic is described in the record by a low-relief transition from shallow-water into basinal facies (Winker & Buffer‚ 1988). Further‚ there is little to no evidence of seismic expression It has been documented that there are facies tracts from past basinal marine all the way to shallow marine as well as nonmarine in this area. In addition to this‚ the oldest confirmed Mesozoic sediments classified as marine in the province of the basin

Long Chan Topic: How are cockroaches adapted to survive? Cockroaches are more powerful insects‚ which live in a wide range of environment almost around the world‚ form the east to west and form the north to south‚ and human can see them in different districts around the world. The Cockroaches have about 30 species out of 4500 total are associated with human habitats and about four species are well known as pests. However‚ why they can succeed in the world? Follow that I will do some researches

How do you think the principle of uniformitarianism accounts for occasional catastrophic events such as meteorite impacts‚ huge volcanic eruptions‚ or great earthquakes? Because uniformitarianism shows us that if our earths plates are moving today‚ they were moving in the past. This moving of the plates causing things such as earthquakes. In what ways do geologic processes affect your daily life? Geology is the study of earth‚ which is where we live. Understanding geology and how it works‚ helps

The volcanic islands known as the Galapagos Islands are found 600 miles off the coast of Ecuador and are home to the Galapagos penguins‚ the only species of penguins in the world to live north of the equator. Despite the common belief that penguins only live in the Arctic‚ the Galapagos Islands have temperatures that vary from 70-90º Fahrenheit over the course of the year. The distribution of these birds in their environment correlates with the “Cromwell Current‚ which provides cold nutrient-rich

Adelobasileus shows an intermediate condition between cynodonts and mammals and its status as mammals has been doubted (Lucas and Luo 1993). The recent discovery of Hydrocodium wui provides evidence for the earliest known mammal in 195 million year old Cretaceous Chinese sediments‚ suggesting that the mammals evolved 45 million year earlier than previously recognized (Lou et al. 2001). The small body size of Hydracotherium also reveals that there was more evolutionary diversity among early mammals than had
