What does freezing and thawing do to rocks?
Regional SpecificsFreezing and thawing of water in the joints and cracks of rocks creates smaller fragments with more surface area, making rocks more susceptible to chemical and biological weathering. What happens to a rock when it freezes? Scientists have observed a process called freeze-thaw. That process occurs when the water inside of rocks freezes and expands.

What is the geological history of Hawaii?
Regional SpecificsA hotspot beneath the Pacific Plate created Hawaii’s volcanic islands. As this hotspot has remained stationary over the last 40 million years, the plate above has drifted west-northwest at a rate of three and a half inches per year. Over time, the hotspot resulted in 82 volcanoes emerging to form the Hawaiian Ridge. When was

What technology is used in marine biology?
Regional SpecificsMarine biologists use computers in their research and writing. They use biostatistical programs to draw conclusions about marine populations. They use microcomputer programs for word-processing, entering data on a spreadsheet, putting together presentations and searching the Internet for research publications. What technology do marine biologists use? They use equipment including boats, scuba gear, nets, traps,

How subduction can cause volcanism?
Regional SpecificsAt a subduction zone an oceanic crust is pushed under the continental crust. As the oceanic crust is pushed under the continental crust it is subjected to heat and pressure. The heat and pressure causes the crust to melt and become magma. … When the magma reaches the surface it creates a volcano. How does

Which continents were together during the Neogene period?
Regional SpecificsTerrestrial Life During the Neogene Period During the later Neogene, the interconnections between Eurasia, Africa, and North and South America set the stage for a confusing network of species interchanges, resulting (for example) in the near extinction of South America’s Australia-like marsupial megafauna. What were the continents during the Neogene period? The continents in the

What is the difference between Terrane and terrain?
Regional SpecificsWhat is the difference between terrane and terrain? “Terrane” describes a crustal fragment consisting of a distinct and recognizable series of rock formations that has been transported by plate tectonic processes, whereas “terrain” describes the shape of the surface topography. How is terrane different from terrain? is that terrane is (geology) a block of the
