1. The science of biogeography is the description of distribution of life and the explanation of this description. The description is based on both time and space. This describes how things look and why they are there. It also looks to answer the question – are these features the same over time? Biogeography arose with the theory that life on earth is a non-random distribution. This is the most important observation leading to the field of biogeography. The study of biogeography includes many other

caused by convergent tectonic plates coming together. By contrast‚ volcanoes are not usually created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching and thinning of the Earth’s crust in the interiors of plates‚ e.g.‚ in the East African Rift‚ the Wells Gray-Clearwater volcanic field and the Rio Grande Rift in North America. This type of volcanism falls under the umbrella of "Plate hypothesis" volcanism.[1] Volcanism away from plate boundaries has also

1. A ________ is a well-tested and widely accepted view that best explains certain scientific observations. Answer | | hypothesis | | | generalization | | | law | | | theory | 2 points Question 2 1. What are the basic differences between the disciplines of physical and historical geology? Answer | | physical geology is the study of fossils and sequences of rock strata; historical geology is the study of how rocks and minerals were used in the past |

depicting the locations which are prone to both. Volcanism is associated with two of the plate boundary types: divergent and convergent margins‚ so activity is usually found along oceanic ridges where plates are moving apart‚ near rift valleys‚ on subduction zones where the most violent activity takes place and over hot spots which have given rise to the Hawaiian islands. Magma is generated at most plate boundaries‚ and this magma rises to the surface to form volcanoes. The mobility of crust also causes

Tsunamis‚ the ins and outs What is a tsunami? Tsunamis (Japanese for “Harbor Wave”) are series of waves that are characterized by their massive wavelengths‚ often about 120 miles long‚ whereas a normal wave has one of about 333 feet‚ and destruction that they bring when they hit land. They are often called tidal waves‚ but incorrectly so. They have virtually nothing to do with the tides. Tsunamis can range from a few feet in height to over a hundred feet

Name _______________________ Period _________ Chapter 22: Descent with Modification: A Darwinian View of Life As you study this chapter‚ read several paragraphs at a time to catch the flow of ideas and understand the reasoning that is being described. In some places‚ the text describes a narrative or story of events that led to Darwin’s theory of evolution. Therefore‚ first read the narrative to absorb the big picture and then return to answer the few questions that accompany this material

grow * Convergent Plate Boundary: occurs when internal forces push two plates together. Oceanic plates collide with continental plates‚ making the continental plate ride up over the denser oceanic plate and pushes it down into the mantle (subduction) * Subduction zone: the area where the collision and subduction takes place * Mountains are formed by two continental plates colliding and pushing up. Ex- Himalayas being formed by China and India * Divergent Plate Boundary: Oceanic plates
