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

It is the most accessible type of shape.

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

CARIBBEAN STUDIES UNIT ONE TERRITORIAL UNITS IN THE CARIBBEAN • WHAT IS THE CARIBBEAN Greenwood and Hamber (2003) defines the Caribbean as‚ “all the countries in and around the Caribbean sea that lie within an area that stretches from Grand Bahama Island in the north to Curacao in the south and from French Guiana in the east to Belize in the West. The Wikipedia Encyclopedia defines the Caribbean as‚ “a region of the Americas consisting of the Caribbean Sea‚ its islands (most of which enclose

this volcano is. The Volcanic ash that erupted from the mouth of the stratovolcano condensed into pebbles of ash‚ and chunks of coal from the volcano. At that time the lava with high viscosity had not erupted yet. The VEI of the volcano on the convergent boundary between the African and Eurasian plate is 7 on the scale. ~Armeet Chhina People in Pompeii had no idea what was going on because there was no word in latin for volcano and they thought that Mt. Vesuvius was just a mountain and they didn’t

Chapter 1 1.1 Earth Science & the Earth System -Earth science is the study of Earth and the processes that shape it -The earth system is composed of four principal components: atmosphere (air‚ weather)‚ hydrosphere (water‚ ice)‚ biosphere (plants‚ animals)‚ and geosphere (land‚ rocks). - Earth science can be broadly defined as the investigation of interactions among the four parts of the earth system. - The second largest earthquake ever recorded buckled the seafloor west of Sumatra‚ Indonesia
