- The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere. The layer below the rigid lithosphere is a zone of asphalt-like consistancy called the Asthenosphere. The asthenosphere is the part of the mantle that flows and moves the plates of the Earth.

The Earth's Layers Lesson #1 Basaltic rocks of the ocean plates are much denser and heavier than the granitic rock of the continental plates. Because of this the continents ride on the denser oceanic plates. The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere. The layer below the rigid lithosphere is a zone of asphalt-like consistancy called the Asthenosphere.

High School Earth Science/Theory of Plate Tectonics Two Oceanic Plates-When two oceanic plates collide, one may be pushed under the other and magma from the mantle rises, forming volcanoes in the vicinity. Two Continental Plates-When two continental plates collide, mountain ranges are created as the colliding crust is compressed and pushed upwards.

There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. Magma from the mantle solidifies into basalt, a dark, dense rock that underlies the ocean floor. Thus at divergent boundaries, oceanic crust, made of basalt, is created. When two plates come together, it is known as a convergent boundary. The impact of the two colliding plates buckles the edge of one or both plates up into a rugged mountain range, and sometimes bends the other down into a deep seafloor trench.

What is a subduction zone and what types of plate boundaries have subduction zones? The two plates are said to converge. One plate may be more dense than the other, and with the two plates pushing against each other, the plate that is more dense will slide under the other plate. The plate sliding under is said to subduct the other plate, and this creates what is called a subduction zone.Not all convergent plate boundaries have subduction zones, but all subduction zones are formed at convergent plate boundaries.he two plates are said to converge. One plate may be more dense than the other, and with the two plates pushing against each other, the plate that is more dense will slide under the other plate.

How Did Krakatoa Form? Quick Answer. Krakatoa was a stratovolcano, and it formed by ejecting matter in a manner typical of other stratovolcanoes. According to Oregon State University, stratovolcanoes are sometimes referred to as cinder cones in reference to the manner in which they are built up. Continue Reading.

Plate Boundaries Oceanic crust is more dense than continental crust. When two plates carrying oceanic crust meet at a trench, the plate that is less dense dives under the other plate and returns to the mantle. This is the process of subduction. When a plate carrying oceanic crust collides with a

What Is a Subduction Zone? A subduction zone is the biggest crash scene on Earth. These boundaries mark the collision between two of the planet's tectonic plates. The plates are pieces of crust that slowly move across the planet's surface over millions of years. Where two tectonic plates meet at a subduction zone, one bends and slides underneath the other, curving down into the mantle. (The mantle is the hotter layer under the crust.). Tectonic plates can transport both continental crust and oceanic crust, or they may be made of only one kind of crust. Oceanic crust is denser than continental crust. At a subduction zone, the oceanic crust usually sinks into the mantle beneath lighter continental crust.

The Biggest Blast from the Past (Exploding Volcano Photo Blog) A new island volcano, named Anak Krakatau, or Child of Krakatoa, rose above the waterline a few days later. The eruptions were initially of pumice and ash, and that island and the two islands that followed were quickly eroded away by the sea. Eventually a fourth island named Anak Krakatau broke water in August 1930 and produced lava flows faster than the waves could erode them.

Plate tectonics The location where two plates meet is called a plate boundary. Plate boundaries are commonly associated with geological events such as earthquakes and the creation of topographic features such as mountains, volcanoes, mid-ocean ridges, and oceanic trenches.he lithosphere, which is the rigid outermost shell of a planet (the crust and upper mantle), is broken up into tectonic plates. The Earth's lithosphere is composed of seven or eight major plates (depending on how they are defined) and many minor plates.

Krakatoa Volcano: Facts About 1883 Eruption It is estimated that more than 36,000 people died. Many died as a result of thermal injury from the blasts and many more were victims of the tsunamis that followed the collapse of the volcano into the caldera below sea level. The island of Krakatau (Krakatoa) is in the Sunda Strait between Java and Sumatra.It is part of the Indonesian Island Arc. Volcanic activity is due to subduction of the Indo-Australian tectonic plate as it moves northward towards mainland Asia. The island is about 3 miles wide and 5.5 miles long (9 by 5 kilometers).rakatau (Krakatoa) in the Sunda Strait between Java and Sumatra. Credit: CIA World Factbook. View full size image. At 12:53 p.m. on Sunday the 26th, the initial blast of the eruption sent a cloud of gas and debris an estimated 15 miles (24 km) into the air above Perboewatan.

What is a Monosyllable? Like sparks in the night, they light the way for the eyes of those who read. They are the grace notes of prose. You know what they say the way you know a day is bright and fair--at first sight. And you find, as you read, that you like the way they say it. Small words are gay.

High School Earth Science/Theory of Plate Tectonics Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other. The movement of the plates, and the activity inside the Earth, is called plate tectonics. Plate tectonics cause earthquakes and volcanoes. The point where two plates meet is called a plate boundary. Earthquakes and volcanoes are most likely to occur either on or near plate boundaries. The map shows the world's tectonic plates and the distribution of earthquakes and volcanoes. The Earth's plates move in different directions.

Tectonics Crust is consumed in subduction zones. When two plate move together, one of them must slide under the other one. This is called subduction. When an oceanic plate and a continental plate meet, the denser oceanic plate subducts under the less dense continental plate. The subducting plate slips down into the mantle where it is heated, melts and is recycled. Thus spreading centers and subduction zones act like a conveyor belt, manufacturing crust at one end and consuming it at the other. The deepest parts of the ocean occur in trenches along subduction zones.

Emperor The imperial title continued in China until the Qing Dynasty was overthrown in 1912. The title was briefly revived from 12 December 1915 to 22 March 1916 by President Yuan Shikai and again in early July 1917 when General Zhang Xun attempted to restore last Qing emperor Puyi to the throne.n general, an emperor would have one empress (Huanghou, 皇后) at one time, although posthumous entitlement to empress for a concubine was not uncommon. The earliest known usage of huanghou was in the Han Dynasty. The emperor would generally select the empress from his concubines.
