Chapter One The theory of plate tectonics explains how forces within the planet create landforms. This theory views Earth’s crust as divided into more than a dozen‚ rigid‚ slow-moving plates. Some plates are as large as a quarter of the planet‚ but others are only a few hundred miles across. The plates slowly move across the upper mantle‚ usually less than an inch per year. Scientists use the theory of plate tectonics to explain the long history of Earth’s surface. They believe that about a few

EOSC 114: Volcanoes Notes from Web Notes Lesson 1: Why Do Volcanoes Have Different Characteristics? A. Formation of Lava Magma is formed by melting preexisting rock in Earth’s interior For magma to rise through crust it must be: (1)less dense than the crust (2) runny enough to flow (3) hot enough to stay liquid Magma that cools to form solid rock = lava B. Composition of Magma/Lava Magma is composed of various proportions of: Oxygen‚ Silicon‚ Aluminum‚ Iron‚ Calcium and Potassium Mineral –

Volunteer for World Parnership Golf This article is mainly about the how we volunteered for the World Partnership Golf and what we gained from this event. We made a good decision after analyzing pros and cons of different options with a satisfactory outcome. To help people in poverty‚ this project gave us an opportunity to dedicate ourselves to doing something good to the society. In the end‚ I fulfilled my duty with my heart and soul with a terrific take-away lesson for team work. World Partnership

Before you undertake this assignment‚ please read carefully the handout that gives an overview of EvolutionLab. This will make it much easier for you to understand the assignment and complete it correctly. 1. There are many ecological and biological factors that affect evolution. In EvolutionLab‚ two populations of finches are tracked over the course of 300 years on two different islands to see how changing the traits of the birds and their environment affect their long term viability as a sustainable

Convergent Webbing * In convergent semantic webbing‚ you begin with a series of concepts or ideas and ask your students to tell you what they know about those concepts and how they think their text is going to deal with them. Divergent Mapping * In divergent mapping‚ students list sub-topics for a main concept or idea‚ and put those sub-topics into categories‚ taking what

Of all terrestrial planets we know of‚ Mercury’s geology is the most unknown. This is because of its closeness to the sun‚ making human observation via spacecraft and from Earth very difficult. There are many craters on Mercury that are made from a particular impact. There is also balsatic rock and plains which are made in the event of a massive volcanic eruption. There are also vents‚ made when a magma chamber collapses. Mercury’s density has produced a solid iron core that accounts for 60% of its

Objective The objective of this experiment was to find the focal length of two converging lenses separately and also to find the focal length of combination of two converging lenses. Another objective was to study the image formed by a converging lens plus diverging lens. Background This experiment focused on a simple lens system. A simple lens is a piece of glassware that is spherical on one side and flat on another side‚ or spherical on both sides. There are two different types of lenses

the surface. On Earth‚ volcanoes are generally found where tectonic plates are diverging or converging. Amid-oceanic ridge‚ for example the Mid-Atlantic Ridge‚ has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes 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

What are the three main types of plate tectonic boundaries and any subdivisions of each? What are the plate motions relative to each other? What are the stresses associated with each? Are there any features associated with these boundaries (mid-ocean ridge‚ trench‚ subduction zone‚ rift‚ volcanoes)? Convergent- Plates move
