Henry David Thoreau Introduction • • • Earth’s lithosphere is divided into mobile plates. Plate tectonics describes the distribution and motion of the plates. The theory

The Juan De Fuca tectonic plate is found on the west coast of North America. It is next to the North American plate‚ and according to America’s Tectonics‚ the Juan de Fuca plate is getting subducted under it. This plate is made of oceanic crust‚ but it is also basaltic in some areas. It was named after the pilot and sailor‚ Juan de Fuca‚ an explorer from Europe in the 1600s. The Juan de Fuca plate has a divergent boundary in the Juan de Fuca ridge. New material is made by the Juan de Fuca ridge

Plate Tectonics Press Release GLG/101 July-27‚ 2014 Kathy Howard Plate Tectonics Press Release How can the families of Los Angeles be prepared for an earthquake? This is a very important question that haunts us every day‚ because we don’t always know when they are coming and how bad they will be. I am Donte Lindsey and I am the director of Earth Preparedness of Los Angeles. With any type of danger the first thing you need to be prepared with is knowledge. Today we will discuss the hazards

Planarians A planarian is a small free-living flatworm. These flat worms are usually found under rocks in fresh water. They are part of the phylum Platyhelminthes and in the class Turbellaria. Planarians are usually zoophagous‚ they feed on small living invertebrates and decaying organisms found in their community. Some planarians could eat segmented worms‚ leeches‚ snails‚ and other small herbivores. Planarians may also be organisms that gain their food energy with the help of decomposing

Plate tectonics provide the perfect clues to where and what seismic hazard will occur? Discuss. It is at the boundaries of the planet’s tectonic plates that most of the world’s major landforms occur and where earthquakes‚ volcanic and mountain building zones are located. The surface of the planet is made up of seven large and several smaller rigid tectonic plates which float on the semi-molton asthenosphere; the movement of these plates is influenced by the convection cells under the lithosphere

Adapted from an activity by Laurel Goodell February 2013 Introduction to Plate Tectonics via Google Earth (24 pts) B. Topographic Patterns Uncheck all of the layers and focus on topographic features of the earth. Topography of the earth ABOVE sea level Questions Answers 1. Are mountains randomly distributed on the continents‚ or do they tend to occur in particular patterns (clusters‚ linear chains‚ arcs‚ etc.)? Some appear in lines and others in arcs 1pt 2. Find Mt.

Plate Tectonics‚ Earthquakes‚ and Volcanoes Renee Kuraly 1. There are 13 tectonic plates. (several smaller ones) 2. Evidence for continental drift includes: coastline fit‚ alignment of mountain ranges‚ similar rock sequences‚ fossils‚ modern fauna‚ and ancient climates. 3. We know plate boundaries exist because their defined by earthquake data and the depths of earthquakes show what type of boundary they are. 4. Divergent Boundary- places where plates are moving apart. Convergent Boundary-

OSMOSIS IN POTATO TISSUES Vanessa Tsao‚ Lovette To‚ Wang Yeyun‚ Zhang Shenjia‚ Alicia Mak Class 101‚ Nanyang Girls’ High School‚ 2 Linden Drive‚ Singapore 288683 ABSTRACT In this project‚ the relationship between the concentration of salt solution and the length of the potato strip that was immersed in it was investigated. Five strips of potato of the same length were placed in different Petri dishes that contained water of different salt concentration. They were left for twenty minutes and the length

Chloe Lindbom Regeneration of a Planarian Over Time Erin Davis Biology Mrs. Werfelman 5th Hour 10/09/2014 10/20/2014 Background: The planarian‚ also known as the flatworm‚ is a creature that live all over land‚ oceans‚ and freshwater. (Biggs‚ A.‚ Gregg‚ K.‚ Hagins‚ W.‚ Kapicka‚ C.‚ Lundgren‚ L.‚ Rillero‚ P.‚ 2002) The planarian has a threebranched digestive cavity. (Alvarado‚ 2004) Planaria range from 1/8 to 1 inch. (Alvarado‚ 2004) The planarian can be cut into many pieces and each piece will grow

TITLE: Toxicity Testing and Determining the LC50 INTRODUCTION: Our main objective for this experiment was to determine which three chemicals were going to be the most toxic to the brine shrimp by adding drops of vinegar‚ bleach and ammonia to the controlled water. We found that the vinegar was the most effective and the quickest. The ending results were very interesting when being compared to our hypothesis and we learned that some chemicals can react faster than others and each contains a different
