Ecologies and Environments Artize L. Johnson Professor: Denise Stiglich SCI 110 Introduction to Physical Science 4 March 2012 1. Describe your local and surrounding ecologies and environments. Before we can describe the local and surrounding ecologies and environments‚ we have to know the meaning of ecology and environment. The relation among organisms and the environment that they are in is called ecology. During an organism’s lifetime

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

The moon The moon is the only natural satellite of Earth. The moon orbits the Earth from 384‚400 km and has an average speed of 3700 km per hour. It has a diameter of 3476 km‚ which is about ¼ that of the Earth and has a mass of 7.35e22 kg. The moon is the second brightest object in the sky after the sun. The gravitational forces between the Earth and the moon cause some interesting effects; tides are the most obvious. The moon has no atmosphere‚ but there is evidence by the United States

asteroid. Until the first successful Mars flyby in 1965 by Mariner 4‚ many speculated about the presence of liquid water on the planet’s surface. This was based on observed periodic variations in light and dark patches‚ particularly in the polar latitudes‚ which appeared to be seas and continents; long‚ dark striations were interpreted by some as irrigation channels for liquid water. These straight line features were later explained as optical illusions‚ though geological evidence gathered by unmanned

It takes a lot more than a few men and a bundle of wood built into a boat to travel around the entire world. Many explorers of this time period risked their lives to discover the land walked by many people today. The discoveries and gadgets made by these people have contributed positively to the voyages across the ocean today. Not only have they made it easy‚ they have also made it different in so many ways! The time period lasting between the 1500’s and the 1700’s‚ also known as the age of exploration

Extended Response Writing in HSC Geography There are two parts to approaching an extended response: 1. Reading the question 2. Writing the response 1. Reading the Question By effectively reading the question you find out what FACTS and TOPICS are required how the examiners want you to answer it. 3 How do I effectively read the question? 4 Determine what syllabus dot point it is from? All questions are based on a syllabus dot point. Once you can recognise

The Sonoran occupies 100‚000 square miles along the two countries. The Sonoran is the result of a rain shadow desert being bordered by the Peninsular Ranges in California as well as being in a latitude around 30 being effected by the Subtropical high. The Subtropical high is an area from the 20 -40 latitude where air subsides by compression leading to a temperature inversion and acts as a barrier to vertical convection and is largely responsible for aridity in the region. Unlike the Mojave‚ the Sonoran

Hydrosphere The movement of water around‚ over‚ and through the Earth is called the water cycle‚ a key process of the hydrosphere. In physical geography‚ the term hydrosphere (Greek hydro means "water") describes the collective mass of water found on‚ under‚ and over a planet’s surface. The Earth’s hydrosphere consists chiefly of the oceans‚ but technically includes clouds‚ inland seas‚ lakes‚ rivers‚ and underground waters. Hydrosphere refers to that portion of Earth that is composed of water. The

1. As seen from temperate or tropical latitudes‚ the positions of the constellations shift gradually westward in the sky from night to night because (a) the Earth rotates on its axis. (b) the Earth revolves around the Sun. (c) the tilt of the Earth’s axis changes. (d) their right ascensions constantly change. (e) their declinations constantly change. 2. A star cluster in which the individual stars do not show a striking central concentration nor an orderly pattern or structure is

Give an example of each scale of atmospheric motion; Micro‚ Meso and Macro. An example of a “Microscale” atmospheric motion would be a small‚ turbulent breeze blowing through the trees. A F3 tornado flowing across a Kansas corn field would be an example of a “Mesoscale” motion‚ and Super Storm Sandy would be a great example of a “Macroscale” motion. What causes an "eddy" to form? An “eddy” is formed when wind encounters a solid object‚ a whirl of air is formed on the object’s downward side. The
