1. Most of Earth's mass is contained in the
2. The idea of a spreading sea floor along the Mid-Atlantic ridge is supported by
changes in the orientation of magnetized minerals.
waveChapter 8 Atoms and Periodic Properties Notes Key Terms: 1. atomic mass unit It is impossible to find the mass of a given atom. In order to compare the mass of one atom to another you compare the mass of any atom to the mass of an atom of a particular
Some Important Reminders:
PE (potential energy) is: mass x gravity x height, or, mgh
KE (kinetic energy) is: mass x velocity squared, or, 1/2mv2
Work is: force x distance, or, Fd
Force is: mass x acceleration, or, ma
Weather and CLIMATE
1. How does the average amount of water that returns to the oceans by precipitation
compare to the water that leaves by evaporation?
Evaporation is greater than precipitation.
Precipitation and evaporation are equal.

Chapter 19 Building Earth's Surface: Notes
1. anticline In general an arch-shaped folds is called an anticline. The most common region structures from deep plastic deformation are these arch-shaped and trough-shaped folds. Not always visible on earth's su
Chapter 7 Light: Notes
1. blackbody radiation Visible light emitted from incandescent sources at high temperatures produces electromagnetic radiation that is given off from matter at any temperature. Refers to an idealized material that prefectly absorbs
Chapter 13 Nuclear Reactions: Notes 1. alpha particle Ernest rutherford studied the nature of radioactivity and found there are thee kinds, alpha, beta, and gamma radiation. known to be the nucleus of a helium atom. Two protons and two neutrons. 2. backgr
Chapter 3: Energy Work 3.1 Work done on the object is defined as the products of the applied force and the parallel distance through which the force acts: work = force * distance W = Fd Mechanical work is the products of a force and the distance an object
Chapter 14 The Universe: Notes 1. absolute magnitude Used to calculate the brightness that stats would appear to have if they were all at a defined, standard distance (32.6 light-years). The brightness of a star at this distance is called absolute magnitu
1. Achondrites Do not have the chondrules as their name implies, but have a homogeneous texture more like volcanic rocks such as basalt that cooled from molten rock. 2. asteroids Between the orbits of Mars and Jupiter is a belt or circular region of thous
Chapter 18 Plate Tectonics: Notes 1. asthenosphere low velocity zone that is hot, elastic semiliquid layer that extends around the entire earth. Named after Greek word for weak shell. Seismic waves undergo a sharp decrease in velocity at this level. 2. co
Chapter 22 The Atmosphere of Earth: Notes 1. absolute humidity measurement of the amount of water vapor in the atmosphere at a particular time is called absolute humidity. 2. barometer used to measured atmospheric pressure. Invented in 1643 by Italian nam
Chapter 23 Weather and Climate: Notes 1. air mass a large horizontally uniform body of air with nearly the same temperature and moisture conditions. Forms when a large body of air, perhaps covering millions of square kilometers, remains over a large area
