Earth And Space Sciences:
SEASONS- Created by the tilt of the earth when the northern and southern hemispheres
are either tilted away, towards or equally angled from the sun’s most direct rays.
ROTATION- A planetary body such as the earth spinning on its axis like a globe as you
REVOLUTION- This is when a planet, like earth, makes one complete trip around the
sun (360 degrees).
LIGHT YEAR- The distance light travels in one year. It equals 5.879x 10^12 miles or
TIDES- The alternate rising and falling of the surface of the ocean and water bodies
(such as gulfs and bays) connected with the ocean that occurs usually twice a day, and is
caused by the gravitational attraction of the sun and moon occurring unequally on
different parts of the Earth.
GRAVITATION- A force manifested by acceleration toward each other of two free
material particles or bodies , or of radiant-energy quanta.
ORBIT- A path described by one body in its revolution about another ( as by the Earth
about the sun or by an electron about an atomic nucleus).
COMET- A celestial body that consists of a fuzzy head usually surrounding a bright
nucleus, that has a usually highly eccentric orbit, and that often, when in the part of its
orbit near the sun , develops a long tail which points away from the sun.
ASTEROID- A small rocky body orbiting the sun.
METEOR- Any of the small particles of matter in the solar system that are directly
observable only by their incandescence from fictional heating on entry into the
METEOROID- One of a large number of celestial bodies of various size that appear as
meteors when they enter Earthí’s atmosphere.
Physical Sciences :
Reflection: Notes from class
Refraction: Notes from class.
SPEED- The distance traveled divided by the time interval during which the motion
WAVE- A periodic disturbance in a solid, liquid, or gas as energy is transmitted through
SOUND WAVES- Mechanical radiant energy that is transmitted by longitudinal pressure
waves in a material medium ( such as air) and is the objective cause of hearing.
MOTION- An act, process or instance of changing position through time.
Bending of sound and light. Ex. Sound able to be heard around a corner rather then continuing in a straight line.
FAULTING- To fracture, so as to produce a geologic fault.
FOLDING- Causing rock strata to undergo bending or curvature.
CONVERGENT- To come together or tend to come together at a point.
DIVERGENT- To separate or spread apart.
TECTONIC PLATES- The earth’s top layer (crust) that shifts and moves on top of the
EROSION- Weathering of earthí’s surface by forces of nature such as wind and water.
This is when soil or rock material (sediments) are taken away from an area. Can also be
caused by human activity.
FOSSIL- Remnant, impression or trace of an organism of past geologic ages that has
been preserved in the Earthí’s crust.
EXTINCT- A species of organisms that no longer exists.
ASEXUAL REPRODUCTION- Involving or reproducing by reproductive processes( as
cell division , spore formation, fission or budding) that do not involve the union of germ
cells or egg and sperm.
