METEORITE
-Are rocks from space that have survived their passsage through the atmosphere to land on earth's surface.
DESCRIPTION OF A VOLCANIC CRATER
-round
-smaller
-above surrounding
-no overlapping
-volcanic debris
-igneous
5 FACTORS AFFECTING CRATER FORMATION
-Angle, speed, mass, surface area, target surface
STONY METEORITES
-Includes condrites and achondrites
-May include carbonaceous grains
STONY METEORITES
-May have potential to show early history of the solar system
STONY METEORITES
-Are divided into chondrites and achondrites based on wether they conatin small round balls of silicate minerals called Chondruled.
STONY METEORITES
-Silicate composition, shiny or rust interior or glassy fusion crust. Most common meteorites
IRON METEORITES
-Metal composittion
-Identified by density
-very rare in Antarctica, but otherwise represent 50% of others finds
IRON METEORITES
-Are stronger than stony meteorites; therefore, they don't break up easily in space or as they pass through the atmosphere.
METEOR FALL
-Meteorite composed of mainly iron rarely break up on entry.
3 PIECES OF INFORMATION GIVEN IN A METEORITE NAME
-Are named after the nearest town (Noblesville, IN)
-Post office so their names are often picturised
CAPTURE THEORY
-Proposes that as the solar system was forming, a large object ventured too near to the forming earth, became trapped into gravitational pull and formed the moon.
SIMULTANEOUS THEORY
-The moon and the earth formed at the same time and in the same general area, and thus the material which they were essentially the same.
IMPACT THEORY
-The moon formed as the result of a gigantic collision between earth and mars-sized object about 4.5 billion yrs ago.
METEORITE
-Are rocks from space that have survived their passsage through the atmosphere to land on earth's surface.
DESCRIPTION OF AN METEORITE CRATER
-Dimple
-Rim
-ejecta

RELATIVE DATING
-Identifying a surface as being "younger" or "older" than another
SUPERPOSTION AND CROSS-CUTTING
-super position: a surface on top of another is younger than the one it over laps.
-cross-cutting: the feature that is "cut through" is older than the feauture thats doing the cutting.
DENSITY
-how much mass exsist in a particular volume
-how tightly packed molecules are
-rock ~ 3.5g/cm3
-ice ~ 1g/cm3
-nixture~2g/cm3
ALBEDO
-how bright the surface is based on % of sunlight reflected.
-if bright, most likely more icy
-if low, most likely rock and ice or rock (defines day and night orbit).
ALBEDO OF AN ICY PLANET
-Alaska
ALBEDO OF A ROCKY PLANET
-Montana
WHAT DETERMINES ALBEDO
-the sunlight determines albedo.
GRADATION
-ex: erosion ,weathering, deposition , landslides, running H2O on earth: grand canyon on mars: valles mariners, visible on older surface on venus.
TECTONISM
-formhighlands, ridges (mountains)
-can cause land to be streched or uplifted
VOLCANISM
-caused by a warm interior
-creates smooth, dark maria (lava flows)
-caldera irregular crater of a very large volcano.
HOW AIR MOVES IN THE NORTHERN HEMISPHERE
-north: counter clockwise (right curve)
HOW AIR MOVES IN THE SOUTHERN HEMISPHERE
-south: clockwise (left curve)
AIR MOVES FROM_ TO_ PRESSURE
-air moves from high =low pressure (low=high temperature)
-occurs in all atmosphere and planets
-can create convection (cool)
warm
CORIOLIS EFFECT
-affect of a planet's rotation causing friction on the air, causing it to curve
-without coriolis:high =low straight
-with coriolis:high curved low
