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.
|
|

|
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 |
