Earth And Space Science Flashcards
Planet closest to sun
Planet furthest from sun
Closest - mercury
Furthest- Neptune
Asteroid belt located btwn
Mars and Jupiter
My Very Educated Mother Just Served Us Noodles
Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune
Large system of stars, gas, and dust held together by gravity
Earth?
Galaxy
Milky Way
Massive star has collapsed, and has gravitational force so strong that light cannot escape
Black hole
Northern hemisphere tilted toward sun =
Summer
Crystalline structure - luster, hardness,density
Ex: talc, diamonds, topaz
*INORGANIC
Minerals
3 types of rocks
Igneous
Sedimentary
Metamorphic
_ rock
Tectonic processes, bring magma to surface
Igneous
_ rock
Rock fragments are compacted as a result of weathering and erosion
**COMPACTION
Sedimentary
_ rock
HEAT and PRESSURE change structure of pre-existing rocks
Metamorphic
Describes how light reflects off the surface of a mineral
Ex: dull, metallic, pearly and waxy
Luster
Earth lines up btwn moon and sun
Lunar eclipse
Moon moves btwn earth and sun
Solar eclipse
3 layers of earth outer to inner
Crust
Mantle
Core (inner and outer)
What created earths magnetic field?
Inner core spins at slightly different rates from the rest of the planet
Earths surface layer - including crust and upper layer of mantle
Lithosphere
Broken pieces of the earths crust
Float where ?
Tectonic plates
Asthenosphere
One giant land mass before broken into continents
Pangea
Movement of tectonic plates, shifting continents to cure t position
Continental drift
Ocean basins and new ridges formed by
Divergent plate boundary
Tectonic plates collide forming mountains or trenches
Convergent plate boundary
Plates slide against each other horizontally in opposite directions along a boundary
Transform plate boundary
Vents in the earths crust allowing molten rock to reach surface, located along edges of tectonic plates
Also found at hotspots
Volcanoes
Cone shaped volcano, made of lava, ash, rock, steep sides
Ex:
Composite (stratovovolcano)
Mt Fuji, my Rainer
Dome shaped volcano, gently sloped sides, made of fluid lava flows
Ex ?
Shield volcano
Mt. Kilauea
Earth is _ yrs old
4.5 billion
_ period
Plant and animals
*95% of life became extinct at the end
Paleozoic
Period _
Earth formation until life appeared
Precambrian
_ period
Age of dinosaurs
Large asteroid = extinction
Mesozoic
_ period
Current time period
Humans, mammals, birds, flowering plants
Cenozoic
Occurs when hot magma cools and develops crystals and hardens
Crystallization
Energy released during an earthquake =
Magnitude
