Some Book Review Flashcards
Plate boundaries
1-convergent boundary
2-divergent boundary
3-transform fault boundary
1-2 plates pushed together (subduction volcanos)
2-2 plates moving away fro each other (rift volcanos)
3-2 plates slide by each other
What is subduction
Heavy ocean plate is pushed below the other plate and melts as it meets magma
Volcano types
1-rift
2-subduction
3-hot spot
1- 2 plates move away for each other
2-2 plates collide
3- found in hotspots
Igneous rocks
Rock is melted and the resolidifies
Ex- solid lava, basalt
Sedimentary rocks
Sediment compressed by heat and pressure
Ex-limestone
Metamorphic rocks
Heat and pressure applies
Ex-slate
Abiotic vs. biotic
A-non living
B-living
Particle size
Soil
Clay- silt- sand
Weathering
- physical
- chemical
- biological
Physical- wind and water
Chemical- water and atmospheric gases
Biological- activities of living organism
Soil levels O-horizon A-horizon E horizon B C R
O- top (humus) and most organic material
Monoculture
Plating one crop in a large area continuously
Soil and water conservation act of 1977
Help landowners
Atmosphere (coolest to earth)
Thermosphere Mesosphere Stratosphere Troposphere EARTH SURFACE
Troposphere
Weather takes place here
-temp down as elevation increases
Stratosphere
Ozone layer
-temp goes up with altitude
Mesosphere
Meteors burn up here
Thermosphere
Spaceships orbit here
Weather vs climate
Weather- day to day
Climate- change that is persistent over 30 years
Earths tilt access
23.5 degrees
Trade winds
Northern hemisphere - from northeast
Southern hemisphere -from southeast
El niño
Cold water displaces warm water on surface
Us-warmer winters
La Nina
Colder ocean surfaces
-cooler wetter in us
Littoral zone (freshwater) Limneric zone (ample light) Profundal zone (dark) Benthic zone (low oxygen and low temp)
Where rooted plants grow
Ocean zone
Coastal zone -closest to land
Euphoric zone -warmest, most dissolved oxygen
Bathyal zone -middle
Abyssal zone -deepest, darkest, least sun, least oxygen
Look at front
Water is desist at ?
4 degrees Celsius
Water us percents
Irrigation- 73%
Industrial -21%
Biogeochemical cycle
Movement of nutrients through the environment
Law of conservation of matter
Can’t be created or destroyed
Carbon cycle
Respiration (animals and plants)
Photosynthesis
Produced by burning fossil fuels and decaying organic matter
Nitrogen cycle
Fixation- nitrogen converted to ammonia
Nitrification- soil bacteria converts ammonia into nitrate(plant food)
Assimilation- plants absorb ammonia
Ammonification-decomposes create ammonia
Denitrification- ammonia converted back into nitrates
Phosphorus cycle
Animal and fertilizer run off
-eutrophication (algae bloom)
Autotrophs vs heterotrophs
Auto- produce own organic compounds
Hetero- consume other organisms for food
How do tectonic plates move?
The lithosphere (land) floats atop the asthenosphere (ground)
How much energy is lost at each step in the pyramid
90%
Biomes vs zones
Biomes- land based ecosystem
Zones- water based ecosystem
Ecosystems based on rainfall (high to low)
Tropical rainforest Deciduous forest Scrub forest Coniferous forest Grassland Tundra + deserts
Symbiotic relationship
Probably benefit both parties
Mutualism relationship
Both benefit
Commensalism
One benefits, other not harmed
