Plates tectonic
where are transform faults Located?
earthquakes
mix of geologic and organic component
What is soil?
what is porosity?
The pore space within a soil ( more sand, more porous)
What is mesosphere?
Temp. Increases because top layer of stratosphere is warmed by UV rays
what is gyres?
Large ocean circ. Patterns due to global wind
Plates move to wards each other, leads to subduction (one plate being forced beneath another ) when one plate is oceanic.
Convergent plate boundary?
What is erosion?
Transporte of weathered rock fragments by wind and rain
What are the things can effect on soil fertility ?
Soil that is too sandy drain water too quickly fro roots and dries out, ideal soil fro most plant growth is loam, which balance porosity or drainage, with H2O holding cap
what is troposphere?
Temp. Increases due to absorption of highly energetic solar radiation
What is upwelling zones?
Areas of ocean where winds blow warm surface water away from a land mass, drawing up colder to replace it
What happen when stress overcomes the locked fault?
Plates suddenly release, slides past each other and releas energy that shakes the lithosphere.
What is soil formation from below?
Weathering of parent material produces smaller, and smaller fragments that make up geological and inorganic part of soil.
What is soil fertility?
Ability do soil to support plant growth
What is solar intensity & season?
Orbit of earth around sun& tilt on axis changes angle of sun rays.
What way does the warm water from Gulf of Mexico moves?
North Pole
What is Divergent plate boundary?
Plats move away from each other, rising magma plume from mantle forces plates apart
What is soil formation from above?
Breakdown of organic adds humus to soil, erosion deposits soil particles from other areas, adding to soil
factors that increase soil nutrient?
Organic matter, humus, decomposed, clay, bases
What is June & December solstices?
N or S hemispheres is maximally towards sun ( summer/winter )
What is ENSO?
Pattern of shifting atmosphere pressure & ocean currents in the Pacific Ocean between South America and Australia and South Africa.
dense oceanic plate subducts beneath cont.plate&melt back into magma.
What is an Oceanic-continental?
What are the effects soil form?
Parent material, topography, climate, organism
Factors that increase H2O holding cap?
Aerated soil, compost, humans, organic matter, clay content, root structures, especially natives
Tilt of earth’s axis causes variation in?
Angle of insertion, length of day, season
trade winds blow eq. Water
