Primary porosity
~ - originally formed with the material, voids in sediment
Secondary porosity
~ developed after rock formation; fracturing, faulting, dissolution (fractures in granite,
caverns in limestone)
Factors influencing the storage and movement of groundwater
~ - Aquitard: An imperme...
- Mostly formed in Hadeon Eon (just after crust solidified & Earth cooled
enough, most water came from either degassing of rocks coming to surface
from molten interior or from comets)
- Mostly ocean water (97.2%)
The main driver of erosion is
✓✓✓✓~ water... groundwater gets heated (magma chamber) and moves through picking up

✓✓✓✓~ not renewable in time frames we talk ab and time frames of human consumption
The ozone layer blocks
✓✓✓✓~ deadly UV rays and makes life possible on the surface of the Earth
Weather occurs in the
,✓✓✓✓~ atmosphere
Movement of the atmosphere is driven by
✓✓✓✓~ the sun's energy
Local turbulence is driven by
✓✓✓✓~ heat exchange with water and land
Rainforests, desert, tundra, temperate zones are consequences of
✓✓✓✓~ solar radiation and atmospheric convection
Major climate control results from
✓✓✓✓~ interaction with the hydrosphere (ocean temps & currents)
The biosphere is mostly
✓✓✓✓~ plants, then bacteria
Humans are the first animals to
✓✓✓✓~ globally impact our planet
, Earth's system is powered by
✓✓✓✓~ energy from the sun and heat from Earth's interior
The crust is ____ and constantly ____
✓✓✓✓~ dynamic, changing
Lithification
✓✓✓✓~ The process that converts sediments into solid rock by compaction or cementation.
The crust is ____ to ____ thick below oceans and ___ to ____ thick on the
continents
✓✓✓✓~ The crust is 5 to 20 km thick below oceans and 30 to 70 km thick on the continents
The crust is composed mainly of
✓✓✓✓~ oxygen, silicon, aluminum, iron, calcium, magnesium, potassium, and many other
elements in small amounts
Sediment can be created from
✓✓✓✓~ - weathering, transport, deposition of igneous rock
- uplift, weathering, transport, deposition of sedimentary or metamorphic rock
