EXAM 2024\2025 |GUARANTEED
PASS
Abiotic - ACCURATE ANSWERS✔✔ Pertaining to factors or things
that are nonliving.
Acid - ACCURATE ANSWERS✔✔ Any compound that releases
hydrogen ions when dissolved in water. Also, a water solution that
contains a surplus of hydrogen ions.
A horizon - ACCURATE ANSWERS✔✔ a soil horizon; the layer below
the O layer is called the A layer. The A layer is formed of weathered
rock, with some organic material; often referred to as topsoil.
Alkaline - ACCURATE ANSWERS✔✔ a basic substance; chemically, a
substance that absorbs hydrogen ions or releases hydroxyl ions; in
reference to natural water, a measure of the base content of the water.
Aquifer - ACCURATE ANSWERS✔✔ an underground layer of porous
rock, sand, or other material that allows the movement of water between
layers of nonporous rock or clay. Aquifers are frequently tapped for
wells.
Arable - ACCURATE ANSWERS✔✔ land that's fit to be cultivated.
,Asthenosphere - ACCURATE ANSWERS✔✔ the part of the mantle that
lies just below the lithosphere.
Atmosphere - ACCURATE ANSWERS✔✔ the gaseous mass or
envelope surrounding a celestial body, especially the one surrounding
the Earth, which is retained by the celestial body's gravitational field.
Barrier island - ACCURATE ANSWERS✔✔ a long, relatively narrow
island running parallel to the mainland-built up by the action of waves
and currents and serving to protect the coast from erosion by surf and
tidal surges.
Biological weathering - ACCURATE ANSWERS✔✔ any weathering
that's caused by the activities of living organisms.
Biotic - ACCURATE ANSWERS✔✔ living or derived from living
things.
B horizon - ACCURATE ANSWERS✔✔ a soil horizon; B receives the
minerals and organic materials that are leached out of the A horizon.
Chemical weathering - ACCURATE ANSWERS✔✔ the result of
chemical interaction with the bedrock that is typical of the action of both
water and atmospheric gases.
,C horizon - ACCURATE ANSWERS✔✔ a soil horizon, horizon C is
made up of larger pieces of rock that have not undergone much
weathering.
Clay - ACCURATE ANSWERS✔✔ the finest soil, made up of particles
that are less than 0.002 mm in diameter.
Convection - ACCURATE ANSWERS✔✔ the vertical movement of a
mass of matter due to heating and cooling; this can happen in both the
atmosphere and Earth's mantle.
Convection currents - ACCURATE ANSWERS✔✔ air currents caused
by the vertical movement of air due to atmospheric heating and cooling.
Convergent boundary - ACCURATE ANSWERS✔✔ a plate boundary
where two plates are moving toward each other.
Coral reef - ACCURATE ANSWERS✔✔ an erosion-resistant marine
ridge or mound consisting chiefly of compacted coral together with algal
material and biochemically deposited magnesium and calcium
carbonates.
Coriolis effect - ACCURATE ANSWERS✔✔ The observed effect of the
Coriolis force, especially the deflection of an object moving above the
Earth, rightward in the Northern Hemisphere, and leftward in the
Southern Hemisphere.
, Crop rotation - ACCURATE ANSWERS✔✔ the practice of alternating
the crops grown on a piece of land - for example, corn one year, legumes
for two years, and then back to corn.
Delta - ACCURATE ANSWERS✔✔ a usually triangular alluvial deposit
at the mouth of a river.
Divergent boundary - ACCURATE ANSWERS✔✔ a plate boundary at
which plates are moving away from each other. This causes an upwelling
of magma from the mantle to cool and form new crust.
Doldrums - ACCURATE ANSWERS✔✔ a region of the ocean near the
equator, characterized by calms, light winds, or squalls.
Drip irrigation - ACCURATE ANSWERS✔✔ a method of supplying
irrigation water through tubes that literally drip water onto the soil at the
base of each plant.
Earthquake - ACCURATE ANSWERS✔✔ the result of vibrations (often
due to plate movements) deep in the Earth that release energy. They
often occur as two plates slide past one another at a transform boundary.
El Nino - ACCURATE ANSWERS✔✔ a climate variation that takes
place in the tropical Pacific about every three to seven years, for a
duration of about one year.
