APES Review 1 Earth Systems and
Resources Exam Questions and
Answers9
illuvation - ANSWERS-deposit of leached material in lower soil layers (B)
monoculture - ANSWERS-A large expanse of a single crop; more efficient, increases output;
devastates biodiversity; susceptible to disease and pests; narrows human diet.
green revolution - ANSWERS-The introduction of pesticides and high-yield grains and better
management during the 1960s and 1970s which greatly increased agricultural productivity.
organic fertilizers - ANSWERS-The remains/wastes of organisms; decay process of organics
makes them slow-acting and long-lasting; not as soluble because they are more complex.
crop rotation - ANSWERS-Planting a field, or an area of a field, with different crops from year to
year to reduce soil nutrient depletion. A plant such as corn, tobacco, or cotton, which removes
large amounts of nitrogen from the soil, is planted one year. The next year a legume such as
soybeans, which adds nitrogen to the soil, is planted.
drip irrigation - ANSWERS-a proccess by which pipes placed near plant roots drip only as much
water as the plants need.
contour plowing - ANSWERS-plowing fields along the curves of a slope to prevent soil loss
earth's interior - ANSWERS-solid crust, semi-solid mantle, liquid core, solid core
, lithosphere - ANSWERS-the solid part of the earth consisting of the crust and outer mantle
tectonic plates - ANSWERS-Sections of the Earth's crust that move due to convection currents.
oceanic plate - ANSWERS-This is a tectonic plate that is a thinner, denser and heavier type
continental plate - ANSWERS-Thicker but lighter plate that makes up most continents
plate boundaries - ANSWERS-the edges of tectonic plates.
convergent - ANSWERS-a boundary where earth's tectonic plates move toward each other. This
causes a collision or subduction. This will result in the formation of volcanoes and mountain
ranges.
divergent - ANSWERS-plates move apart
transform - ANSWERS-Plates slide past each other
subduction - ANSWERS-a geological process in which one edge of a crustal plate is forced
sideways and downward into the mantle below another plate
focus - ANSWERS-The point beneath Earth's surface where rock breaks under stress and causes
an earthquake
epicenter - ANSWERS-the point on the Earth's surface directly above the focus of an earthquake
seismograph - ANSWERS-a measuring instrument for detecting and measuring the intensity and
direction and duration of movements of the ground (as an earthquake)
