Climate
What is the set of physical conditions of the lower atmosphere called?
Weather
In what biome would you find broadleaf plants and lots of rain?
Tropical Rainforest
(think about forests, deserts, grasslands)
Living with chronic hunger and poor nutrition is called?
Food insecurity
What is a mineral?
A naturally occurring inorganic solid that has a regularly repeating internal arrangement of atoms.
What is a partially enclosed body of water where rivers meet the sea?
Estuaries
What is the difference between latitude and longitude?
Lines of longitude trend N-S, but we discuss as E or W of the prime meridian
Lines of latitude trend E-W, but we discuss as N or S of the equator
What is the dimly light middle zone of the ocean?
The bathyal zone
Growing several crops in the same plot of land simultaneously is known as:
polyculture
What layer of the earth do we live on?
Crust or lithosphere
Lithosphere = crust and top bit of mantle
What is a large terrestrial region characterized by a particular type of climate and dominant plant life?
Biome
Where on the earth is highest solar energy received?
Equator
What Ecosystems Services do Marine ecosystems provide?
Nutrient cycling
CO2 absorption
Biodiversity (species and habitats)
Oxygen through photosynthesis
Storm reduction
What are the disadvantages and advantages of synthetic pesticides?
Pros: expand food supplies, raise profits, work fast, safe if used properly
Cons: promote genetic resistance, kill pests' natural enemies, harm people/wildlife, pollute air/water/land, & expensive
What is an ore?
What is the difference between a high-grade ore and a low-grade ore
A rock that contains a high enough concentration of a mineral to make it profitable to mine and process
High grade ore = high concentration
Low grade ore = low concentration
What is precipitation that does not sink into the ground or evaporate?
Surface water
What are ocean currents?
Mass movements of surface ocean water driven by winds and shaped by landforms
Why are mountains important to Biodiversity?
What is one way farmers have used cross breeding?

(often strip mining)

El Nino
Consequences:
Drought in Australia and Southeast Asia
Warmer water continues deeper off the coast of South America
What do the human inputs of nutrients from urban and agriculture areas within a lake's watershed create?
Cultural eutrophication
What are the 4 types of soil conservation that we discussed?
Terracing
Strip cropping
Alley cropping
Windbreaks
What are some of the harmful environmental issues associated with mining and processing ore?
Tailing piles (rock wastes that are left in pile/ponds)
Smelting, heating the ores, releases pollutants
What are some advantages of Aquaculture?
High efficiency
High yield
Reduces over-harvesting
