Acid Substance that dissolves rock
Adaptation Changes that help an organism survive and reproduce
Agricultural Having to do with farming
Aquatic Having to do with water
Aquifer Underground water storage
Asexual Reproduction Reproduction by one parent
Beach Area along the shore covered with weathered rock bits
Biodiversity A variety of living things
Biomass Living or once living matter
Biome Specific location with specific climate, plants, and animals
Canyon Area carved into the earth's surface by river erosion
Catastrophe Any misfortune, in this case, a sudden disaster
Chemical Weathering Acid rain or oxidation
Chromosomes Structures that hold the DNA (genes)
Climax Community Final, stable stage of ecological succession
Compost Decaying matter (Temp. increases during process)
Condensation Water turning from vapor to liquid
Consumer An organism that eats other things for energy
Contraction Shortening
Delta Area of deposition caused by the slowing of water
Deposition Drops off eroding material
Dichotomous key Used to identify items with paired statements
Dissolution Break apart-usually in liquid
Dominant Trait Feature that is seen in organism (phenotype). Represented by a capital letter
Downstream Further in the direction the water flows
Dune Build up of sand or other material due to the wind
Earthquake Movement caused by plate tectonic
Ecological Succession Gradual changes to an ecosystem over time
Ecoregion A specific region with specific plants, animals, and climate
Ecosystem All the biotic and abiotic features in a particular area
Energy Pyramid Model showing energy movement in an ecosystem
Erosion Moving of weathered material
Evacuated Moved to another area
Evaporation Change of state from liquid to gas
Excessive Too much
Expansion Increase in amount or size
Exposed Showing, visible
Extensions Parts that stick out past the body
External Outside
Extremely A lot
Fertilizer Chemicals used to increase plant growth
Flood Too much water with nowhere to go to
Food Chain A chain showing the food source to a consumer
Food Web Shows overlapping food chains
Formation Something created e.g. cliff or canyon
Gene DNA, determines traits of an offspring
Geoligist Scientist who studies rocks and minerals
Geotropism Plant growth in response to gravity
Germinate Begin to grow
Glacier Huge mass of ice
Gradient Scale that goes up
Habitat Where a particular organism lives
Heredity Passing on of traits from parents to offspring
Hurricane Huge area of low pressure, giant storm
Impact Hit
Ingesting Take in
Intensity How strong or weak something is
Internal Inside
Mechanical Weathering Ice wedging, heating and contracting, plant roots, mass wasting
Mountain Built up pile of rocks
Mudslide Self-Explanatory
Natural Selection Breeding without human interference
Negative Opposite of; not good
Nucleus Structure in cell the holds chromosomes (like the brains!)
Nutrient Organic matter that provides needed materials for an organisms
Percolation Movement of water down through soil and rock
Phenomenom Event
Photosynthesis Process by which plants make sugar
Phototropism Plant growth in response to light
Pioneer Organism First organism in an area
Pollutant Something bad for the environment
Positive Good
Precipitation Water falling from the sky in any form
Primary Succession The first stage of succession. It's basically rock
Producer Plant
Recessive trait Not expressed trait. Represented by a lowercase letter
Response Reaction to a stimulus
Run-off Water moving downhill
Saffir-Simpson scale Rates the intensity of Hurricanes
Saturation Completely full
Secondary Succession The second stage of succession. It begins with soil
Sediment Broken down substances that have settled somewhere
Selective Breeding Human interference in the breeding process
Sexual Reproduction Reproduction that requires two parents
Stimulus An action that causes a response
Sustainability Continues on and on
Tornado Vortex of wind
Tributaries Smaller streams that feed into larger streams
Turgor Pressure Water pressure that help keep the plant upright
Volcano Location where molten rock emerges from the earth
Water Table Water level underground
Watershed Land area that provides run-off for a river
Weathering Breaking down of rocks by mechanical or chemical means
3 examples of Mechanical Weathering Freezing, Thawing, Wind Erosion, Wave Erosion, Heating and Contraction, Plant Roots, Gravity
1 type of Chemical Weathering Acid Rain, Oxidation
Why are adaptations necessary? Survival and Reproduction
Which carries more sediment, Fast Streams, or Slow Streams Fast Streams
What is the correct scientific term for downward movement of water through pores and spaces in the ground Percolation
What is the function of roots? Store Water, Absorb Nutrients and Water
What is the function of leaves? Make food
Which way should the arrows point in a food chain or food web? Toward the organism getting the energy (toward the eater)
3 ways humans affect the environment Water Pollution, Air Pollution, Land Pollution
