Abiotic - The nonliving part of an ecosystem like the water, rocks and sunlight
Acceleration - the speeding up of an object, the slowing down of an object or the change in direction of an object.
Action / Reaction Pair - the relationship between two objects where one object exerts a force on another, and the second object exerts an equal but opposite force back on the first object.
adaptation - a change in which an organism or species becomes better suited to its environment.
Air Masses - Large bodies of air with relatively uniform temperature, humidity, and pressure characteristics throughout. They are typically formed over specific source regions and acquire their properties from those regions.
Air Pressure - The force exerted by the weight of air molecules above a given area or surface. It is typically measured using a barometer and is an important factor in determining weather patterns.
Allele - The different versions of a trait (for example blue eye color or brown eye color)
Analogous structures - features in different species that have similar functions but evolved independently, not from a shared ancestor, due to similar environmental pressures or adaptive needs like the wings of an insect and a bird.
Anemometer - A meteorological instrument used to measure the speed and direction of wind.
Asexual Reproduction - a form of reproduction where a new individual is produced from a single parent, resulting in offspring that are genetically identical to the parent, as no fusion of gametes occurs
Atmospheric Pressure - The pressure exerted by the atmosphere at a given point, typically measured in millibars (mb) or inches of mercury (inHg).
Atomic Mass – the number of protons and neutrons in the nucleus of one atom of the element. Located under the elemental symbol (at the bottom of the element box on the periodic table).
Atomic Number – the number of protons contained in each nucleus of its atoms of the element. Located over the elemental symbol (at the top of the element box on the periodic table).
Atomic Theory States: A theory that states
All matter is composed of atoms
Atoms of a given element are identical
Atoms of different elements combine in simple whole-number ratios to form chemical compounds.
Applied Force - an outside force applied to an object by another object or person.
Axis - An invisible line that passes through an object on which it spins.
Back Door Cold Front - A type of cold front that moves from east to west, opposite to the usual direction of cold fronts. It often brings cooler air from the northeast.
Balanced force - forces that are equal in magnitude and direction. Balanced forces do not cause movement of an object.
Barometer - A device used to measure atmospheric pressure. It typically consists of a column of liquid (such as mercury) in a glass tube, which rises or falls depending on changes in atmospheric pressure.
Beaker - a big cup with a flat bottom and a spout for pouring, often made of glass or plastic
Binary Fission - A type of asexual reproduction in which a cell splits into 2 identical daughter cells. Bacteria usually reproduce this way.
Bioaccumulation - the buildup of absorbed chemicals and toxins in an organism over time.
Biomagnification - the process where toxins become increasingly concentrated as they move further and further up the food chain.
Biomass - renewable organic material that comes from plants and animals
Biotic - The living parts of an ecosystem
Blizzard - A severe weather condition characterized by low temperatures, strong winds (usually over 35 miles per hour), and heavy snowfall, leading to reduced visibility and dangerous travel conditions.
Bubbles - Gas that is formed during a chemical reaction. It is evidence of a chemical change.
Budding - A type of asexual reproduction in which an offspring develops from a parent cell and eventually breaks off to become its own organism.
