Da EES 3.2

QuestionAnswer
water A chemical compound (H₂O) essential for life, made of two hydrogen atoms and one oxygen atom.
Polarity A property of a molecule where electric charges are unevenly distributed, giving it positive and negative ends (water is polar).
Surface tension The force that makes the surface of water act like a stretched skin due to cohesion between water molecules.
Capillary action The ability of water to move upward through narrow spaces against gravity because of cohesion and adhesion.
Cohesion Attraction between molecules of the same substance (water sticking to water).
Adhesion Attraction between molecules of different substances (water sticking to other materials).
Capacity The ability of a substance to hold or store something, such as heat or energy.
Temperature A measure of how hot or cold something is, related to the average motion of its particles.
Agent Something that causes change or produces an effect (e.g., water as an agent of erosion).
Climate The long-term average pattern of weather in a region.
Heat Thermal energy that moves from a warmer object to a cooler one.
Convection The transfer of heat by the movement of fluids (liquids or gases)(circle movement).
Energy transfer The movement of energy from one place or object to another.
Store To hold or keep energy or matter for later use
Absorb To take in energy or matter.
Transmit To pass energy or matter through a material.
Energy The ability to do work or cause change.
Deep ocean The cold, dense water found far below the ocean surface.
Surface water The upper layer of the ocean that is warmer and more affected by sunlight and wind.
Coriolis effect The apparent bending of moving air and water caused by Earth’s rotation.
Specific heat The amount of heat needed to raise the temperature of a substance.
Density The amount of mass in a given volume.
Salinity The amount of salt dissolved in water.
Current A continuous, directed movement of water in the ocean.
Thermohaline circulation Global ocean circulation driven by differences in temperature (thermo) and salinity (haline).
Specific heat capacity The amount of heat required to raise the temperature of 1 gram of a substance by 1°C.
Latent heat Heat energy absorbed or released during a phase change without changing temperature.
Evaporation The process by which liquid water changes into water vapor
Condensation The process by which water vapor changes into liquid water.
Energy circulations The continuous movement and transfer of energy through Earth’s systems.
Thermocline A layer in the ocean where temperature changes rapidly with depth.
Halocline A layer in the ocean where salinity changes rapidly with depth.
Melting The change of a solid into a liquid due to heat.
Freesing The change of a liquid into a solid when heat is removed.
Wave formation The creation of waves, usually caused by wind transferring energy to water.
Heat transfer The movement of thermal energy from one object or area to another.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
