Science

A water having more salinity than freshwater, but not as much as seawater

Brackish

A water having more salinity than freshwater, but not as much as seawater. Brackish. Brackish water is a mixture of freshwater and seawater, found in areas like estuaries where rivers meet the ocean.

The attraction between molecules of the same substance

Cohesion

The attraction between molecules of the same substance. Cohesion. Cohesion is the force that holds molecules of the same material together, like water droplets sticking to each other.

The ability of a material to let heat or electricity pass through

Conductivity

The ability of a material to let heat or electricity pass through. Conductivity. In simple terms, conductivity is how well a material can allow heat or electricity to flow through it.

The process in which rock is worn away and transported by water, wind or ice

Erosion

The process in which rock is worn away and transported by water, wind or ice. Erosion is when natural forces like water, wind, and ice wear away and move pieces of rock and soil.

An area where fresh river water mixes with salty ocean water

Estuary

An area where fresh river water mixes with salty ocean water. Estuary. An estuary is a coastal area where freshwater from rivers blends with salty sea water, creating a unique environment for diverse wildlife.

The attraction between oppositely charged ions

Ionic bond

The attraction between oppositely charged ions. Ionic bond. An ionic bond is when two atoms stick together because one gives away electrons and the other takes them, making them charged and attracted to each other.

The maintenance of constant osmotic pressure in the fluids of an organism

Osmoregulation

The maintenance of constant osmotic pressure in the fluids of an organism. osmoregulation. Osmoregulation is the process by which organisms maintain the balance of water and salts in their bodies.

The diffusion of water through a semipermeable membrane

Osmosis

The diffusion of water through a semipermeable membrane. osmosis. Osmosis is the movement of water from an area of low solute concentration to an area of high solute concentration through a semipermeable membrane.

The amount of salt dissolved in water

Salinity

The amount of salt dissolved in water. Salinity. Salinity is the measure of how much salt is present in water.

A measure of how much solute will dissolve in a solvent

Solubility

A measure of how much solute will dissolve in a solvent is solubility. Solubility is the ability of a substance to dissolve in a liquid, forming a solution.

The substance that is dissolved to form a solution

Solute

The substance that is dissolved to form a solution. Solute. A solute is what you dissolve in a liquid to make a mixture, like sugar in water.

A mixture of evenly distributed substances

Solution

A mixture of evenly distributed substances. Solution. In Science, a solution is a homogeneous mixture of two or more substances where one is dissolved in the other.

The substance in which another substance is dissolved

Solvent

The substance in which another substance is dissolved. solvent. A solvent is a liquid that dissolves other substances to form a solution.

The force acting on particles at the surface of a liquid

Surface tension

The force acting on particles at the surface of a liquid surface tension. Surface tension is a property of liquids where the surface behaves like a stretchy skin due to the attraction between molecules.
