What is the word delta mean in science?

Answer 1

The answer depends on the context.

Delta is a letter of the Greek alphabet and is shaped like a triangle. Mouths of rivers, which are often triangular in shape are, therefore, also called deltas.

In mathematics, delta is often used to denote a change, particularly a small change.

There is also the Dirac delta function which is an asymptotic spike function and is used in quantum physics.

Answer 2

Delta is the unit representing change over time and is usually represented by a triangle.

ex: v∆t= 23m/s is a measure of rate of acceleration change - the object measured is increasing in velocity or accelerating an additional 23 meters every second.

Answer 3

In geography, a delta--or more accurately a river delta--is the land that is formed from the deposit of silt at the mouth of a river.

Delta can also refer to the symbol or letter in the Greek alphabet: Δ or δ in the Greek alphabet. It is also used as a mathematical symbol.

Answer 4

A delta is a low triangular area of alluvial deposits where a river divides before entering a larger body of water; "the Mississippi River delta"; "the Nile delta"

Answer 5

End of a river where sediment is deposited.

Answer 6

land that forms at the mount of a river and empties it in a ocean, sea, ect.

Answer 7

Delta is a symbol that denotes a change in something. In physics the delta-v is used to calculate the change in velocity, or change in velocity over time.
