The glossary activity module enables participants to create and maintain a list of definitions, like a dictionary, or to collect and organise resources or information.
Glossaries have many uses, such as
- A collaborative bank of key terms
- A ‘getting to know you’ space where new students add their name and personal details
- A ‘handy tips’ resource of best practice in a practical subject
- A sharing area of useful videos, images or sound files
- A revision resource of facts to remember

The emergence of life forms emerging from non-living chemical systems. In contrast with spontaneous generation, abiogenesis is not a process that biologists think continues in a particular environment, such as a planet or moon, once a living system has emerged.
Synonyms: Autogenesis, Spontaneous Generation
Antonym: Biogenesis-the development of life from preexisting life

Abrasion is the physical process of rubbing, scouring, or scraping whereby particles of rock (usually microscopic) are eroded away by friction.
The term corrasion (as distinct from corrosion: chemical weathering) is really a synonym for abrasion, but only with respect to running water for the deepening of valley floors.
1. Abrasion (or “corrasion,” q.v.) by wind-borne particles at Djadokhta, Mongolia: cliffs of massive red sandstones of Cretaceous age (Berkey and Morris, 1927). (Courtesy of the American Museum of Natural History.)
2. Coastal abrasion occurs as breaking waves which contain sand and larger fragments erode the shoreline or headland. This removes material resulting in undercutting and possible collapse of unsupported overhanging cliffs.
In mathematics, an abscissa is the number whose absolute value (modulus) is the perpendicular distance of a point from the vertical axis. Usually this is the horizontal coordinate of a point in a two-dimensional rectangular Cartesian coordinate system.
The term can also refer to the horizontal axis (typically x-axis) of a two-dimensional graph (because that axis is used to define and measure the horizontal coordinates of points in the space).
An ordered pair consists of two terms—the abscissa (horizontal, usually x) and the ordinate (vertical, usually y)—which define the location of a point in two-dimensional rectangular space.
Absolute monarchy, or despotic monarchy, is a form of monarchy in which one ruler has supreme authority that is not restricted by any written laws, legislature, or customs.These are often, but not always, hereditary monarchies. In contrast, in constitutional monarchies, the head of state's authority derives from and is legally bounded or restricted by a constitution or legislature.
A system of government headed by a monarch as the only source of power controlling all functions of the state.
Synonyms: kingship, queenship
the absolute value of a number is the distance the number is from the zero point on the number line. The absolute value of a number or an expression is always greater than or equal to zero (i.e. nonnegative).
Example:-The absolute value of −9 is 9
A collective term for the scientific and cultural community engaged in higher education and research, taken as a whole.
The word comes from the akademeia just outside ancient Athens, where the gymnasium was made famous by Plato as a center of learning.
The definition of academia is the world within an educational community.
The college does not have any sports teams because its focus is solely on its academia.
Gail found the real world of business to be quite different from what she learned in academia.
Cara wanted to go to Harvard University because of the school’s great reputation in academia.
The change in an object's velocity over time, measured in distance per unit time per unit time (for example meters per second per second or m/s2). Compare to velocity. Acceleration (a) is calculated by dividing the change (symbolized by Δ, the Greek letter delta) in velocity (v) by the change in time (t):
a = Δv/ Δt.
This can also be written as:
a = v2-v1/ t2-t1, where v1 and t1 denote the starting velocity and time and v2 and t2 denote the ending velocity and time.
To illustrate, imagine a car speeding up (accelerating) from a stand still (0 meters/second) to a speed of 15 meters/seconds over the course of 5 seconds. The car's total increase in velocity is 15 meters/second. During each of the 5 seconds that the car is accelerating, its velocity increases by 3 meters/second until it reaches its top speed. (After one second the car is traveling at a velocity of 3 meters/second; after 2 seconds, it's traveling at a velocity of 6 meters/second, and so on). Therefore, the car's rate of acceleration is 3 meters per second per second or 3 m/s2. Using the equation above:
a = v2-v1/ t2-t1
a = 15-0 / 5-0
a = 15/5
a = 3 m/s2

Gravitational Accelaration - the acceleration on an object caused by the force of gravitation. Neglecting friction such as air resistance, all small bodies accelerate in a gravitational field at the same rate relative to the center of mass. This equality is true regardless of the masses or compositions of the bodies.
At different points on Earth, objects fall with an acceleration between 9.78 and 9.83 m/s2 depending on altitude and latitude, with a conventional standard value of exactly 9.80665 m/s2
[noun] The change in an object's velocity over time, measured in distance per unit time per unit time (for example meters per second per second or m/s2).
