GRAVITY ANOMALY Meaning and
Definition
-
A gravity anomaly refers to the deviation from the expected or normal gravity field of a particular region or structure on the Earth's surface. It is a measure of the variation in gravitational acceleration caused by variations in the density distribution beneath the Earth's surface.
In essence, the gravitational field on Earth is not constant due to differences in geological structures and materials below the surface. These variations can result from variations in rock types, densities, and distribution of contributing mass. As a result, the gravity field varies slightly from place to place, leading to the creation of gravity anomalies.
Gravity anomalies are typically measured using sensitive instruments such as gravimeters or by utilizing satellite-based measurements. They are expressed in units of milligals, where 1 milligal equals 0.01 millimeter per second squared.
Gravity anomalies have significant applications in geophysics and geology. They provide valuable information about subsurface features, such as buried geological structures, mineral deposits, and oil and gas reservoirs. By studying the gravity anomalies, scientists and geologists can gain insights into the composition, thickness, and geometry of rock layers beneath the Earth's surface.
Overall, gravity anomalies play a fundamental role in understanding the Earth's subsurface characteristics and aid in various fields, including resource exploration, geological mapping, and earthquake studies.

Etymology of GRAVITY ANOMALY
The etymology of the word "gravity anomaly" can be broken down as follows:
1. Gravity: The word "gravity" comes from the Latin "gravitas", which means "weight" or "heaviness". It was first used in the late 16th century to refer to the force that attracts objects towards one another.
2. Anomaly: The term "anomaly" originates from the Greek word "anomalos", which means "uneven" or "irregular". It entered the English language in the late 17th century and refers to something that deviates from what is considered normal or expected.
Therefore, "gravity anomaly" refers to an irregular or abnormal variation in the gravitational field of a region, which can occur due to variations in the density of underground structures or mineral deposits.
