How do you describe geologic history?
The geologic time scale is a standard timeline used to describe the age of rocks and fossils, and the events that formed them. It spans Earth’s entire history and is typically divided into four principle divisions.
How was India formed geologically?
Previous estimates have suggested this collision occurred about 50 million years ago, as India, moving northward at a rapid pace, crushed up against Eurasia. The crumple zone between the two plates gave rise to the Himalayas, which today bear geologic traces of both India and Asia.
What is geological history of an area?
geologic history of Earth, evolution of the continents, oceans, atmosphere, and biosphere. The layers of rock at Earth’s surface contain evidence of the evolutionary processes undergone by these components of the terrestrial environment during the times at which each layer was formed.
Why is geologic history important?
In addition to providing a scientific basis for understanding the evolution of Earth over time, historical geology provides important information about ancient climate changes, volcanic eruptions, and earthquakes that can be used to anticipate the sizes and frequencies of future events.
What geological period are we?
Currently, we’re in the Phanerozoic eon, Cenozoic era, Quaternary period, Holocene epoch and (as mentioned) the Meghalayan age.
What are the geological region of India?
Geologically, India is divided into 3 major regions (also called the Triple Tectonic division): The Peninsular Plateau region – It also includes the Shillong Plateau and the Kutchch Kathiawar region (Outliers) The Extra-peninsular region – the mountainous region of Himalayas.
What is the geographical structure of India?
India is situated north of the equator between 8°4′ north to 37°6′ north latitude and 68°7′ east to 97°25′ east longitude. It is the seventh-largest country in the world, with a total area of 3,287,263 square kilometres (1,269,219 sq mi)….Geography of India.

Who named the geological periods?
The International Stratigraphic Commission, part of the International Union of Geological Sciences, gets to do the name calling; and it has just called in favour of the Ediacaran. This is a period that began 600m years ago, and ended 542m years ago.
Where is the geologic history of Earth recorded?
The geologic record is the history of Earth as recorded in the rocks that make up its crust. Rocks have been forming and wearing away since Earth first started to form, creating sediment that accumulates in layers of rock called strata.
What is the oldest geological period?
the Paleozoic Era
The oldest is the Paleozoic Era, which means “ancient life.” Fossils from the Paleozoic Era include animals and plants that are entirely extinct (e.g., trilobites) or are rare (e.g., brachiopods) in the modern world.
What is the first geological period?
The first eon was the Hadean, starting with the formation of the Earth and lasting about 540 million years until the Archean eon, which is when the Earth had cooled enough for continents and the earliest known life to emerge.
What is the geological history of India?
Peninsular India was a part of the old landmass since the formation of the Earth’s Crust
What is the geological structure of India?
Geological Structure of India (NCERT Notes) The Peninsular Block The Himalayas and other Peninuslar Mountains Indo-Ganga-Brahmaputra Plain.
What kind of Technology is used in geology?
Infrared technology can help scientists to predict volcanic eruptions, and to search for gold and silver hidden in the ground. The same technology used to study geology on the Earth is also used to study Venus and Mars.
What is involved in the study of geology?
Geology is the study of the Earth, the materials of which it is made, the structure of those materials, and the processes acting upon them. It includes the study of organisms that have inhabited our planet. An important part of geology is the study of how Earth’s materials, structures, processes and organisms have changed over time.
