The Permian-Triassic (P-Tr) Extinction Event is widely recognised as the greatest extinction event on Earth. It is also known as the "Great Dieing".
It occurred 251 million years ago marking the end of the Permian Period and the start of the Triassic Period. It also marks the end of the Paleozoic Era and the start of the Mesozoic Era. Estimates have suggested that 96% of marine species and 70% percent of land vertebrate species became extinct. It is also the only known mass extinction of insect with 56% of insect families and 83% of insect genera becoming extinct.
Little is known of the cause of the mass extinction but theories range from meteorite impacts, to volcanism, to sea level fluctuations.

In which layer of the earth does the greatest atmospheric pressure occur?
The greatest atmospheric pressure occurs in the troposphere, which is the lowest layer of the Earth's atmosphere. The pressure decreases rapidly with height in the troposphere, and it is where weather events and phenomenon like clouds, rain, and storms take place.
What forces causes the earth's highest tides in the ocean?
The earth's highest tides are caused by the gravitational pull of the moon and sun on the earth's oceans. When the sun, moon, and earth are aligned during a full moon or new moon, their gravitational forces combine to create higher tides known as spring tides.
What has the greatest erosion power?
Water is generally considered to have the greatest erosion power among natural elements. Water erosion can occur in various forms such as river erosion, coastal erosion, and rain erosion, reshaping the Earth's surface over time.
Thunderlightingwindand rain occur in which which of earth ospheres?
Thunder, lightning, wind, and rain occur in the Earth's atmosphere.
Where does the earth emits radiation with greatest intensity at?
The Earth emits radiation with the greatest intensity in the infrared part of the spectrum, due to the thermal energy emitted by the surface. This is known as terrestrial radiation and plays a significant role in the Earth's energy balance.
Does the lunar eclipse occur when the moon is at its greatest distance from earth and the moon is new?
No on both points. The lunar eclipse can occur only at Full Moon, and has no connection with the moon's distance from earth.
Which of earth layers does radiation occur?
Radiation can occur in all layers of the Earth, but it has the greatest impact on the Earth's surface due to interactions with the atmosphere and the geomagnetic field. Cosmic radiation from space can penetrate the atmosphere and reach the Earth's surface, affecting living organisms and materials.
How soon will the comet Elein be near Earth?
the comet Elenin will be an extintion level event arriving on Aug.22-Sept.6th.

Where does earth's greatest speed of rotation occur?
The Earth's greatest speed of rotation occurs at the equator, where it moves at a speed of about 1670 kilometers per hour (1037 miles per hour) due to the larger circumference at the equator compared to the poles.
Where does the greatest atmospheric pressure occur?
It occurs in the Troposphere because it is closer to earth so the air results in being more thicker and compressed

Why is the Suffolk Punch in danger of extintion?
because it saw you.
What does mass extintion mean?
Mass extinction refers to a substantial loss of different species over a relatively short period. This event can occur due to sudden environmental changes, natural disasters, or human activities. Mass extinctions have occurred multiple times throughout Earth's history, leading to significant changes in biodiversity.
When was The Greatest Race on Earth created?
The Greatest Race on Earth was created in 2004.
When did The Greatest Race on Earth end?
The Greatest Race on Earth ended in 2009.
