6.5 Billion years ago.
The earth is roughly 4.5 billion years old, give or take a few 'earthdays'.
Scientists hypothesize that chemical events preceded the origin of life on Earth because these events could have provided the necessary building blocks for life to form, such as organic molecules and simple compounds. By understanding how these chemicals interacted and evolved over time, scientists can gain insights into the origins of life on our planet.
Scientist theorize that a planet-sized object collided with earth and the moon formed
Scientists study deuterium in water because it can provide clues about the origin of water on Earth. Deuterium is an isotope of hydrogen that can help differentiate between water from sources like comets, asteroids, or Earth's mantle. By analyzing the deuterium content in water, scientists can determine where that water may have come from in the early stages of Earth's formation.
Which of the following describes how Eratosthenes discovered the approximate circumference of the earth
Scientists have fossil evidence supporting the idea that life originated from simple, single-celled organisms that emerged over 3.5 billion years ago. Fossils of these early microorganisms, such as cyanobacteria, provide insights into the evolution of life on Earth.
Titan, one of Saturn's moons, has a thick atmosphere and surface conditions that resemble early Earth. Scientists believe studying Titan may provide insights into how the building blocks of life formed and evolved under different conditions, potentially shedding light on the origin of life on Earth and elsewhere in the universe.
The approximate diameter of Earth is about 12,742 kilometers (7,918 miles).
The current approximate population of humans on Earth is around 7.9 billion.
