Volcanoes released gases like water vapor, carbon dioxide, and sulfur dioxide during eruptions. These gases reacted with sunlight and water vapor to form oxygen molecules, contributing to the initial oxygen in the atmosphere.

What era is when earths atmosphere formed?

The Earth's atmosphere began forming approximately 4.5 billion years ago during the Hadean Eon, following the planet's formation. This initial atmosphere was likely composed of gases released from volcanic activity and impacts from comets and asteroids.


Why is the percentage of argon in the earths atmosphere today the same as it was in the earths early atmosphere?

Argon is a noble gas and does not react with other elements in the atmosphere, so it has remained relatively constant over time. The initial percentage of argon in the Earth's atmosphere was likely determined by the gases present during the planet's formation. The lack of significant processes that remove or add argon to the atmosphere has helped to maintain its percentage over time.


Would volcanic ash increase or decrease temperature in the earth's atmosphere?

Temperatures tend to fall as atmospheric particulate matter increases. This has been known from massive volcanic explosions, and a small handful of scientists some years back proposed a global thermonuclear war could potentially plunge earth into a "nuclear winter," or new ice age. We now know particulate settles out relatively quickly, so that the nuclear winter would only last 2-5 years. Both the particulate and the hydrogen sulfide gas would have an immediate cooling effect. Volcanoes also emit CO2, which lingers in the atmosphere thousands of times longer than the particulate. So although the initial effect would be cooling, the long term effect would be a slight warming. A LOT of volcanoes could build up CO2 levels significantly over thousands of years. At the present time humans release about 100 times the CO2 of all earth's volcanoes combined, according to the USGS.


What three forces below the Earth's surface influenced the Earth's creation?

Three forces that act just beneath the surface and may have spurred creation are tension, which causes the crust to pull apart or stretch. Compression, which causes the crust to squeeze and push together. Shear, which pushes, tears and forces one part of the crust past the other.


The oxygen in Earths atmosphere was released by?

The oxygen in Earth's atmosphere was released by photosynthetic organisms, such as cyanobacteria and early algae. These organisms use sunlight to convert carbon dioxide and water into oxygen as a byproduct. Over billions of years, this process helped build up the oxygen levels in the atmosphere to support aerobic life forms.

How do tidal waves form and what factors contribute to their creation?

Tidal waves, also known as tsunamis, are caused by underwater earthquakes, volcanic eruptions, or landslides that displace a large amount of water. The force of these events creates powerful waves that travel across the ocean. Factors that contribute to the formation of tidal waves include the magnitude and location of the initial disturbance, the depth of the water, and the shape of the coastline that the waves encounter.

What is the velocity of an object when it enters the atmosphere?

The velocity of an object when it enters the atmosphere can vary depending on factors such as its initial speed and angle of entry. Typically, objects entering the atmosphere from space can have velocities ranging from thousands to tens of thousands of kilometers per hour.


When nitrogen stored at 6000 psi is released into the atmosphere what is it's temperature?

When nitrogen stored at 6000 psi is released into the atmosphere, it undergoes adiabatic expansion and experiences a drop in temperature due to the decrease in pressure. The final temperature will depend on various factors like initial temperature, volume, and surroundings.


Does the c in Creation need to be capitalized?

According to the Oxford English Dictionary, when "Creation" refers "The bringing into existence of the world or the universe; the beginning of the world as an event from which time can be thought to begin," it is written "Freq. with the and capital initial." Therefore, capitalization is not strictly necessary.

A rocket ship leaves the earths atmosphere its initial velocity is less than its final velocity this is example of?

Final velocity vf is greater than the initial velocity vi . That is vf > vi . This is an example of acceleration (positive). Average acceleration aav = [vf - vi]/[tf - ti] where ti is initial time, and tf is final time.

What mechanism of the water cycle produces the smallest water droplets?

The mechanism of the water cycle that produces the smallest water droplets is condensation. As water vapor in the atmosphere cools, it transforms into tiny droplets through the process of condensation, forming clouds. These droplets can coalesce to form larger droplets, but the initial formation results in very small droplets that are essential for cloud formation. Additionally, processes like evaporation and transpiration contribute to the presence of small droplets in the atmosphere.
