When the Earth was very young, volcanoes activities were intense and frequent, the continents were almost joined among themselves, the Earth surface was much hotter than today, frequent and heavy rains thunderstorms, lightning bolts hit the soil frequently, primitive animals began to form, and when they died, their decomposition started to form oxygen which began to push the ozone layer upwards. Vast forests began to grow rapidly. All above mentioned has been progressively disappearing, the continents began to change their shapes, a huge collection of animals' species started appearing and disappearing, the human being appeared 10 thousand years ago, and today we see the Earth suffering much deforestation, a lot of plants and vehicles are now releasing much carbon monoxide, and recently the global warming began to worry the governments allover the world.
What else can I help you with?
What are three ways the Earth is different today from when it was first formed?
The Earth's atmosphere has changed over time, with early Earth lacking oxygen while today it has a higher oxygen content. The planet's land mass has also shifted due to plate tectonics, leading to the formation of continents. Additionally, the Earth's surface has been shaped by erosion and weathering processes over millions of years.
What was the composition of the atmosphere when the earth was first formed?
When Earth was first formed, its atmosphere was composed mainly of hydrogen and helium, with smaller amounts of methane and ammonia. Over time, volcanic activity introduced water vapor, carbon dioxide, and nitrogen, eventually leading to the atmosphere we have today.
When did the Earth cool for the first time?
The Earth cooled for the first time around 4.5 billion years ago when it formed from a cloud of gas and dust in space. As the planet continued to cool, the surface eventually solidified to form the crust we know today.
True or False There is more water on earth today than there was when the earth was formed?
True. The water on Earth is believed to be the same water that was present when the Earth was first formed, as water is a finite resource that cycles through the environment in a process called the water cycle.
How did the earth come together in the first place?
The Earth formed around 4.5 billion years ago from a rotating disk of gas and dust in space. As gravity pulled these particles together, they collided and stuck, eventually forming the Earth we know today through a process called accretion. This process also led to the differentiation of the Earth into different layers based on density.
What do scientist believe that when the earth was first formed its crust was made of metamorphic rock?
Scientists believe that when Earth was first formed, its crust was made of molten rock that eventually cooled and solidified into igneous rock. Over time, these rocks were subjected to heat and pressure, leading to the formation of metamorphic rocks, which make up a significant portion of Earth's crust today.

Suppose that as earth formed all lighter elements were released to the surrounding space how might this disrupt the structure of earth today?
If all lighter elements were released into space as Earth formed, the planet's composition would be significantly different today. The absence of lighter elements would alter the density and chemical makeup of Earth's crust, mantle, and core, likely leading to changes in geological processes such as volcanism, tectonic plate movements, and the magnetic field. This could result in a planet with different landforms, mineral deposits, and atmospheric conditions than what we observe today.

Who discovered the Earth?
Nobody "discovered" earth, in the sense that European Explorers were said to have "discovered" The Americas and Australasia.Planet Earth formed over 4 billion years ago and life first formed about 1 billion years later.The first Human life as we understand it today originated about 200,000 years ago so it could be said that those early humans "discovered" the planet. Regrettably, there is no record of any of their names.Every being discovers Earth in a manner unique to them. In particular, the Earth known to the Birds differs from that known to the Fish, and different again from that known to most Land Animals.
How is the earth today different from back them?
There aren't dinosaurs anymore.
When was the first ever volcano?
well the earth was originally a ball of fire that cooled and formed the crust we know today, so you could say roughly 4.5 billion years ago
How is Earth today different from early earth?
in the beginning of earth it was extremely hot with very little oxygen - Jeremy ramirez
Why do you think the first generation of stars would be different from stars born today?
The first generation of stars is believed to have formed from pristine gas with fewer heavy elements compared to stars today, affecting their composition and behavior. Additionally, the first stars likely formed in different environments with higher densities and temperatures, influencing their size, mass, and lifespan. These differences may have led to the unique characteristics of the first generation stars compared to those born in the present universe.
