How has the earths atmosphere changed over millions of years?
The earth's atmosphere has changed significantly over millions of years due to various factors such as volcanic activity, changes in the Earth's orbit, and the evolution of living organisms. For example, early Earth had a different composition with high levels of carbon dioxide and little oxygen. Over time, the atmosphere changed to its current composition with nitrogen as the dominant gas and oxygen supporting life.
When Pangaea moved over earths surface what was it known as?
When Pangaea moved over Earth's surface, it was known as continental drift. This theory proposed by Alfred Wegener in 1912 suggested that the continents were once all connected as one supercontinent before drifting apart over millions of years.
What are slow changes on earths surface?
Examples of slow changes on Earth's surface include weathering of rocks over time, erosion of land by water and wind, and gradual movement of tectonic plates. These processes can take thousands to millions of years to significantly alter the Earth's surface.
What type of evidence acts as a record of changes in organisms over time and indicates major changes in earths surface and climate?
Fossils serve as evidence of changes in organisms over time and reveal major changes in the Earth's surface and climate. By studying the types of fossils found in different rock layers, scientists can understand how life has evolved and how the environment has changed over millions of years. This field of study is known as paleontology.
Why do craters last for millions of years on the surface of the moon?
Craters last for millions of years on the surface of the moon because the moon does not have an atmosphere. Saying this the moon does not have anything able to fill in the craters such as soil or rain.
What is formed from the remains of plants an animals that has been stored beneath the earths surface for millions of years?
parhaps fossils, roots, ashes or even new compost
What events always take millions of years to change the surface of the earth?
volcanoes take millions of years to occur. it changes earth's surface.
What event always takes millions of years to change the surface of the earth?
volcanoes take millions of years to occur. it changes earth's surface.
How has the earths surface changed since the beginning of earths time?
The Earth's surface has changed significantly over time due to processes such as plate tectonics, erosion, and volcanic activity. Continents have shifted positions, mountains have formed and eroded, and oceans have expanded and contracted. These changes have been ongoing for billions of years and continue to shape the Earth's surface today.
How have volcanoes changed the surface of the earth over millions of years?
The world's tectonic plates are ever changing moving by centermetres every year. This moves

How are rocks changed?
Erosion and weathering over millions of years
Which best supports the idea that the surface of the moon has changed very little?
Wow! The moon's face has changed a lot over the millions and millions of years since its birth. It is still changing as a result of getting smacked into by asteroids and other fast-moving (relatively) space debris.
Why does the earths surface look the way it does?
The Earth's surface looks the way it does because of the way the wind, water, and the tectonic plates move under the surface. They have shaped the surface into what it is today through millions of years of change.
What is most of the energy we use which formed in earths crust over hundreds of millions of years?
fossil fuels
What 2 factors have changed the earth for over millions of years?
Wind & water
