What else can I help you with?
What keeps earth the same size?
The lack of any physical mechanism to change its size significantly.
What was one way that early microbes did not change Earth?
Early microbes did not significantly change Earth's atmosphere or climate because they did not produce enough oxygen as a byproduct of their metabolism to have a large-scale impact on the environment.
Does gravity change as we move away from the earth?
No. Gravity always behaves according to the same formula, introduced by Newton.But the gravitational forces between you and the Earth certainly change when thedistance between you and the Earth's center changes significantly.
What events take place to change Earth's surface?
Earth's surface can change due to natural events like earthquakes, volcanic eruptions, and erosion. Human activities such as mining, deforestation, and construction also significantly alter the Earth's surface. Additionally, climate change can impact the Earth's surface through processes like melting glaciers and rising sea levels.
Does the mass of the Earth change?
The mass of the Earth remains relatively constant because the amount of matter on Earth does not significantly increase or decrease. However, the Earth gains a small amount of mass each year from meteorites and space dust that enter the atmosphere.
On average is the earth farther from or closer to the sun than it was 20 years ago?
The Sun's distance to Earth won't change significantly in 20 years.
How much has the earth change over time?
The Earth has changed significantly over billions of years due to geological processes such as plate tectonics, climate fluctuations, and the evolution of life forms. These changes have shaped the planet's surface, atmosphere, and ecosystems, leading to the diverse environments we see today.
If a person weighing 180 lb on Earth how much would they weigh on Venus?
A person weighing 180 lb on Earth would weigh about 170 lb on Venus. Venus has a similar gravity to Earth, so the person's weight would not change significantly.
Is titan bigger or smaller than earth?
Titan is significantly smaller than Earth.
Did the earthquake in Japan change the earths axis?
There has been a change in the shape of earth crust due to this terrible earthquake caused by displacement over Asian tectonic plates. This has resulted in 8 feet around/ over the epicentre. Such a huge change in shape of earth's crust, resulting change in earth's momentum/ GD2 around Sun; resulting our day is now shorter by fraction of micro-second!
Which natural process take the longest time to change earth's surface?
One of the slowest natural processes that change the Earth's surface is the movement of tectonic plates, which can take millions of years to significantly alter the landscape by forming mountains, valleys, and other geological features.
Do comets have the power to destroy a planet?
No. A comet can leave a large crater and, in the case of Earth, cause a mass extinction, but a comet cannot destroy a planet or even significantly change its orbit.
