Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.

How humans change the atmosphere of the planet in the past 200 years?
They have increased the levels of greenhouse gases.
Were there earthquakes before humans were on earth?
Humans have walked the earth for the last 50 - 200K years. There have been earthquakes since the formation of the planet ~4.5 billions years ago - long before humans were around.
If scientists found a new planet outside our solar system that had an atmosphere similar to Earth's three billion years ago what kingdom's organisms would you expect the new planet's organisms to re?
Archaebacteria
Does Mars atmosphere change from season to season?
Yes, Mars' atmosphere does change from season to season. During the planet's winter, carbon dioxide freezes out of the atmosphere, causing it to thin. In summer, this carbon dioxide sublimes back into the atmosphere, thickening it again.
When first discoveed the planet earth?
Earth's exact age is indefinite but it is millions of years old. Humans discovered it when they had their first concious thought.

What are the chances of the Earth ending within 50 years?
Pretty high if humans keep on polluting the earth and causing the atmosphere to thin out, allowing dangerous radiation into out planet.
How long have humans been on the planet?
Modern humans have been around for 200,000 years.

When did the earth first develop an atmosphere and oceans?
The Earth's atmosphere first developed around 4.5 billion years ago when the planet formed. Oceans began to form around 4 billion years ago as water vapor in the atmosphere condensed and fell as rain, filling the low-lying areas of the planet.
How have humans changed the atmosphere of the plants in the past 200 years?
Humans have significantly altered the Earth's atmosphere in the past 200 years by increasing the concentration of greenhouse gases, primarily carbon dioxide, through activities like burning fossil fuels and deforestation. This has led to global warming and climate change, impacting weather patterns, sea levels, and ecosystems worldwide.
Were there earthquakes before humans were on earth?
Humans have walked the earth for the last 50 - 200K years. There have been earthquakes since the formation of the planet ~4.5 billions years ago - long before humans were around.
How has the atmosphere changed over the last 4.5 billion years?
Due to photosynthesising, single celled organisms, the atmosphere now has much more oxygen in it. this is possibly the most important change as with out we would exist. The atmosphere originally had much more carbon-dioxide and made the planet so hot humans would not be able to survive.
