Very different.
New mountain ranges, new canyons, hardly any oceans, hardly any life.
The shape of the continents will be visible (but they will be different from how we know them now).
The atmosphere will be very humid due to water vapor.
You would need protection to look at the Earth's surface because the sun has become much brighter.
The moon will appear much smaller because it is further away.
- Within 50 million years, the African plate will move further north and collide with Europe, causing the Mediterranean Sea to disappear; a new large mountain range will form, similar to the Himalayas, with mountains possibly larger than Mount Everest.
- Within 250 million years, all continents will come back together to form one supercontinent like Pangea.
- Within 500–600 million years, a gamma-ray burst (this is intense gamma radiation) will likely occur 6,500 light years away from us, but will be able to reach our galaxy, and thus Earth as well.
This will severely damage the ozone layer, with the result that a very large part of life on Earth will no longer be able to survive. - In the meantime, our sun is becoming brighter and brighter.
- Plate tectonics is also expected to cease within 600 million years (meaning the landmasses will no longer move).
As a result, the natural carbon cycle will come to a standstill, and CO2 levels will drop drastically, making plant photosynthesis impossible. Many C3 plants, such as deciduous trees, will die.
C3 photosynthesis will no longer be possible, and 99% of plants may have died.
(Most sources agree with this). - Within 800 million years, CO2 levels will have dropped to such an extent that C4 photosynthesis is no longer possible. C4 plants like corn will die off (or at least what is left of them).
Oxygen gas and ozone will be gone, and virtually all complex life on Earth will die out. - When we are 1 billion years from now:
The sun will shine 10% brighter, and the average temperature could be 47°C (according to various sources).
The oceans will slowly evaporate.
Water may only remain in the polar regions, and therefore the very last complex life will be found in those areas.
