Ozone is concentrated at 20-40 km above earth with highest concentration 6-8 parts per million. It is present in the stratosphere of the earth's atmosphere.
100% of the scandium found is found on Earth. But that's not the answer you wanted. What you wanted was the answer to the questions "what percentage of the earth is scandium?" The Clarke Number is variously given as in the 20 to 24 range. This means that out of each million parts of the Earth's crust (we must use only the crust as we can't really measure what the centre of the Earth is made of) 20 parts to 24 parts are scandium.
The oldest fossils found are considered to be from the late Archean period which ended 2500 million years ago. By contrast, the Earth is believed to be 4500 million years old. So, though both dates are amazingly old, the Earth is definitely older than the fossils.
100% of Earth's rivers are found on Earth.
The element neon is found in advertising signs,high voltage indicators, lightning arrestors, wave meter tubes, TV tubes, gas lasers, economical cryogenic refridgerant, and Glow Sticks. Neon in the Native state, is found mostly in the atmosphere and rocks in the crust of earth. It is more likely to be found outside of Earth.

The landmass found to the south of the Philippines is Borneo, which is the third-largest island in the world. Borneo is shared by three countries: Indonesia, Malaysia, and Brunei.
Earth was too hot to have solid rocks at that time.

The concentration of Helium on Earth is approx 1 part in 10 million = 0.00001%
Mountains are mainly found in areas with geological processes like plate tectonics, where tectonic plates collide or move apart, causing the Earth's crust to rise and form mountains. They can be found on every continent and make up a significant portion of the Earth's landmass.

Alfred Wegner thought that all the continents used to be one giant landmass called Pangea. He said that the continents would move a little each year. The scientists didnt believe him though, but later found out that it could be true because of the plates in the earth
