The sun is made up of mostly hydrogen and helium, making it a gaseous ball of plasma.
Why does the stratosphere end at 9 miles?
The stratosphere does not have a definitive upper boundary, but it generally extends up to about 31 miles above the Earth's surface. The 9-mile mark you might be referring to is where the troposphere transitions into the stratosphere, known as the tropopause, due to changes in temperature and other atmospheric properties.
What is the Yukatan peninsula mostly made of?
The Yucatan Peninsula is mostly made of limestone bedrock, which is porous and can dissolve easily in water. This geology has led to the formation of underground rivers, sinkholes (cenotes), and a unique landscape in the region.
What is the percentage of gases in the stratosphere?
The stratosphere is composed mostly of nitrogen (about 78%) and oxygen (about 21%). Other gases present in smaller amounts include ozone, water vapor, and trace gases like helium and methane. The exact percentages can vary slightly depending on altitude and location.
