Earth and Mountains

There are many mountains in the world, and they are found on every continent. Mountain ranges such as the Himalayas, the Andes, the Rockies, the Alps, and the Himalayas comprise numerous peaks and valleys. Additionally, new mountains can be formed through geological processes like tectonic activity, and erosion can also change landscapes over time. The exact number of mountains can vary based on definitions and classifications, but it is understood that there are countless individual mountains worldwide.  Mountains play a significant role in shaping the Earth's surface and influencing its geological and environmental processes, but they don’t directly "keep" the Earth in a specific form. Here are a few ways mountains contribute to the Earth's landscape: 1. Tectonic Activity: Mountains are often  While mountains are crucial to the Earth's geological and biological systems, the Earth's "form" is determined by a combination of various factor...

New water cycle on Mars discovered

Approximately every two Earth years, when it is summer on the southern hemisphere of Mars, a window opens: Only in this season can water vapor efficiently rise from the lower into the upper Martian atmosphere. There, winds carry the rare gas to the north pole. While part of the water vapor decays and escapes into space, the rest sinks back down near the poles. Researchers from the Moscow Institute of Physics and Technology and the Max Planck Institute for Solar System Research (MPS) in Germany describe this unusual Martian water cycle in a current issue of the Geophysical Research Letters. Their computer simulations show how water vapor overcomes the barrier of cold air in the middle atmosphere of Mars and reaches higher atmospheric layers. This could explain why Mars, unlike Earth, has lost most of its water.
