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...

The 'special relationship' between supermassive black holes (SMBHs) and their hosts -- something astronomers and physicists have observed for quite a while -- can now be understood as a bond that begins early in a galaxy's formation and has a say in how both the galaxy and the SMBH at its center grow over time, according to a new study.
