How old is the earth?

Whichever theory is right, astronomers have figured out that it all probably happened about 5,500,000,000 years old! But other scientists besides astronomer have tackled this question. They tried to find the answer by studying how long it took for the earth to become the way we know it. They studied the length of time it takes to wear down to the oldest mountains, or the time needed for the oceans to collect the salt they now contain. After all their studies, these scientists agree with the astronomer: the earth is about 5,500,000,000 years old.

The Mountains

In the world, there are many things around us and just some of it that we know what is it and how was it made? but there are some simple things that we know and can see them every day, and we are not interset on how they came formed and how was it made? just like the Earth, Ocean, Rainy, Mining, Desert, and Mountain. 

Have You Ever Wondered...

How are mountains made?
Are mountains still being formed?

The humongous oceans and dense forests to sweeping plains and rolling hills, nature paint a vivid picture that can take your best breath away.

Maybe one of the most incredible sights on Earth, though, is a majestic mountain range. From the Himalayas to the Rocky Mountains, there's just something about those tall, craggy peaks that stirs the soul. 

Have you ever wondered how mountains got there, though? Did they fall out of the sky and land where they are?

There are several different ways that mountains can form. One thing these methods have in common is that they all take millions of years or less than.

Many mountains were formed as a result of Earth's tectonic plates smashing together. The Earth's crust is made up of multiple tectonic plates that still move today as a result of geologic activity below the surface.

When two tectonic plates converge, their edges can crumple kind of like an aluminum can do when you crush it. The result of these tectonic plates crumpling is huge slabs of rock being pushed up into the air. What are those called? They are Mountains.

For example, the tectonic plates that lie underneath India and Asia crashed into each other over 25 million years ago. And what happened? The Himalayas, including Mount Everest, were formed. And they're still pushing against each other. That means the Himalayas continue to grow even today!

Mountains can also form along natural fault lines. These are places in Earth's crust where tectonic plates grind against each other. Occasionally, two plates will grind together, resulting in one plate lifting up and tilting over. The result? A mountain range, like the Sierra Nevada mountain range in California.

One other way mountain form is the result of volcanic activity below the Earth's surface. Sometimes molten rock called magma gets pushed up toward the surface. When that happens, it cools and forms hard rock. Eventually, the softer rock above it erodes to reveal a dome-shaped mountain below. If the magma actually breaks through to the surface, we will get a volcano! 

In an area with a high plateau, rivers and streams can carve away stone in the form of deep channels. Over millions of years, what is left is a mountain between deep river valleys!

Volcanoes

A volcano on Earth is a vent or fissure in the planet's crust through which lava, ash, rock, and gases erupt. A volcano is also a mountain formed by the accumulation of these eruptive products. Volcanoes are Earth's geologic architects. They've created more than 80 percent of our planet's surface, laying the foundation that has allowed life to thrive. Their explosive force crafts mountains as well as craters.

Volcanoes have existed for a long time on Earth, likely causing disasters such as the Permian mass extinction about 250 million years ago, the greatest mass extinction in Earth's history, according to a 2015 paper. Volcanoes can and have existed on other worlds as well: although volcanoes on the moon and Mars have long been dormant, volcanoes are still very active on Jupiter's moon Io.

There are some reasons how was the volcano came formed!!!

Earth's crust is 3 to 37 miles thick, according to the U.S. Geological Survey. It is broken up into seven major and 152 smaller pieces called tectonic plates, according to a 2016 paper by Christopher Harrison at the University of Miami. These plates float on a layer of magma, semi-liquid rock, and dissolved gases. At the boundaries of these places, where they move past, are pushed under, or move away from each other, magma, which is lighter than the surrounding solid rock, is often able to force its way up through cracks and fissures. Magma can explode from the vent, or it can flow out of the volcano-like an overflowing cup. Magma that has erupted is called lava.

There are volcanoes on every continent, even Antarctica. Some 1,500 volcanoes are still considered potentially active around the world today; 161 of those over 10 percent sit within the boundaries of the United States. But each volcano is different. Some burst to life in explosive eruptions, like the 1991 eruption of Mount Pinatubo, and others burp rivers of lava in what's known as an effusive eruption, like the 2018 activity of Hawaii's Kilauea volcano. These differences are all thanks to the chemistry driving the molten activity. Effusive eruptions are more common when the magma is less viscous, or runny, which allows gas to escape and the magma to flow down the volcano's slopes.

Top 10 Highest Mountains In The World

Most people already know that the world’s highest mountain is Mount Everest. It’s common knowledge, it’s mainstream, it’s not much of a secret. But, and let’s get real for a second, how many people do you think they know what each the world’s highest mountain is?

10) Annapurna Massif (In Nepal) 

Annapurna that we’re in fact referring to the only mountain in the massif with an elevation above 8,000 meters (8,091m). Historically speaking Annapurna, and the supporting peaks in the massif, are some of the world’s most difficult and dangerous mountains to climb. The fatality-to-summit ratio on Annapurna, for example, is a truly terrifying 32%. The mountain is located in north-central Nepal.

9) Nanga Parbat (Mountain in Asia)

The summit is 8,126 meters above sea level - So, Nanga Parbat is the ninth highest mountain in the world. The mountain is situated in the Gilgit-Baltistan region of Pakistan. It resides at the westernmost point of the Himalayas and is also the furthest west of all the world’s eight thousand meter peaks. Nanga Parbat is a notoriously dangerous hill to climb and has been labeled the “Killer Mountain” by those who deal in nicknames and the like. Locally speaking, the mountain is known as Deo Mir. Translated literally, this means “Huge Mountain.”

 

8) Manaslu (Mountain in Nepal)

  Now, let's see what is number eight? It's Mount Manaslu. Manaslu can be found in the west-central part of Nepal and has a summit that’s situated 8,163m above sea level. The first successful ascent of Manaslu occurred in 1956 when Japanese climber Toshio Imanishi and Nepalese Sherpa Gyalzen Norbu made it to the summit. 

 

7) Dhaulagiri (Mountain in Nepal) 

With an elevation of 8,167 meters, Dhaulagiri is the seventh highest mountain in the world. It’s located in Nepal and was first summited in 1960. In 1808, Dhaulagiri was marked down in the record books as the world’s highest mountain of those yet surveyed.

6) Cho Oyu (Mountain in Nepal & China-Tibet)

Coming in at number six on the list of the all-time highest mountains is Cho Oyu. While it’s anything but a casual walk in the park, its elevation is an intimidating 8,188 meters, after all, Cho Oyu is seen by many to be the “easiest” of the plus-8,000m mountains to climb due to its accessibility and generally moderate slopes. Cho Oyo, which means “Turquoise Goddess”, stands on the Chinese-Nepalese border.

 

5) Makalu (Mountain in Asia)

With an elevation of 8,485m, Makalu is officially the fifth highest mountain in the world. Situated 19km southeast of Everest, on the border between Nepal and China, Makalu is notable for its summit’s iconic pyramid shape. Makalu was first summited in 1955. Makalu is viewed by many in the mountaineering community as one of the world’s most difficult climbs. The latter stages of the ascent, in particular, involve some extremely technical rock and ice climbing.

 

4) Lhotse (Mountain in Asia)

Lhotse, elevation 8,516 meters, is the fourth highest mountain in the world. It neighbors Mount Everest and forms part of the Everest massif. The summit of Lhotse is on the border between the Khumbu region of Nepal and Tibet. It was first climbed to in 1956 when a Swiss team made up. The Lhotse is widely considered to be the most difficult climb over eight thousand meters in the world. This is, in large part, because of the intimidating tower-like shape on its upper reaches.

 

3) Kangchenjunga (Mountain in Asia)

Perhaps more importantly than that, the third highest mountain in the world. It sits on the border between Nepal and India and has an elevation of 8,586 meters. There is a tradition when ascending Kangchenjunga to stop just short of the summit. This dates back to the first successful climb of the mountain by Joe Brown and George Brand in 1955. Every climber since then has followed the respectful example set by the first ascent.

 

2) K2 (Mountain in Asia)

K2, also known officially as Mount Godwin-Austen or Chhogori, has a summit of 8,611 meters above sea level. It is located on the border between China and Pakistan. The Chinese side of the mountain is widely considered to be the more difficult and hazardous side, so the summit is usually attempted from the Pakistan side. Behind Annapurna, K2 has the second-highest fatality rate of any mountain with a height of over 8,000 meters. Unlike with the other 8,000 meter peaks, nobody has ever successfully ascended K2 in winter.

 

1) Mount Everest (Mountain in Asia)

As we’ve already said, and as you already knew, Mount Everest is the world’s highest mountain. Its peak is an eye-watering 8,848 meters above sea level, making it well over eight times taller than the highest mountain in Wales. Everest is situated on the border between Nepal and the autonomous region of Tibet. Officially speaking, the first successful Everest climbers were Sir Edmund Hillary and Tenzing Norgay in 1953. It is estimated that there are well over 200 dead bodies on Everest, all of them remarkably well-preserved because of the extremely cold temperatures.
