What is plate tectonics? Earthquakes and volcanoes

By |2018-04-18T09:54:07+00:00September 21st, 2017|Geology|

The world as seen from space (flattened out) When you look at a map of the world, it seems as though it was always like that - North America on top of South America, Europe north of Africa, Australia off at the bottom right. But really all of the dry land on Earth moves around like floating shapes about 60 miles [...]

What is snow? Weather – Earth science

By |2018-04-24T14:32:37+00:00August 20th, 2017|Physics|

If it's colder, rain may fall as snow. About two and a half billion years ago, the Earth finally cooled down enough for it to snow for the first time. Most of the time since then, the Earth has been warm enough that it didn't snow at all. But from time to time, the Earth becomes cooler, entering [...]

Earthquakes and algae – the planet Earth

Molten lava Most of the molecules that smashed together to make the Earth were iron. The smashing together released a lot of heat, so the whole center of the Earth is made of hot melted iron. Because iron is heavier than most other metals, it sank to the center of the Earth. Lighter molecules like silicon and [...]

Shiva – Hindu god – Ancient India

The Hindu god Shiva Shiva was a Hindu fertility god, who made the crops grow. He was not mentioned in the Rig Veda, about 1000 BC, and seems to have come into Hinduism later than that. Around 300 BC, in the Mauryan period, people began worshipping Shiva. This might be another name for the Harappan god Rudra. But unlike the earlier Hindu gods, [...]

Indian woman from the Mauryan period (ca. 200 BC) This story comes from the Sanskrit epic poem the Mahabharata. Story-tellers were probably telling this story at least by 500 BC, during the Vedic period, and somebody wrote it down by 300 BC or so. This is the earliest version of the Cinderella story that anybody knows. In this story, [...]

Ancient Indian environment

Indian Monsoon In much of India, there was only one big weather event every year, and that was the monsoon. Most of the year, it was very dry and sunny in India. Everything got hot and dusty and brown. But around May, clouds would start to gather, and it would get very muggy and heavy-feeling, and everybody would feel [...]

Where are the Himalaya Mountains? India

By |2018-04-21T11:56:45+00:00June 25th, 2017|China, Geology, India|

Himalaya Mountains About 55 million years ago, plate tectonics made the land that is now India break off from what is now Africa. At this time, the first modern mammals like rats and guinea pigs were evolving, and most of the Earth was covered in forests. For five million years India floated slowly [...]

Up in the Alps in Switzerland Which mountains are the highest in the world? Practice graphing and see how much higher some mountain chains are than others. The highest peaks of each mountain range are below: Appalachian Mountains: 2037 meters above sea level Alps: 4810 meters Rocky Mountains: 4399 meters Himalaya Mountains: 8850 [...]

Tertiary period: Large animals evolved like moose Dinosaurs become extinct The Tertiary period begins with the catastrophe that killed off the dinosaurs at the end of the Cretaceous Period, about 65 million years ago. And the Tertiary lasts down to 1.8 million years ago. Mammals become more common With nearly all of the dinosaurs [...]

Himalaya Mountains Sometimes people describe China's landscape as being like a staircase with three steps. The top step of this staircase is in the west, where the Himalaya mountains are (India is on the other side of these mountains). Tibet is in this part of China. People call it "the roof of the [...]
