The History Of The Earth From Formation To Present Day

Earth formed approximately 4.54 billion years ago and was mostly completed within 10–20 million years.

In 4.4 billion years ago, our planet's first oceans formed. Water vapor was freed into the Earth's atmosphere by volcanism. It then cooled, dropped back down as precipitation, and created the planet's first oceans. Some water has additionally been delivered to Earth by asteroids and comets.

3.85 billion years ago, the first life emerged on the planet.

Between 2.1 billion and 2.03 billion years ago, the increase of oxygen began rapidly, and the present situation was reached 1.5 billion years ago. Cyanobacteria make oxygen a product of photosynthesis.

700 million years ago, the first simple single-celled animals evolved.

530 million years ago, the first vertebrates in the ocean (fish) appeared on the planet.

400 million years ago, the first land plants developed. Oxygen in the atmosphere acted to form ozone, which created a layer. The ozone layer functioned as a protecting barrier to the dangerous rays coming from space, supporting plants to colonize the land.

350 million years ago, the first land vertebrates emerged. With plants being on the land to give a food source, animals quickly followed. The first to attempt onto the land was first amphibians, and reptiles emerged shortly after.

225 million years ago, the first dinosaurs developed from reptiles.

65 million years ago, the dinosaurs and many other species were gone by the after-effects of a meteorite collision. The impact set off a series of earthquakes, volcanic explosions, and tsunamis, which threw lots of dust particles and acid into the atmosphere, causing an impact winter. The dust impeded out the sunshine so plants could no longer photosynthesize, and food chains were destroyed. After the extinction of the dinosaurs, mammals developed quickly and filled the evolutionary niches they left behind.

130 thousand ago, modern humans developed. Homo sapiens emerged in the African continent from the first humans. They left Africa about 35 thousand years ago and spread worldwide.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

How Cold Can It Get? The Lowest Temperatures Ever Recorded, Mapped

We often talk about record heat , especially in the context of climate change. But on the flip side, our planet also experiences cold so extreme it defies belief—temperatures that can flash-freeze exposed skin and halt life as we know it. These are not just numbers on thermometers; they’re snapshots of how Earth's atmosphere behaves under specific conditions—altitude, wind patterns, and location far from the moderating effects of oceans. The coldest temperature ever recorded on Earth? That title goes to Vostok Station in Antarctica, where scientists measured a bone-cracking −89.2°C (−128.6°F) on July 21, 1983. Located on the East Antarctic Plateau, Vostok is more than 1,000 kilometers from the South Pole and sits atop about 3.7 kilometers (2.3 miles) of ice. It’s isolated, dry, and high—three ingredients that make for perfect deep freeze conditions. The world map below created by VividMaps shows the lowest temperature ever recorded by country.

Mapping the Hottest Temperatures Ever Recorded on Earth

When summer arrives, it brings not only vacation season but also some of the most extreme heat waves across the globe. While many people associate summer with warm, sunny days, some regions endure scorching temperatures that push the limits of human endurance. To put these extremes into perspective, we’ve mapped the highest temperatures ever recorded in countries around the world. The maps below, created by Vivid Maps , illustrate these record-breaking temperatures and the patterns of extreme heat across the globe. The Hottest Temperature on Record According to historical weather data, the highest reliably recorded temperature on Earth is 56.7°C (134°F) , measured in Death Valley, California , on July 10, 1913 . However, an even higher temperature of 58°C (136.4°F) was reportedly recorded in El Azizia, Libya , on September 13, 1922 . While this Libyan record stood for decades, some meteorologists have questioned its accuracy due to inconsistencies in measurement methods at the ti...
