At 4.5 billion years old, it can be difficult to understand just how old Earth is, and the changes that have taken place on the planet in all that time. Looking at some of its life forms, how long they lived, and when they died helps provide some scale of Earth's long existence.

The five mass extinctions in Earth’s history occurred at or near the end of the Ordovician, Devonian, Permian, Triassic and Cretaceous periods. The Ordovician extinction occurred in two phases, destroying 60 to 70 percent of all species.History. In the early 20th century, geologists such as Bernard Brunhes first noticed that some volcanic rocks were magnetized opposite to the direction of the local Earth's field. The first systematic evidence for and time-scale estimate of the magnetic reversals were made by Motonori Matuyama in the late 1920s; he observed that rocks with reversed fields …

You might wish to start in the Cenozoic Era (65.5 million years ago to the present) and work back through time, or start with Hadean time (4.6 to 4 billion years ago)* and journey ...At least five major ice ages have occurred throughout Earth’s history: the earliest was over 2 billion years ago, and the most recent one began approximately 3 million years ago and continues today (yes, we live in an ice age!). Currently, we are in a warm interglacial that began about 11,000 years ago.

Climate is the long-term pattern of weather in a particular area. Weather can change from hour to hour, day to day, month to month or even from year to year. For periods of 30 years or more, however, distinct weather patterns occur. A desert might experience a rainy week, but over the long term, the region receives very little rainfall.

A history-of-Earth timeline includes everything from the birth of the sun and solar system to present-day earthquakes in California. Changes over the past 4.6 billion years were usually slow and incremental, but also sometimes violent and unforeseen, like giant meteorite strikes.

BBC Verify is analysing evidence from the Al-Ahli hospital explosion amid competing claims over responsibility.In 1862, the physicist William Thomson, 1st Baron Kelvin published calculations that fixed the age of Earth at between 20 million and 400 million years. He assumed that Earth had formed as a completely molten object, and determined the amount of time it would take for the near-surface temperature gradient to decrease to its present value.

The development of life over the last 3,700 million years of the Earth's history is one of the great stories told by modern science.

The geologic history of Earth's Moon has been divided into a time scale based on geomorphological markers, namely impact cratering, volcanism, and erosion. This process of dividing the Moon's history in this manner means that the time scale boundaries do not imply fundamental changes in geological processes, unlike Earth's geologic time scale.
