Which time periods created the framework for the planet's coal beds? Cambrian and Ordovician Ordovician and Silurian Devonlan and Carboniferous Permian and Triassic

## Step 1The asking about the geological time periods that created the framework for the planet's coal beds. Coal is a fossil fuel that is formed from the remains of ancient plants and animals that lived millions of years ago. These remains were buried under layers of sediment and subjected to high pressure and temperature over time, which transformed them into coal.## Step 2The formation of coal beds is closely associated with the Carboniferous period, which occurred between 359.2 million and 299 million years ago. This period is known for its vast swamp forests, which were the primary source of the plant material that would eventually become coal.## Step 3The Devonian period, which occurred between 419.2 million and 358.9 million years ago, is also significant in the formation of coal beds. This period is known for its significant increase in plant life, which contributed to the formation of coal.## Step 4The Cambrian, Ordovician, Permian, and Triassic periods, while important in the geological history of the Earth, are not as closely associated with the formation of coal beds as the Carboniferous and Devonian periods.# Answer: The time periods that created the framework for the planet's coal beds are the Devonian and Carboniferous.
