Water is life, falling on the ground, percolating into it, into the cracks between the pavement. Water finds its way through layers of rock and can appear thousands of years later in a spring. Water covers two thirds of the world in oceans and seas. But it is only a thin coat. Most of the world is molten or an iron core, with a mantle of rock floating above. Volcanos erupt around the world, Hawaii is a chain of volcanic islands erupting like a chain of bubbles in the Pacific ocean.
Are there other ‘water worlds’? Maybe Europa, a moon of Jupiter, which is covered in ice, could have oceans of water under its frozen crust.
As we came out of choir group tonight it was cold and icy. The snow that had fallen earlier had turned from slush on the car park to hard ridges and furrows and ice.
