Stratus.
Techinally the kind of cloud that spreads over the the sky in layers is the cumulonimbus cloud, but the cumulonimbus cloud spreads out in THICK layers over the sky. The question would be if the cumulonimbus cloud really does spread over the sky in layers.
Nimbostratus clouds produce drizzle. These are low, thick layers of clouds associated with steady rain or snow. Drizzle is typically light precipitation that falls from these clouds.
Cirrostratus clouds are wispy, thin sheets of ice crystals found spreading at high elevations. These clouds are typically located above 20,000 feet and are associated with upcoming weather changes.
Wel there is a simple answer. Stratus clouds are clouds that have layers or smooth even sheets in the sky. Kind of like a chesseburger where ou have a bun lettus tomato hamburger chesse and then a pickle and another bun.
