Lava is the molten rock expelled by a volcano during an eruption and the resulting rock after solidification and cooling. This molten rock is formed in the interior of some planets, including Earth, and some of their satellites.The source of the heat that melts the rock within the earth is geothermal energy.When first erupted from a volcanic vent, lava is a liquid at temperatures from 700 to 1,200 Â°C (1,292 to 2,192 Â°F).his molten rock is formed in the interior of some planets, including Earth, and some of their satellites.

8. Learn how to pick a nylon anchor line. The chain, rope, or combination of these that attaches the anchor to your boat is called an anchor rode. Nylon's elasticity allows it to respond well to sudden wind and current changes, and a high quality rope is sufficiently strong to use as a rode. In rough circumstances, you may need to use one anchor at the bow and a second anchor at the stern. 2  Only do this if nearby boats are using this method, as boats using one or two anchors swing by different amounts and easily foul each other's lines.
