“When volcanoes erupt, magma consists of liquid rock within the interior of the Earth. But as molten rock finds its way to the surface, we refer to it as lava. So, the main difference between magma and lava is location.” Magma and lava are both molten rock. But they exist in differ...
Jasper is formed from silica-rich sediment or volcanic ash that becomes compacted or cemented together. Over time, this process results in the formation of jasper's distinctive opaque and patterned appearance. 1 Share Your Discovery Share via Social Media Embed This Content Embed Code Share Direct...
