What caused the Scablands?
Geology questionsDuring the last ice age, 18,000 to 13,000 years ago, the landscape of eastern Washington was repeatedly scoured by massive floods. They carved canyons, cut waterfalls, and sculpted a terrain of braided waterways today known as the Channeled Scablands. How was the Scablands formed? The channeled scabland was created where the Ice Age floods accelerated

How are plutonic igneous rocks formed?
Geology questionsPlutonic rocks are formed when magma cools and solidifies underground. Volcanic rocks are formed from lava that flows on the surface of the Earth and other planets and then cools and solidifies. The texture of an igneous rock depends on the size of the crystals in the rock. How are plutonic rocks formed? intrusive rock,
