What island was formed from an undersea volcano?
Thousands of islands have been formed by undersea volcanoes including the Hawaiian Islands, the Galapagos, many of the western Antilles, the Aleutian Islands, the Philippines, the South Sandwich Islands, the Canary Islands, the Azores, the Marianas, and many others.
What are 4 changes which extrusive volcanic features undergo?
Extrusive volcanic features undergo several changes over time, including erosion, which gradually wears down volcanic structures like lava flows and ash deposits. Weathering can alter the composition and stability of volcanic rocks, leading to their breakdown. Additionally, cooling and solidification of lava can result in the formation of new mineral structures. Lastly, vegetation can gradually colonize volcanic landscapes, transforming them into ecosystems and changing their appearance and ecological function.
What are 4 materials that fossils can be found in?
amber, petrified fossils, trace fossils, carbon films, molds, and cast.
Is anhydrite harder than limestone?
Yes, anhydrite is generally harder than limestone. Anhydrite, which is composed primarily of calcium sulfate, typically has a hardness of around 3 to 3.5 on the Mohs scale, while limestone, primarily composed of calcium carbonate, has a hardness of about 3 to 4. However, the hardness can vary depending on the specific type of limestone and its mineral content. Overall, anhydrite is considered to be more resistant to abrasion compared to limestone.
How much limestone is quarried each year?
on average 3-4 million tonnes of limestone is quarried each year.
