How do you study rocks?
Regional SpecificsA knowledge of field relationships between different rock units is fundamental to the study of rocks. It is gained from mapping and observing rocks in the field. In depth analysis of rocks using a microscope or sophisticated analytical laboratory equipment provides important information on their composition. How do geologists study rocks? Rocks are made of

What evidence suggests that continents move?
Regional SpecificsThe evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones. What causes continents to move prove it with evidence? The causes of continental drift are perfectly explained by the plate tectonic theory. The earth’s outer shell is composed
How is rhyolite and granite similar?
Regional SpecificsGranite is plutonic and rhyolite is volcanic. They have very similar compositions but one is erupted onto Earth’s surface and the other crystallises at depth. As a result, plutonic rocks are coarse-grained and volcanic rocks are fine-grained. How are rhyolite and granite similar and different? Hint: Rhyolite and granite have similar composition. The difference between
Where did the word marble come from?
Geology & LandformThe word “marble” derives from the Ancient Greek μάρμαρον (mármaron), from μάρμαρος (mármaros), “crystalline rock, shining stone”, perhaps from the verb μαρμαίρω (marmaírō), “to flash, sparkle, gleam”; R.
