Why is quick burial of an organism important to fossil formation?
GeologyThe rapid burial of remains beneath a blanket of sediment is critical to the process of fossilization because burial separates the remains from the biological and physical processes that would otherwise destroy them. Why is it important in fossil formation that organisms get buried quickly? Why are organisms that are buried rapidly more likely to
What type of volcano is mole hill?
GeologyMole Hill is a rounded hill composed of basalt, a volcanic rock, formed during the Eocene epoch of the Paleogene period. It is the eroded remnant of what was an active volcano approximately 47 million years ago, making it one of the youngest volcanoes on the east coast of North America. Is Mole Hill an
What is the biggest earthquake recorded in Los Angeles?

What was the biggest earthquake to hit Los Angeles? The Northridge quake (named after the San Fernando Valley community near
Is Colorado on a fault line?
GeologyGeologic studies indicate there are about 100 potentially active faults Colorado and more than 400 earthquake tremors of magnitude 2.5 or higher have occurred in Colorado since 1870. Movement on active faults is responsible for large earthquakes. Colorado experienced a magnitude 6.5 earthquake on November 7, 1882. Is Colorado prone to earthquakes? Each time an
What are two types of glacial drift?
GeologyGlacial drift is divided into two main types, till and stratified drift. What are the different types of glacial drift? Glacial Drift: material deposited by a glacier. Two types of drift are Till (unsorted, unstratified debris deposited directly from ice) and Stratified Drift (sorted and stratified debris deposited from glacial meltwater). What are 2 glacial
Is Ammonite an index fossil?
GeologyWith more than 10,000 species of ammonites known from the fossil record, this group is one of the most characteristic marine fossils of Cretaceous-age rocks around the world. Because they were so diverse, ammonites are considered an index fossil. What type of fossil is an ammonite? shelled cephalopods Ammonites were shelled cephalopods that died out
How igneous rocks are formed step by step?
GeologyIgneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there. How igneous rock are formed? Igneous rocks (from the
What is a normal fault?
GeologyNormal, or Dip-slip, faults are inclined fractures where the blocks have mostly shifted vertically. If the rock mass above an inclined fault moves down, the fault is termed normal, whereas if the rock above the fault moves up, the fault is termed a Reverse fault. What is a normal fault simple definition? normal fault –
What rocks are created from felsic lava and magma?
GeologyFelsic magma is viscous and does not flow easily. Most felsic magma will stay deeper in the crust and will cool to form igneous intrusive rocks such as granite and granodiorite. What type of rock is associated with lava and magma? igneous rocks The two main categories of igneous rocks are extrusive and intrusive. Extrusive
