Where do earthquakes occur on a convergent plate boundary?
GeologyAbout 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on. Since neither plate is stronger than the other, they crumple and are pushed up. Where do earthquakes occur on convergent boundaries? Subduction Zones. Along convergent plate margins with

Why is it called regional metamorphism?
GeologyRegional Metamorphism. Regional metamorphism is metamorphism that occurs over broad areas of the crust. Most regionally metamorphosed rocks occur in areas that have undergone deformation during an orogenic event resulting in mountain belts that have since been eroded to expose the metamorphic rocks. How do you identify regional metamorphism? Regional metamorphism occurs when rocks are

How soil is formed short answer?
GeologySoil is formed by a process called weathering. The process of weathering occurs as a result of the action of wind, water, or climatic changes. Weathering is the process that breaks down large rocks into smaller pieces. These small pieces of rocks form soil by mixing with decaying plants and animal parts. How soil are

Is radiometric dating the same as radiocarbon dating?
GeologyIs radiometric dating and radiocarbon dating the same thing? Additional methods of radiometric dating, such as potassium-argon dating and rubidium-strontium dating, exist based on the decay of those isotopes. Radiocarbon dating is a method used to determine the age of organic material by measuring the radioactivity of its carbon content. Is radiometric dating the same

What minerals are found in evaporites?
GeologyMinerals in evaporite rocks include carbonates (especially calcite, dolomite, magnesite, and aragonite), sulfates (anhydrite and gypsum), and chlorides (particularly halite, sylvite, and carnallite), as well as various borates, silicates, nitrates, and sulfocarbonates. What are evaporites made of? Evaporite deposits are rocks composed mostly of minerals produced by evaporation of saline solutions. They range from carbonates

What is Taphonomy in anthropology?
GeologyThe term taphonomy was originally used to refer to the processes through which organic remains mineralize, also known as fossilization. Within the context of biological anthropology, the term taphonomy is better defined as the study of what happens to human remains after death. What is taphonomy in forensic anthropology? Forensic taphonomy has been defined simply

Is it better to be inside or outside in an earthquake?
GeologyIf you are inside, stay inside. DO NOT run outside or to other rooms during an earthquake. You are less likely to be injured if you stay where you are. Where is the safest place to be during an earthquake? If available, the safest place is under a strong table or desk. If no sturdy

What is lava rock made out of?
GeologyLava is made up of crystals, volcanic glass, and bubbles (volcanic gases). As magma gets closer to the surface and cools, it begins to crystallize minerals like olivine and form bubbles of volcanic gases. When lava erupts it is made up of a slush of crystals, liquid, and bubbles. What kind of rock is lava

Is limestone easy to break?
GeologyLimestone is a soft rock that is relatively easy to carve and can have a wide variety of textures. Composed of the mineral calcite, it formed on the ocean floor from sediment and the bodies of early sea creatures. … Limestone has natural bed lines that make it easier to break apart and are more
