How do you create a geological cross section on a map?
GeologyA geological cross-section is a graphic representation of the intersection of the geological bodies in the subsurface with a vertical plane of a certain orientation. How do you draw a cross section in geography? Quote from video:We're gonna get a line draw that line all the way from A to B. Once you've got your
What country is breccia found in?
GeologyBreccia forms where broken, angular fragments of rock or mineral debris accumulate. One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates. Another is in stream deposits a short distance from the outcrop or on an alluvial fan. Where is breccia found in the
How is a limestone rock formed?
GeologyLimestone is a common sedimentary rock that is composed mostly of the mineral calcite (CaCO3). It is produced by crystallization from water, or by accumulation of shells and shell fragments. Limestone, a sedimentary rock, is made up mainly of calcite, which is made up mainly of the skeletons of microsopic organisms. How is limestone is
What are the 4 different types of fossils?
GeologyThere are four main types of fossils, all formed in a different way, which are conducive to preserving different types of organisms. These are mold fossils, cast fossils, trace fossils and true form fossils. What are 5 different types of fossils? Five different types of fossils are body fossils, molds and casts, petrification fossils, footprints
How does water move into the hydrosphere?
GeologyWater moves through the hydrosphere in a cycle. Water collects in clouds, then falls to Earth in the form of rain or snow. This water collects in rivers, lakes and oceans. Then it evaporates into the atmosphere to start the cycle all over again. How does water move from geosphere to hydrosphere? The Water Cycle

What did Wegener hypothesize happened to the continents?
GeologyIn 1912 Alfred Wegener (1880-1930) noticed the same thing and proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning “all lands”), and over time they have drifted apart into their current distribution. What did Wegener’s hypothesis happened to the continents? Alfred Wegener first presented his hypothesis to the
What type of boundary separates the South American plate from the Nazca Plate explain your answer?
Geologyconvergent boundaryconvergent boundary. What is happening at the boundary between the Nazca and South American plates? Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into the mantle in a process called
How does erosion change the earth’s surface?
GeologyThe movement of pieces of rock or soil to new locations is called erosion. Weathering and erosion can cause changes to the shape, size, and texture of different landforms (such as mountains, riverbeds, beaches, etc). Weathering and erosion can also play a role in landslides and the formation of new landforms. How does erosion affect
Is halite a fracture or cleavage?
Geologycubic cleavagecubic cleavage, and therefore, when halite crystals are broken, they will form more cubes. Octahedral cleavage occurs when there are four cleavage planes in a crystal. What type of cleavage does halite? cubic cleavage Halite (or salt) has cubic cleavage, and therefore, when halite crystals are broken, they will form more cubes. Octahedral cleavage
