What is the interaction between the atmosphere and hydrosphere?

Asked by: Malaysy Bottenhagen Plants (atmosphere) draw water (hydrosphere) and nutrients from the soil and release water vapor into the atmosphere. Plants (hydrosphere) draw water (biosphere) and nutrients from the soil and release water vapor into the atmosphere. What is the interaction between the atmosphere and biosphere? Biosphere-Atmosphere Interactions focuses on the sources and sinks

At what depth does the earth heat up?

Asked by: Ryan Mence The geothermal gradient (i.e. the increase in temperature with an increase in depth in the Earth) is not equal all over the world. On average, the temperature increases 2°- 3° C per 100 m in depth, however the increase can range from 1° to 5° C/100 m. How far into the

What’s the difference between sinkholes and subsidence?

Asked by: Adam Jaye In simplest terms, land subsidence is a lowering of the ground while sinkholes involve a collapsing of the land and usually creating a giant hole. What is the difference in collapse versus subsidence sinkholes? Karst subsidence is sinking of land that occurs as a result of gradual dissolution of soluble surface

Where are the active volcanoes in the Philippines located?

Asked by: Kara Gilbert Most of the Philippines’ active volcanoes are found on the island of Luzon, which is the largest and most prominent island in the Philippines. Aside from MayonMayonMayon is the main landmark and highest point of the province of Albay and the whole Bicol Region in the Philippines, rising 2,463 meters (8,081

Why is Earth’s surface changing?

Asked by: James Owens Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth’s plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and

What are the 4 landforms created from lava and ash?

Asked by: Heidi Johnson Landforms that form from lava and ash include shield volcanoes, cinder cone volcanoes, composite volcanoes, lava plateaus, and calderas. What types of landforms are created by lava? Landforms created by lava include volcanoes, domes, and plateaus. New land can be created by volcanic eruptions. Landforms created by magma include volcanic necks

What is the chemical property of mineral?

Asked by: Kelly Tansky What are chemical property of minerals? Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level. Color and density are determined primarily by the chemical composition.

How do you clean crystals with sea salt?

Asked by: Michele Stephens If you’re near the ocean, consider collecting a bowl of fresh saltwater. Otherwise, mix a tablespoon of sea, rock, or table salt into a bowl of water. Make sure that your stone is completely submerged, and allow it to soak for a few hours to a few days’ time. Rinse and

What happens when lava hits salt water?

Asked by: Susan Domeyer Since heat is exchanged at the interface between lava and seawater, processes that increase the surface area of lava exposed to seawater increase steam formation. High lava-flow rates produce more heated surface area. When an active bench collapses, large surfaces of hot material are suddenly exposed to seawater. What happens when

What major cities are located near the San Andreas Fault?

Asked by: Jerry Ruiz The San Andreas runs deep near and under some of California’s most populated areas. The cities of Desert Hot Springs, San Bernardino, Wrightwood, Palmdale, Gorman, Frazier Park, Daly City, Point Reyes Station and Bodega Bay rest on the San Andreas fault line.
