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. What major cities are located near the San Andreas

Where is a collision zone?

Asked by: Lori Kahn A collision zone occurs when tectonic plates meeting at a convergent boundaryconvergent boundaryA convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined

What is meant by soft story?

Asked by: Courtney Fleming The term “soft-story” refers to one level of a building that is significantly more flexible or weak in lateral load resistance than the stories above it and the floors or the foundation below it (70% or greater reduction from one floor to the next according to the modern, International Building CodeInternational

How does a divergent plate boundary form?

Asked by: Kevin Skipper A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries. Where are divergent boundaries
