Is soil a product of weathering?
Regional SpecificsSoils develop because of the weathering of materials on Earth’s surface, including the mechanical breakup of rocks, and the chemical weathering of minerals. Soil development is facilitated by the downward percolation of water. Is soil a weathering? Weathering describes the means by which soil, rocks and minerals are changed by physical and chemical processes into

Which mass wasting process has the slowest rate of movement?
Regional SpecificsSoil creep is a slow and long term mass movement. What is the slowest type of mass movement process? Creep is the slowest of all the mass movements and moves the most soil out of all the mass movements. What type of mass movement is the slowest fastest? Mass movements differ from one another based

What are the three ways that form ores?
Regional SpecificsThere are three major types of ore genesis: internal processes, hydrothermal processes, and surficial processes. Ore can accumulate through geologic activity, such as when volcanoes bring ore from deep in the planet to the surface. This is called an internal process. How are ores formed? Deposits of minerals form when a medium that contains and

Where are deep ocean trenches found?
Regional SpecificsTrenches are found on the floor of the sea; however, their common name is deep ocean trenches because they are more often found in the deepest areas of the ocean. Trenches are formed in subduction zones where tectonic plates collide. There are many known trenches that scientists continue to study. Where are deep ocean trenches

What evidence exists for active volcanoes on Venus?
Regional SpecificsEvidence of a warm interior and geologic activity dots the surface of the planet in the form of ring-like structures known as coronae, which form when plumes of hot material deep inside the planet rise through the mantle layer and crust. This is similar to the way mantle plumes formed the volcanic Hawaiian Islands. Is

Why do rocks break down?
Regional SpecificsThe water in the cracks freezes as the temperature drops below freezing. As the water freezes, it expands. This expansion exerts tremendous pressure on the surrounding rock and acts like a wedge, making cracks wider. After repeated freezing and thawing of water, the rock breaks apart. What causes rocks to break down? Water, ice, acids,
