Where does green granite come from?
Regional SpecificsGreen Granite Quite a few granite quarries in Canada and Brazil feature abundant green rock formations. When blocks are cut from these geologic structures, the veining can be surprising. Verde Tortuga granite looks like the shell of a sea turtle. It is very pretty and durable due to its high quartz mineral content. What granite

Why does flowing water deposit the largest particles first?
Regional SpecificsFlowing water slows down when it reaches flatter land or flows into a body of still water. What do you think happens then? The water starts dropping the particles it was carrying. As the water slows, it drops the largest particles first. Why is the largest sediment deposited first? Larger, heavier particles like pebbles and

Can you touch Cinnabar?
Regional SpecificsIf you touch cinnabar – it’s safe. If you touch it 564 times – it’s safe. If you sleep with it for 5 months – it may be slightly dangerous. What happens if you touch cinnabar? Because of its mercury content, cinnabar can be toxic to human beings. Overexposure to mercury, mercurialism, was seen as

What do rock layers tell us about the environment?
Regional SpecificsSedimentary rocks tell us about past environments at Earth’s surface. Because of this, they are the primary story-tellers of past climate, life, and major events at Earth’s surface. Each type of environment has particular processes that occur in it that cause a particular type of sediment to be deposited there. How can a rock tell

How do you explain weathering?
Regional SpecificsWeathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. What is weathering mean

How does the theory of plate tectonics related to engineering?
Regional SpecificsEngineering Connection For construction projects, especially those near active faults and coastlines, engineers consider the effects of plate tectonics. If one tectonic plate suddenly slips with respect to another plate, the release of energy can cause earthquakes that impact structures. What is plate tectonics in civil engineering? This sliding of earth mass take place in
