How does groundwater cause caves to form?
GeologyWorking slowly over many years, ground water travels along small cracks. The water dissolves and carries away the solid rock gradually enlarging the cracks, eventually forming a cave. Ground water carries the dissolved minerals in solution. The minerals may then be deposited, for example, as stalagmites or stalactites. How does groundwater cause landforms? Groundwater creates
What is the jigsaw fit theory?
GeologyThe east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle, and Wegener discovered their rock layers “fit” just as clearly. South America and Africa were not the only continents with similar geology. Who gave jigsaw fit theory? A Wegener The jigsaw fit, one
How long for a tsunami after an earthquake?
Geology questionsAs the estimated time of the tsunami waves to reach the coast is 30 minutes after the earthquake, the community should go to the vertical or horizontal evacuation in less than 30 minutes. In an evacuation, the city frequently does the evacuation after obtaining official directions from the authorities. Does a tsunami happen after an

What metamorphic rocks form from basalt?
GeologySlate (metamorphic) if put under more pressure could change into a schist. A basalt (igneous) could also become a schist. Limestone (sedimentary) can become marble. Metamorphic rocks record how temperature and pressure affected an area when it was forming. Can basalt turn into metamorphic rock? Intense heat or great pressure transforms basalt into its metamorphic
How are fossils preserved?
GeologyFossils are preserved by three main methods: unaltered soft or hard parts, altered hard parts, and trace fossils. You already learned about trace fossils in Chapter 4. Unaltered fossils are rare except as captured in amber, trapped in tar, dried out, or frozen as a preserved wooly mammoth. What are 5 ways fossils are preserved?
What are minerals give two examples?
GeologyA mineral is a pure substance with a specific composition and structure, while a rock is typically a mixture of several different minerals (although a few types of rock may include only one type of mineral). Examples of minerals are feldspar, quartz, mica, halite, calcite, and amphibole. What are minerals give examples? A mineral is
Can you use lava rock for drainage?
GeologyLava rocks are the ultimate drainage solution for your plant babies to prevent a heavy-handed watering. If you have an indoor planter without a drainage hole, placing lava rocks at the bottom of the planter can help prevent drowning your plants by creating a place for excess water to pool. What can lava rock be
How are columns formed in caves?
GeologyCave columns occur when stalactites and stalagmites fuse together. This column then grew a series of cave formations, or speleothems, known as “cave popcorn.” How do cave formations form? Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into
What caused the biggest tsunami?
GeologyHowever, it should be noted, that the largest tsunami wave ever observed anywhere in the world was caused by a rock fall in Lituya Bay, Alaska on July 10, 1958. What was the largest tsunami caused by? The highest, reliably measured tsunami on record occurred in Lituya Bay, Alaska on 9 July 1958. This was
