What is the breakdown of rock into smaller pieces by physical means?
Geology and Geographymechanical weatheringmechanical weathering, where rocks breakdown into smaller pieces by mechanical means. What is the breakdown of rocks into smaller pieces by physical forces? Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and

How many cm does the glacier move in 1 day?
Geology and GeographyGlacial motion can be fast (up to 30 metres per day (98 ft/d), observed on Jakobshavn Isbræ in Greenland) or slow (0.5 metres per year (20 in/year) on small glaciers or in the center of ice sheets), but is typically around 25 centimetres per day (9.8 in/d). How fast does a glacier move per hour?

How does surface area affect weathering?
Geology and GeographyLarge rocks have less surface area for their volume than small rocks. Therefore, a smaller portion of the rock is exposed to weathering. It takes longer for the rock to wear away. The small rock has more surface area for its vol- ume, so it weathers away faster. Does more surface area increase weathering? Surface

What type of plate boundary is formed when the plates grind past each other?
Geology and Geographytransform plate boundarytransform plate boundary occurs when two plates slide past each other, horizontally. A well-known transform plate boundary is the San Andreas Fault, which is responsible for many of California’s earthquakes. What type of plate boundary is formed when two plates grind past each other give an example of this type of boundary? Transform

What spheres interact with tsunamis?
Geology and GeographyTsunamis are giant waves in the ocean (hydrosphere), triggered by earthquakes (a primary force in the lithosphere), and have deadly consequences on coastal communities (the biosphere). How do tsunamis impact the 4 spheres? Impact on the atmosphere: Tsunamis destroy many things when they come through towns or cities, they can cause a lot of damage.

How are neritic sediments different from pelagic sediments?
Geology and GeographyNeritic sediments cover about ¼ of sea floor and are near landmasses. The term pelagic means “of or relating to the open sea” particularly the upper layers of the ocean away from shore. Pelagic sediments are generally deep-water deposits mostly oozes (see below) and windblown clays. What is the difference between neritic and pelagic deposits

What are the effects of rockfall?
Geology and GeographyRockfall causes extraordinary amounts of monetary damage and death, the former mostly by impeded transportation and commerce due to blocked highways and waterways and the latter as direct casualties from falling rocks. What is formed as a result of a rockfall? What is formed as a result of a rockfall? A talus slope. A talus

How the tectonic plates have moved?
Geology and GeographyThe plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth’s mantle and fit snugly against one another. The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other. How did the tectonic plates

Where are continental glaciers found?
Geology and GeographyWhere are Continental Glaciers Found? The big continental glaciers are mostly found in Antarctica and Greenland. The glaciers found in these places are almost 3,500 meters in thickness. Dome-shaped and circular ice caps are more significant than the ice fields but are smaller than ice sheets. Where are most continental glaciers found? Most of the

What is the texture of rock salt?
Geology and GeographyRock Salt Type Sedimentary Rock Texture Nonclastic; Fine-grained Composition Halite Color Colorless Miscellaneous Crystalline; Tastes salty; Hardness < Glass Is rock salt hard or soft? Hardness and Weight Mineralogists rate rock salt at 2 to 2.5 for hardness. This means it is quite soft, its surface able to be scratched with a fingernail. What is
