What is a type of opening along which weathering agents attack bedrock?
They could be joints, fissures, cracks, or faults.
What is the name for tree roots forming out of rocks?
Biological weathering; Its a type of weathering which involves the breaking apart and disintegration of rocks throught the process of tree roots out growth or development by opening of cracks, joints and faults in rocks.
Where are mountains belts form?
Mountains are most often formed on faults. Because these faults occur due to the space between tectonic plates, these faults take the form of lines. Thus, the thin belts are along these long lines.
Are the three types of faults normal faults backward faults and slip faults?
No. Your terminology is close but not quite right. The three main types of faults are normal faults, reverse faults, and strike-slip faults. Strike-slip faults may also be called transform faults.
What factors determine the rate of weathering?
* Climate- Climate, which is usually measured in terms of temperature and moisture, can drastically affect the rate of weathering. High amounts of water and higher temperatures generally cause chemical reactions to run faster. Thus warm humid climates generally have more highly weathered rock, and rates of weathering are higher than in cold dry climates. Example: limestones in a dry desert climate are very resistant to weathering, but limestones in a tropical climate weather very rapidly. A high temperature and high amounts of water also controls vegetation which indirectly affects rate. Seasonality of precipitation affects rate to a degree. · Organisms (Biota) Animals- burrowing organisms like rodents, earthworms, & ants, bring material to the surface were it can be exposed to the agents of weathering.* Time- Weathering is a slow process. When we speak of time in a geologic sense, millions of years are often used as the units. The bedrock of Greenland has barely been weathered, and its age is over 3.5 billion years. The longer that a rock has been exposed to the weather, the faster it weathers. * Mineral Composition- All chemical and physical properties are determined by the mineral composition of the rock. Mineral composition is more important in determining the rate of chemical weathering. Those minerals that are most reactive with acids, water, and air are weathered at a more rapid rate. Mineral composition also affects physical weathering. Minerals that are soft (hardness lower thaan six) can be easily abraided and blasted. Slope - On steep slopes weathering products may be quickly washed away by rains. On gentle slopes the weathering products accumulate. On gentle slopes water may stay in contact with rock for longer periods of time, and thus result in higher weathering rates.· Porosity and faults and shears in materials Porous sediment equals better circulation and thus faster weathering process. Impermeable rocks will mean that no or little circulation will take place in rocks and weathering will be slower. Enhanced weathering rate occurs if faults and shears are present in rocks. * Exposure- Rock that is exposed to the atmosphere tends to weather much quicker. Bed rock that is covered by soil and vegetation may not weather as quickly. * Particle Size- The particle size of the material can affect the rate of weathering. The smaller the particle size, the faster it will weather. The more surface area that is exposed, the more it will weather.

Are there any splinter faults on the Hayward fault?
Yes, but no significant ones.
What is the name for tree roots forming out of rocks?
Biological weathering; Its a type of weathering which involves the breaking apart and disintegration of rocks throught the process of tree roots out growth or development by opening of cracks, joints and faults in rocks.
Which is a significant thematic question raised by The Pardoner's Tale?
"Is it more moral to admit one's faults or deny them?" is a significant thematic question raised by The Pardoner's Tale.
What is the name of the earthquake fault in ca?
There are many faults in California. The two most significant faults are the San Andreas Fault and the Hayward Fault.
Where are mountains belts form?
Mountains are most often formed on faults. Because these faults occur due to the space between tectonic plates, these faults take the form of lines. Thus, the thin belts are along these long lines.
Which is best at weathering rocks?
Most surface rock is weathered by water. Naturally acidic rain and groundwater can react chemically with rock, causing dissolution and oxidation. Freezing water can also act on the rock mechanically, forcing open gaps and faults for further weathering attack by liquid water.
Are the three types of faults normal faults backward faults and slip faults?
No. Your terminology is close but not quite right. The three main types of faults are normal faults, reverse faults, and strike-slip faults. Strike-slip faults may also be called transform faults.
What are fault lines and what way does tectonic plates move at the faults?
a faultis a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement along the fractures as a result of earth movement.the plates move at the faults becausestress builds up in rocks and when it reaches a level that exceeds the strain threshold it will move along the faults

What kind fault lines are there?
There are 6 types of fault lines. Strike-slip faults, dip-slip faults, oblique- slip faults, listric faults, ring faults, and synthetic and antithetic faults.
Why is the hawthorne effect significant?
The Hawthorne Effect is significant due to the underlining fact that it brings out the faults of an organization during the test and giving the reader the conclusion that human behavior is affected by supervision in all aspects of life especially in the workplace.
