Why is it difficult to divide precambrian time into smaller time units?
The Precambrian interval of earth history is difficult to study because of its tremendous age. Many of the original rocks have been destroyed by weathering and erosion, or have been greatly altered by heat & pressure during burial, a process known as metamorphism.
How is the weathering of rock helpful to life on earth?
Weathering is the breaking down of rocks into smaller units to form soil.Weathering of rocks is helpful to life on earth because when rocks breaks into smaller units or sizes it forms soil which enable mankind to use in his daily life.Rocky rocky rocky ;3
What is the name of a chemical or mechanical process in which rocks exposed to the weather are worn down by water wind or ice?
Weathering is a chemical or mechanical process that results in the creation of smaller and smaller units of rock.
Are Fahrenheit units the same as Kelvin units?
kelvin unitsl
2 units of mass?
There are several different units of mass used. Grams, kilograms, and milligrams are all different SI units of mass.
Is it possible to have erosion without weathering?
weathering happens before erosion because when a storm comes it washes away the soil and that causes the soil to erode.
Why must weathering happen before erosion?
In 'normal' situations, a body of rock must first be broken down into smaller units before it is able to be transported by wind, water, and ice. The breaking down of rock is called weathering, and the transportation of weathered rock is called erosion.

Where would -20 appear on a number line?
Usually 20 units to the left of the origin (or zero point).
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.
Is there a website that I can compare air conditioning units prices?
One of my favorite sites to use is Bizrate. When you go on their site, search "compare air conditioning." Many different units and their prices with appear.
What is unit square?
Square units measure area.
What are the merits of ceramic valves?
As opposed to a rubber tap washer the benefits are significant, though more costly. The on-off action is limited to say 90 degrees of tap turn, no more and no less. Particular strength is not required and the action is more suited to elderly persons. Units can be easily constructed to be opposite handed making symmetrical pairs for lever tops. The unit does not wear out so readily, and to an extent is self cleaning when chalk deposits are a problem in hard water areas. Ceramic valves have better wear resistant, erosive resistant and heat resistant. Besides, they have the advantages of environmental protection and energy saving. Ceramic valve makes full use of the engineering ceramic material's properties of wear resistance, erosion resistance and high hardness.
What values can not be measured using SI units a. length b. density c. temperature d. all of the above?
The correct answer doesn't appear in the list of choices.Each of those three quantities CAN be describes in SI units.
Where does word by default place the tab stop on the ruler?
They are not placed on the ruler, but on the narrow bar underneath it. On manual tabs appear on the ruler. The default tabs are at every half an inch or 1.27 centimetres, which are equal values. It just depends on what measurement units you are using.They are not placed on the ruler, but on the narrow bar underneath it. On manual tabs appear on the ruler.
