How do you identify rainy clouds?

Nimbostratus clouds are low, thick and dense clouds that produce steady precipitation. These clouds spread out from one end of the horizon to another as weather moves through an area.\nCumulonimbus clouds reach high into the atmosphere and feature heavy precipitation and strong gusts of wind. These clouds, when seen from a distance, have white tops and may contain an "anvil" shape at the pinnacle as warm air quickly rises within the cloud. Cumulonimbus clouds produce thunderstorms under the right conditions.

Do fish reproduce sexually or asexually?

Though the entire reproductive process is sexual, many times the fertilization of the eggs of the female take place outside of the body rather than internally as happens with humans and other mammals.\n\nFemale fish of most species lay a large number of eggs in an area. The male of the species then produces sperm in a substance known as milt. The milt is then released from its body as it passes a patch of eggs.

What is mature soil?

Soil is formed when rocks and parent materials are acted upon by weathering forces under the influence of soil-forming factors. However, the formed soil is a loose, disorganized and unconsolidated mass of particles of various sizes. The age of soil is determined by the level of weathering and the extent to which parent material is stratified into horizons or soil layers. Mature soils tend to have more and thicker horizons and are classified as older as there are more differences in the properties of soil between two adjacent horizons.

What is the function of the common bile duct?

Bile is produced in the liver, with bile salts as its major component. Bile has a yellow-green color that comes from a different substance, bilirubin, that comes from broken down red blood cells. During fasting, about 75 percent of the bile produced in the liver is released into the gallbladder, while the rest travels on through the common bile duct into the intestines. The gallbladder absorbs water from the bile stored in it, and concentrates it to a large degree.\nOnce food is ingested, hormonal signals cause the gallbladder to release bile. The gallbladder releases between 50 and 75 percent..

How do I describe the motion of particles in a solid?

The solid state is one of the three normal states of matter. In solids, intermolecular forces hold the particles together tightly. Heating the solid increases the vibration of the particles. Once the material reaches the melting point, the solid begins transforming into a liquid. The particles, while still tightly packed, have room for fluid or sliding motion, allowing the material to begin to flow and take the shape of its container. Once it reaches the melting point, the addition of heat energy does not increase the temperature as the energy is breaking the intermolecular forces. Once the ma..

How do you figure board feet?

Measure the thickness of the boardMeasure the thickness of the board using quarters of an inch. The thickness of boards over 1 inch is expressed as an improper fraction, so a 1 1/2-inch stock is 6/4 lumber. Measure the length and width of each boardUse the tape measure to determine the width of the board in inches. Measure the length using either feet or inches.Calculate the volume in board feetUse the formula to find volume of board feet: (length x width x thickness)/144. If you measured the length in feet, divide the product by 12.Calculate the cost of the lumberMultiply board feet by the st..

What is the electron configuration for tin?

Although tin has a completely full 4d orbital, most sources classify it as a transition metal. In nature, relatively little tin can be found as a free element. Instead, most occurs as tin dioxide, or SnO2, in the ore cassiterite. Some tin is found in an alloy called stannine, with the chemical formula Cu2FeSnS4. Important tin alloys include bronze, which is 80 percent copper and 20 percent tin, and solder, which is 67 percent lead and 33 percent tin.

How do volcanoes help the environment?

According to Oregon State University, volcanoes provide incredibly nutrient-rich soil that allows surrounding crops to grow. Volcanic ash itself contains numerous minerals that are beneficial to plants in the surrounding environment. The finer the ash, the easier it breaks down and combines with the soil, improving the plant life in the area. The rich soils created by volcanic flanks provide an excellent habitat to numerous species, making volcanoes almost as beneficial to life as they are destructive. Because volcanoes are so steep, people tend to avoid climbing them, which makes them a haven..

What are some examples of produers in the tundra?

Scientists recognize two different types of tundra: alpine and arctic. Alpine tundras are located at high elevations in mountains around the world, while arctic tundras blanket the northern tip of North America and Asia, as well as some parts of Europe. Characterized by low year-round temperatures and relatively little precipitation, tundras are bleak habitats for much of the year. However, in the brief spring and summer, meadows and fields harbor a carpet of lush vegetation and small flowers. Because tundras are cold for most of the year, the ground is frozen all year long – only the upper ..

How do snowstorms form?

A snowstorm, also referred to as a blizzard, is a combination of strong winds, below freezing temperatures and intense snowfall. The severity of a snowstorm depends on how fast the warm air moves over the cold air and the amount of moisture available. Some of the most destructive snowstorms, such as the Blizzard of 1888 and the Buffalo Blizzard of 1977, posted snowfall totals in excess of 60 inches and winds up to 69 mph. Snowstorms are often further broken down and classified as snow flurries (short, low-intensity snowfall), snow showers (longer periods of snow with varying levels of intensit..
