How long does the temp have to be below freezing to freeze the roots of large plants?

Freezing temperature is usually referencing the point at which water freezes. For most purposes this is 32° F or 0° C. While some hardy plants may survive these temperatures, herbacous garden plants may be killed by temperatures even above of this. Unfortunately, the lowest temperatures plants can tolerate and still live will vary from plant to plant, so you may need to find the specific temperatures that the plants growing in your garden can tolerate.

What freezing point of ultra low sulfur diesel?
Diesel is a mix of hydrocarbons, and the components have different freezing points. For Number 2 diesel, as the ambient temperatures drop toward 32 degrees F (0 degrees C), it begins to cloud, due to the paraffin in the fuel solidifying. As the temperatures drop below 32 F, the molecules combine into solids, large enough to be stopped by the filter. This is known as the gel point, and generally occurs about 15 degrees F (-9.5 degrees C) below the cloud point. This wax then forms a coating on the filter which results in a loss of engine power. The same thing happens on starting an engine when the temperature is below freezing. The filter becomes almost instantly coated with wax - usually, enough fuel gets through to allow the engine to idle, but not attain operating RPM. There are two common ways to overcome this: one is a diesel additive, the other is a fuel heater. In Alaska and other colder climates, trucks are running regularly at minus 51 degrees or lower so as you see it depends on additives and heating but to freeze as in turning solid you would need laboratory conditions as nature cannot go cold enough to freeze to a low enough temperature.
When large areas of continents are covered by ice what happens to the rate of chemical weathering?
they freeze to death
How did changes in the environment affect large animals?
the plants were dead
What is a Large area with characteristics climate soil plants and animals?
Its a biome.
Explain how a global temperature increase could affect plants?
A small increase in temperature may help some plants, but will be damaging to others. A large increase in temperature will kill most plants.
Rain falls through a layer of freezing air that is large enough to freeze the rain What type of precipitation forms?
Sleet
How does hale form?
Hail is formed when a thundercloud has a strong updraft, a lot of water, and a large cloud layer with below freezing temperatures. The updraft takes the water up through the cold cloud layer causing it to freeze into hailstones.
When do snowstorms take place?
When there is a large concentration of water in cloud formation, when the air temperature is below freezing.
What effect would freezing and thawing most likely have on a large rock?
Freeze thaw weathering would take place in the cracks on the rocks surface. Depending how long the rock is left, and what type of rock it is, the freeze-thaw would widen the cracks and eventually split the rock.

Can you freeze fresh pasta?
There is no reason why you cant freeze home made pasta , but traditionally pasta is stored by drying it out then storing in air tight containers. If you are freezing it fast freeze it flat then stack when frozen !!! GOOD LUCK !!!
Dust storms and ice storms differences?
A dust storm and and ice storm are two completely different things. A dust storm occurs when a strong wind occurs over an area with loose soil, usually a desert, creating a massive, fast-moving cloud of dust. An ice storm involves freezing rain which occurs when supercooled rain (rain that remains liquid below the freezing point) strikes the ground and other objects that are below freezing. These raindrops freeze on impact, coating everything they land on with a layer of ice. When a large amount of freezing rain falls it is called an ice storm. In these cases the weight of the ice can bring down tree limbs and power lines.
Why did many plants die at the end of the Mesozoic?
Based on the popular theory that the dinosaurs went extinct due to the impact of a large asteroid, scientists think that the asteroid caused large amounts of debris to fly into the atmosphere, blocking out the sun. This caused global temperatures to drop, thus freezing the plants. In addition, without the sun the plants could not carry on photosynthesis, which caused them to die.

Does water in a water tower freeze when it is cold?
It would have to be awful cold for an awful long time for a water tower to freeze solid. The water is typically moving most of the time as it flows in and out. Water being pumped into the tower is going to be above freezing. And the large mass of water makes it pretty hard to get that cold. In colder climates, they may even have some sort of heating device, it only has to keep the water above freezing. And I'm sure the top edges get some freezing around them. ASS yes it could, anything could happen!!!
Why do not burn hydrogen instead of gasoline in car engine?
Hydrogen fuel cells are very expensive to build. They cannot operate below freezing. They require a large storage container. There is no infrastructure for refueling.
Can anyone describe how plants and animals are classified?
Yes, but it is too large a subject to cover here. Look in the related links I will make below for this information.
