How can physical features influence culture patterns and distribution?
Physical features of a region influence human activities in many ways. If the physical feature won't allow them to build in a spot or creates barriers the people won't want to be put there. For example if someone wants to build somewhere, but they don't have access to water they wont build there because they don't have the right conditions to live there. So basically, it affects where and how people live in the region. Do they have to walk far to get water, or can they get it right in their sinks? can they have cattle, or livestock, large houses, what are their houses made of? ...etc.
What is A spot of fertile land in a desert fed by water from underground springs?
It's an oasis(:
How much does the concentration change each time the pH changes one spot?
The concentration changes by roughly a factor of 10.
How many ounces of crossbow per gallon of water?
1 1/2 to 2 ounces of crossbow per gallon of water when doing spot treatment.
How does Collection occur in the water cycle?
when it rains, the rain moves into a spot where it stays there, that's collection, and that's how it occurs
Is sand flowing through an hour glass an chemical or physical change?
It is not really a change, at all. Sand is moving from one spot to another. If it truly had to be categorized, I would put it under a physical change. A physical change would be a change in an object you can see with your eyes. However, the chemical makeup of that object does not change. In other words, no new chemical is formed. For example, water may freeze or evaporate, but the chemical makeup of water, no matter what state it is in, is H2O. A chemical change would would result in the formation of one or more new chemicals. For example, burning paper is a chemical change. You have paper and fire, and when you burn the paper up, it gives off CO2, and charred paper, which is different from regular paper.
What chemical change is there when a rust spot forms on a bike fender were some paint came off?
Oxidation
Is spilling bleach on jeans a chemical change and why?
It is a chemical change because the change of the color involve a chemical reaction.
How does earth water change?
water can change the earths surface by breaking down rocks into sediment and then the wind blowing them to a different spot to change the earth.(An example is the Grand Canyon.)
What evidence tells you that a chemical reaction has occurred?
new substances are formed with new properties.when a object changes its formA chemical reaction has occurred when the chemical identity of a the reactants is different from that of the products. The evidence for this could be obvious or very subtle. For instance, if a colorless gas reacts to form another colorless gas, there would be no visible sign of the reaction. However, often a chemical reaction will cause a change in color or the formation of a solid. The tools you might use to determine if a reaction has taken place depends a great deal on what the suspected reaction is (or what the products formed would be). The most common method is to use analytical chemical technique to verify the presence of the product molecules, or the disappearance of reactant molecules.Note that there are many physical changes that can be confused with chemical changes. For instance, boiling water or freezing water results in many changes in the properties of water, but those are physical changes, not chemical ones. But whether water is liquid, solid or a gas, it is still water, and that is why it is a physical rather than chemical change.See the Related Questions for more information about the difference between chemical and physical changes.(Emperor-A) Here are some evidence they are-A colour changeA gas given offA temperature changethere are 7 ways to spot if a chemical reactions is occurring:1. A Temperature change2. A color change.3. A precipitate is formed (an insoluble substance)4. A gas is given off.5. Light may be given off6. Odor may be given off7.

These include;- Change in color or luster. The release of gas or vapor. (noticeable odor or formation of bubbles) Change in temperature. (either cooling down or heating up) Formation of a precipitate. The release of heat and/or light & sound. A change in volume. The melting point or boiling point changes. A change in electrical conductivity occurs. A change in any distinctive chemical or physical properties occurs. Not all of these changes are necessarily proof of a chemical change, but they are a good indication and a starting point for further investigation. e.g. ruling out physical changes.
