Geography

There are many ways to identify when a physical change has occurred. This can be done by recognizing reversible changes or eliminating chemical changes.

Physical changes involve state changes in matter and energy. These changes cause the matter to change form, but no new material is generated. Matter may alter in size, shape and color. When substances are combined but do not chemically react, physical changes take place.

A physical change can be recognized if it is reversible, especially if it involves a phase transition. For instance, if water is frozen into an ice cube, it can be melted back into water.

Sometimes eliminating the potential of a chemical transformation makes it easier to spot a physical change. There may be a number of signs that a chemical reaction has taken place.

faust18 [17]

gregori [183]

Answer: The elements of a folktale in the excerpt include:

The story is being narrated in third person.

The story is set in the past (at a time when people kept slaves).

The scene is simply described. That is scenes are not described in explicit detail.

If John is the hero of this story, then another element of folklore involved would be - The hero is usually courageous. We can assume this because there were dire consequences for slaves eavesdropping or generally annoying their masters such as beatings, starvation, even torture. For John to take the risk shows bravery.

Explanation:

"Folk" is an old english word for "people". And tale means a fictitious story or true story narrated with lots of imaginative descriptions. Folktale are basically imaginative stories told by people to entertain, convey a moral lesson, pass down traditions etcetera. Most children's stories are folktales.

Folktale elements are the characteristics that make up a typical folktale.

Some of these elements include;

• The hero/heroine is usually good and the antagonist is usually evil.

• The hero and heroine are usually young.

• The heroine is usually fair, kind, charitable, and caring.

• The hero is usually honorable, courageous, unselfish, and caring.

• Place is described easily and briefly that fits the typical geography of the culture.

• Time is usually in the past (usually long-ago) imbedded within history.

Time is fantasy time (Once upon a time sets the stage and They lived happily ever after closes the tale.) any time or any place, timeless or placeless, or long long ago.

The story is usually verry simple to follow or read.

Conflicts are usually resolved with great deeds or acts of human kindness related to good and bad/evil.

The story is usually narrated in third person.

Examples of human-environment interactions
vichka [17]
Human-environment interactions is the intercations between the human social system and the ecosystem.

One example could be that the people in rural depends on the natural resources,such as the soil,land,and animals to farm,build facilities and hunt to sustain livelihood. Resources taken from the ecosystem are used, however one does not simply carry on like that. For instant when there is excessive cultivation, the soil nutrient would be used up causing soil erosion,leading to the soil no longer fertile enough to farm. Therefore,measures are carry out to preserve the land like growing different crops and using fertilizer.

Hope it helps!
