Answers

Answer:

the stage of development of the cultural landscape in the boundary area at the time the boundary was laid down.

Explanation:

Culture can be defined as the general way of life of a group of people living together in a particular location or society.

Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.

A boundary can be defined as an imaginary or real line that seperates two geographical areas from one another. Thus, it is used to separate particular region on the earth from another region based on certain political or cultural factors.

The genetic classification of boundaries relates the political boundary's creation to the stage of development of the cultural landscape in the boundary area at the time the boundary was laid down.

The four (4) main types of genetic classification of boundaries includes the following;

I. Subsequent boundary.

II. Antecedent boundary.

III. Relict boundary.

IV. Superimposed boundary.

A superimposed boundary can be defined as the boundary imposed on a geographical region or area by a colonizing, conquering or an external power and as a result of this, the preexisting cultural organizations and patterns are completely ignored.

Some examples of a superimposed boundary is the geometric boundary between Uganda and Kenya, Iraq and Saudi Arabia, as well as other boundaries imposed on Africa by the Europeans during the era of colonialism.

A change to any gas in the

Answers

Answer:

With the below information, that is for you to decide.

Explanation:

Any changes to the Earth's climate system that affect how much energy enters or leaves the system alters Earth's radiative equilibrium and can force temperatures to rise or fall. ... It absorbs thermal infrared energy with wavelengths in a part of the energy spectrum that other gases, such as water vapor, do not.

This is just what I found on the web. This will help you decide for yourself, or if this is sufficient evidence for you to agree, or disagree. Do not copy and paste the above paragraph, because I just copy-pasted from the web. Thanks, and I hope this helps!

A greenhouse gas is a gas that absorbs and emits radiant energy in the thermal infrared spectrum, causing the greenhouse effect.

What is the Importance of Greenhouse Gases?

Greenhouse gases such as co2, methanol, n2o, and certain synthetic mixtures absorb some of the Earth's emitted energy, causing heat to be trapped in the environment. This heat-trapping modifies the Earth's radiative balance—the balance of energy taken from the sun and reflected by the Earth—altering the global and regional climate and weather patterns.

Thus the statement is True.

How do yaks and horses eat differently?

Answers

Answer:

Horses eat the tips of the grass. Yaks yank the grass out by the roots.

Explanation:

Parasite control for livestock can take several forms: chemicals sprayed or wiped topically, ear tags, and even pressed blocks that deliver insect growth regulator along with vitamins and minerals. We have had quite good success for the past 14 years spraying our yaks a couple of time per week with Permethrin 10% insecticide spray. We buy it in concentrate form and mix it up in 1⁄2 gallon pump sprayers. When the yaks come up for breakfast, we lock our ten animals in the corral and spray both sides as they move around. Yes, they get in- stant relief from the biting insects, but this is not a fun job--and heavy rain will wash it all off.
