Radio waves are electromagnetic waves and as such travel at the speed of light. Waves emitted a century ago would be 100 hundred light years away. A light year is the distance light travels in one year. In one year light travels about 5.9 trillion miles. therefore the waves traveled about 590 trillion miles in a century.

Which of the following statements is correct?
patriot [66]

Answer:

B) Distinctly alkaline diagnostic horizons, thin profiles, lack of organic material, and dominance of sandy materials are features most closely associated with aridisols.

Explanation:

The aridisols are types of soils that are found predominantly in arid areas. They are soils that are not considered as fertile, and are near the bottom by quality of soils. These soils are lacking organic material, and also are very exposed to erosion, with the primary reason being the climate, as it doesn't allow for lot of vegetation to grow. The horizons of the aridisols are distinctly alkaline diagnostic ones, with the profiles being very thin and labile. The top layer of the soil is dominated by sandy material, which is a result of the extensive weathering and erosion in their surroundings, so the wind is mostly transporting small sandy grains and covers most of the area with them.

For the same insolation, order these regions from highest absorption to lowest
abruzzese [7]

1. The Sahara Desert

2. Grassy plains of Kansas

3. Lake Michigan

4. An Arctic glacier

Explanation:

The insolation is not the same across the planet, and it varies from one place to another. The variations occur mainly because of two things, one being the latitude and the other being the the type of surface.

The places that are on lower latitudes get more direct sunlight, thus more concentrated, and they manage to absorb more heat. The places on higher latitudes get sunlight at very low angle, thus very dispersed, and they absorb much less heat.

The surfaces that are without cover, on land, tend to have higher insolation. The surfaces that are with cover, or are water bodies, ice bodies, have lower insolation.
