Answer:

A "luminous shell of gas" ejected from an "old low-mass star" is called a 'planetary nebula'.

Explanation:

When the red giants stars are in the last stage of their life, they eject a colored ionized gas which forms a shell-like structure around the star.

This structure appears to have a ring shape. It exhibits colors like red, green and blue.

The term 'planetary' in 'Planetary Nebula' is believed to be debatable by a number of astronomers because the planetary nebulas are related to dying stars, not planets.

How are Norway and Spain similar in climate? How are they different?

loris [4]

Hi Moran

I don't think there is a big different at all but what I know is that Norway is colder and has more rain.

Another different is because Spain is closer to the equator but Norway is closer to the arctic.

I hope that's help ! Have a nice day :)

From the standpoint of water availability, which of the four soils; crushed silt loam, aggregate silt loam, fine sand or coarse

earnstyle [38]

Answer:

fine sand

Explanation:

Permeability id a scientific index of the soil to have air and water pass through the soil pore and spaces. As clay soils have a fine texture, with loamy soils moderately textured and sandy soils coarsely textured thus permeability changes from slow to rapid.

As sandy soil is highly permeable i.e 5.0 cm per hour and clay soils having the least i.e 0.05 permeability. Loamy soil is composed of sand, silt, and a smaller amount of clay.

From an agricultural perspective, the soil permeability depends upon the percentage of the see-page and the chemical makeup of the soil. Thus crops can grow more easily this type of soil as the particle size is minute and fine.
