Answer:

<u>B. Tectonic</u>

Explanation:

Playa is generally dry and flat. This valley is located in New Mexico, Bootheel region. Valley is noteworthy for the lake Playa i.e a dry lake in the north. This region of desert extends to northwards to the foothills of various mountain ranges, canyons and washes. It's a liner north to south trending towards mountain ranges and flat in south. Playas are formed due to evaporation of water that leaves salt behind it may be underlined with stratified sand, silt and clay. The salt flat valley also called salt marshes. A variety of playas bed occurs in restricted basins that are without outlets. The salts that form these are Chlorine, sulfate, and carbonate. Hence this landform is a product of tectonic forces and factors that influence the growth and development of this valley.

3. The greenhouse effect is driven by the fact that greenhouse gases are:

Answer:

Good absorbers of longwave radiation and poor absorbers of shortwave radiation

Explanation:

Gases in the atmosphere such as carbon dioxide, water vapor, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons absorb and re-radiate the sun's energy maintaining the Earth's temperature at around 33 degrees Celcius, this happens especially with infrared light that wants to go back to space, greenhouse gases are good at absorbing and emitting radiant energy within the thermal infrared range (range from about 700nm to 1mm), IR is considered long-wavelength radiation.

Considering this information we can assume greenhouse gases are good absorbers of longwave radiation and poor absorbers of shortwave radiation (such as UV or gamma rays)

I hope you find this information useful and interesting! Good luck!

How are the factors that make earth habitable?

iogann1982 [59]

Answer: D. both A and B

Explanation:

Earth is the only planet that is capable of supporting life as we know it due to the presence of temperature, oxygen, an atmosphere and energy.

All the above contribute in the following ways;

Atmosphere - The atmosphere is sort of like a protective barrier around earth. It destroys a lot of foreign objects that fall on earth and traps the sun's rays such that we keep us adequately warm. It also contains both oxygen and carbon dioxide which living things rely on.
Energy - The presence of energy sources on Earth enables us to be able to survive. Energy sources like fire, water, and solar enable us to do things such as cooking and electricity generation, that ensure our survival.
Nutrients - The nutrients available on Earth ensure that living things can grow and survive.
Temperature - A very important factor, Earth has the right amount of temperature necessary for the proliferation of life. It is not too cold that living things are unable to metabolize food and freeze and is not too hot that life cannot survive.
