A mushroom-shaped landform
consisting of a column of less resistant rock supporting a broader extent of
wind-resistant rock is termed a yardang. Yardangs form in environments where

Answer:
Hot, humid temperatures than today.
Explanation:
- The Carboniferous period is was a geologic period that spans about 60 mn years ago and is named for the coal-bearing period. In the beginning, the climate was warm and hot had temperature about 20 degrees, but in the middle cooling occurred and the temperature was about 12 degrees.
- The cooling and drying of the climate lead to the Carboniferous rainforest. The planet was much hotter and more humid than we see it today and had more carbon dioxide and greenhouse gases in the atmosphere than exists today.
Answer:
The sun gets its energy from the process of nuclear fusion. This process occurs in the sun's core or interior, where temperature and pressure are extremely high. During most of the sun's life, energy comes from the fusion of hydrogen nuclei
Explanation:
<span>A sustainable system refers to producing less or probably non-existent debris that are caused by the production of a particular material (i.e. produce, energy). This is a sustainable form of production of coupling algae growth and fish farming because you no longer need the supply of fish feed from other sources that are made artificially but rather, you are using the available algae growth that you are culturing. Farm fishing alone is non-renewable because this produces much waste that can directly harm the environment.<span>
