Answer: Option D.
Crystalline and rigid.
Explanation:
When liquid freezes to ice, it becomes solid and this is crystalline and rigid because a solids for crystals which means solid atoms, molecules or ions are orderly arranged in structures which form of crystal lattice in all sides. The structure of solid becomes rigid , it does not take the container shape like liquid and it does not expand also like liquid. it volumes reduces.
<span>The statement is a hypothesis rather than a theory because it depends on the volume of the rainfall on sand dunes increases, therefore, there will be a result or conclusion that the erosion of the sand dunes will also increase.</span>
The two factors about the ecology of the great plains did farmers fail to understand
The role the native grasses played in the environment
That local weather patterns were subject to periodic drought
<h3>What factors about the ecology of the great plains did farmers fail to understand?</h3>
- Environmental change has been significantly less drastic than the two-thirds of the grassland that farmers were unable to successfully plow for crops.
- The majority of such area still has native vegetative cover, despite the fact that virtually all of it has been extensively grazed by cattle and in much smaller amounts by sheep and horses.
- Two key climatic gradients—an east-west gradient of increasing precipitation and a north-south gradient of increasing temperature—which both produce drought—control the spread of both natural ecosystems and land use management.
