Answer:
Their depth, their height, the soil, and the proximity to the fault
Explanation:
Coarse sand grains deposited across the landscape in an amorphous sheet is known as a sandplain. Wind plays a fundamental role in the formation of these sandplains by redistributing sedimentary material. The situation is analogous to the creation of dust devil tracks on Mars.
Coarse sand grains deposited across the landscape in an amorphous sheet is known as a sandplain. A sandplain emerges due to the action of wind which plays a crucial role in redistributing surface material such as sedimentary rock or shells of living things. The process involved includes the stripping of material from specific areas, like canyons on Mars, and depositing them elsewhere to form expansive dune fields or sandplains.
This concept strongly mirrors the way dust devils on Mars strip away a thin coating of dust, leaving behind dark tracks as seen in high-resolution photos from Mars Global Surveyor. Likewise, the same gravitational forces work on Earth to create similar grains based landforms on the landscape.

Explanation:
Back in the Cretaceous era, the East Coast was covered with massive ferns, flowers, and unusual fruit trees. Many have long since become extinct or evolved into modern species. But with the help of scientists, such as Dr. James Mickle, knowledge of those plants is starting to be unearthed, providing a window into that primordial era.
In 1971, one of Mickle's colleagues from Texas was digging in the quarry when he found a well-preserved fossil of Leptocycas gracilis, a variety of sago palm that is now extinct. This specimen is the only one found intact, making it an important find in paleobotany.
This plant was similar to sago palms found today, but it was much taller and thinner, a fact that puzzles Mickle and other scientists. It's like finding a fossil of a human ancestor who was 12 feet tall. It's not clear why the palms shrank so much as they evolved.
Mickle's studies show that many of the plants that grew (in North Carolina) in the Cretaceous period are similar to species now found in the tropical climate of the southern hemisphere. This indicates that North Carolina's climate was much hotter in the past, but it is not clear why and how the cooling occurred. "Right now, we're in one of the coldest periods in Earth's history," Mickle said.
By examining the fossil record, Mickle and other paleobotanists have learned that the Earth's climate has changed drastically, with the Triassic period being hot and dry, and the Cretaceous period being cooler and wetter.
Polynesian is the answer. hope this helps.
