Explain, in terms of pressure, why a camel is better at crossing a desert than a horse. Camels and horses have a similar mass and the weight
bearing part of a horse's hoof can be assumed to be approximately
180 cm2.

camels are better than horses in desert as camels are adapted to the hot and humid climate and camels can store fats in his humps

Camels do better.

Explanation:

Well, if you have a horse in the desert, the chances of living are slim. There is almost no water in the desert, but for camels, their humps are stored with many gallons of water, so they could survive months in the desert without having to stop for water every second.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

it would lead to upper respiratory infections and pneumonia.
