The thermosphere protects the earth from uv radiation coming from the sun. select the best answer from the choices provided t f

False

Explanation:

It is the stratosphere layer of earth that protect us from harmful UV radiation. Basically ozone gas protects earth from UV radiation and nearly 90% of the ozone in atmosphere is found in the stratosphere at an altitude of 16 and 48 kilometers above the Earth's surface.

Ozone is found in a concentrated form in stratosphere only. This ozone has a tendency to absorb ultraviolet light from the Sun and protect the earth from the harmful effects of UV radiation.

Thus, it can be said that it is the stratosphere and not the troposphere that protects the Earth from UV radiation coming from the Sun

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.
