Answer:
The presence of pillow lavas in the oldest preserved volcanic sequences on the planet, the Isua and Barberton greenstone belts, confirms the presence of large bodies of water on the Earth's surface early in the Archean Eon. Pillow lavas are used generally to confirm subaqueous volcanism in metamorphic belts.

<u>Answer</u>:
Concave shape of the wave rock is a physical evidence that supports the evolution of earth due chemical weathering
<u>Explanation</u>:
It is the best physical evidence of collection in the earth’s evolution. The earth surface is 2.7 billion years old, also the basis for formation of Australian continent formation. The wave rock is formed by weathering of the surrounding area, which helps in proving the deposition part, as the wave rock was below the ground, occurred due to deposition of rock years over years. It is made from very tough material from its surrounding. The weathering reduced the surrounding terrain, while the bedrock remained to witness for the history.

Answer:
Severe allergic response causes fluid loss from the blood, breathing difficulty and therefore, is life threatening.
Explanation:
The anaphylactic shock results from the type I allergic reactions during which the presence of an allergen triggers a severe response. It occurs since IgE antibodies are already present in the body. There is a release of histamine and other vasodilators. Vasodilation and increased permeability of the blood capillaries result in the loss of fluid from the blood. Constriction of airways of the lungs causes difficulty in breathing and weakens the heartbeat. Therefore, severe fluid loss from blood and constricted airways make it life-threatening.
