The answer is - Sponge.
Sponges are very lightweight, they have large percentage of voids as well, this practically means that they have low density structure. Their density is smaller than the density of the water, so this means that it will float on the water instead of sinking.
Answer:
Explanation:
Inner planets orbit the Sun at higher speed than outer planets.
Earth is slightly closer to the Sun on one side of its orbit than on the other side.
Potassium-argon dating
One of the most widely used is potassium–argon dating (K–Ar dating). Potassium-40 is a radioactive isotope of potassium that decays into argon-40. The half-life of potassium-40 is 1.3 billion years, far longer than that of carbon-14, allowing much older samples to be dated.
absolute dating is based on calculations of the age of rock strata based on half lives of minerals, relative dating is based on the assumed age of fossils found in the strata and the laws of super imposition.
