Answer:
Option (1)
Explanation:
According to the law of superposition, the rocks that are found at the bottom of an undisturbed sedimentary sequence are the oldest rocks as these layers are initially formed due to the process of deposition, sedimentation and lithification, and with progressive sedimentation, the rock layers that are formed at the the apex portion are the youngest rocks.
So, the fossils found in bottom rocks are the oldest fossils, and those fossils that are found in the top layer are considered to be the youngest fossils.
Thus, the oldest fossils are the ones that are found in the deepest strata.
Therefore, the correct answer is option (1).
Answer:
1. Answer: Light can travel in a vacuum, and its speed is constant if the source is moving or stationary.
Light travels at constant speed in vacuum even if the source is moving or stationary. If the source is moving, the apparent frequency/ wavelength changes.
The theory of evolution will be best supported by the evidence showing a species changes over time. Thus, option A.
Basic evidences for proving the theory of evolution are anatomy, Biological morphology, Fossils and direct observations. There have been various theories for the proof of evolution like structural similarities in an embryo formation pointed towards common ancestors. Theory of Natural selection embarked by Charles Darwin to show genetic variations picked by organisms in whole population.
The most authentic theory over evidence for evolution is Paleontological theory which includes study, observation and acquired prove of fossils of various organisms in the forms of Petrified, mold and cast, trace fossils, compression fossils, impression fossils, etc.

Answer: Primary succession occurs after a volcanic eruption or earthquake; it involves the breakdown of rocks by lichens to create new, nutrient -rich soils. The first species to colonize an area after a major disturbance are called pioneer species; they help to form the new environment.
