Answers

Answer:

A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world.

Explanation:

Evolutionary theory, atomic theory, gravity, quantum theory, and plate tectonics are examples of this sort of over-arching theory. These theories have been broadly supported by multiple lines of evidence and help frame our understanding of the world around us.

The fossils found in the different layers of Earth are listed below. Layer 1: Fossil A (oldest fossil)
Layer 2: Fossil B
Layer 3: Fossil C
Layer 4: Fossil D (youngest fossil)

Which is the topmost layer?
Layer 1
Layer 2
Layer 3
Layer 4

Answers

Answer:

Option (4)

Explanation:

According to the law of Superposition, the rocks that are present at the base are the older rocks and the rocks that are deposited on the uppermost layer are the younger rocks. The younging direction of the rock is towards upward.

From the given condition, four fossils are found from four layers, of which the bottom layer contains the oldest fossils and the top layer contains the youngest fossils. The fossil A is in the layer 1 (oldest), fossil B is in the layer 2, fossil C is in the layer 3 and fossil D is in the layer 4 (youngest).

So, from the Superposition law, the rock layer that is the topmost layer is the layer 4 which contains the youngest fossil (fossil D).

Thus, the correct answer is option (4).

The answer is layer 4

Describe a human activity that disrupts the carbon cycle and the consequences of that disruption

Answers

Hey there!

The Carbon Cycle refers to photosynthesis, during which plants take the CO2 we make and release it back into the atmosphere. One way this process could be interrupted is if a company cuts down a lot of trees for land, destroying many of the plants that keep the Carbon Cycle moving.
