How is radioactive dating used to measure Earth’s age?

Answers

Answer 1

Answer:

The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample. Radioactive isotopes break down in a predictable amount of time, enabling geologists to determine the age of a sample using equipment like this thermal ionization mass spectrometer

Explanation:

Is matter created or destroyed during the photosynthesis process? Explain your answer.

Answers

Matter is neither created or destroyed during photosynthesis. With regards to the law of conservation of matter, the mass of the items framed is equivalent to the mass of the reactant.
neither. photosynthesis demonstrates the law of conservation of matter which states that atoms cannot be created not destroyed; the matter atoms can only be rearranged into new molecules and ions. photosynthesis is aided by enzymes, special proteins, which can either break chemical bonds, or form bonds in molecules.

In addition to your summary, define 3 unfamiliar terms from the article and answer the following question: "How would paving roads with recycled plastic affect the environment? Consider both positive and negative factors."

Answers

Positive: less waste in landfills, less pollution in oceans therefore more wildlife could exist peacefully, and very beneficial to global warming.
Negatives: if the roads were to get to hot from a sunny day the plastic would pollute the air which could cause cancer in humans, and if a car exploded the road has a possibility of catching on fire and spreading.

Which statement describes one of Wegener’s ideas that contributed to the theory of continental drift?

A. The continents drifted apart due to repeated meteor impacts.
B. The continents were once connected as one landmass.
C. The continents have moved apart very quickly due to earthquakes.
D. The continents are magnetically pulled toward or pushed away from one another.

Answers

Answer:

Option B

The continents were once connected as one landmass.

Explanation:

The theory of continental drift suggests that all the continents on the planet were once connected, forming a supercontinent. However, over time they drifted apart as a result of some internal forces of the earth.

The most appropriate option that shows this is option B: The continents were once connected as one landmass.

This statement describes one of Alfred Wegener's ideas that suggests that a very long time ago, the continents were once connected in a landlocked mass. The fact that the continents are separated now shows that the continents are continuously shifting position on the earth's surface

The statement that describes one of Wegener’s ideas that contributed to the theory of continental drift is the continents were once connected as one landmass. The correct option is B.

What is continental drift?

Continental drift theory states that the motion of the earth results from the movement of tectonic plates. The theory tells that the different continents were fitting together.

According to the theory of continental drift, the world's continents were once joined together to form a supercontinent. However, because to some underlying earth factors, they gradually drifted apart over time.

According to one of Alfred Wegener's theories, the continents were previously linked together as a landlocked mass a very long time ago. The separation of the continents indicates that their positions on the surface of the globe are constantly altering.

Thus, the correct option is B. The continents were once connected as one landmass.
