Which rock layers are most likely the same age according to the ideas of William Smith?

A. layers made of the same chemicals

B. layers of equal density

C. layers with different fossils

D. layers with similar fossils

11 answers

According to the ideas of William Smith, the correct answer is:

D. layers with similar fossils

William Smith, known as the "Father of Stratigraphy," emphasized the importance of fossils in dating and correlating rock layers. He proposed that rock layers with similar fossil assemblages would likely be of the same age. This principle is known as the law of faunal succession.

What is in the hydrosphere?

A. soil

B. dolphins

C. rivers

D. Mars

The correct answer is:

C. rivers

The hydrosphere refers to all the water on Earth, including oceans, rivers, lakes, glaciers, groundwater, and water vapor in the atmosphere. Dolphins are part of the biosphere, while soil is part of the geosphere, and Mars is a planet, not part of Earth's hydrosphere.

What is the cryosphere?

A. mountains

B. molten rock

C. earth’s crust

D. earth’s ice

The correct answer is:

D. earth’s ice

The cryosphere encompasses all regions of Earth where water is in solid form, including ice caps, glaciers, ice sheets, and permafrost. It specifically refers to the Earth's ice.

Which event is an example of how the geosphere can affect the atmosphere?

A. earthquake

B. rainstorm

C. tidal wave

D. volcanic eruption

The correct answer is:

D. volcanic eruption

A volcanic eruption can release ash, gases, and other particles into the atmosphere, which can have significant effects on air quality, climate, and weather patterns. This illustrates how activity in the geosphere (the Earth's solid part) can influence the atmosphere.

A major concern about increasing global temperatures is that a large portion of polar ice could detach and melt into the ocean.
If this happened, which two spheres would interact?

A. cryosphere and biosphere

B. cryosphere and hydrosphere

C. hydrosphere and atmosphere

D. geosphere and atmosphere

The correct answer is:

B. cryosphere and hydrosphere

If polar ice melts and enters the ocean, it represents an interaction between the cryosphere (frozen water, including ice) and the hydrosphere (liquid water, including oceans).

Which scientist developed a new model of planetary motion?

A. Kelvin

B. Linnaeus

C. Kepler

D. Hutton

The correct answer is:

C. Kepler

Johannes Kepler developed a new model of planetary motion, formulating his laws of planetary motion in the early 17th century. These laws describe how planets orbit the Sun in elliptical paths, which was a significant advancement in the understanding of celestial mechanics.
