Unit 3 Earth's Formation and Processes- Stemscopes

Why is not more information not available through studying rocks that formed at the formation of our planet?

• Radiometric dating is unreliable

• Rocks formed at the earliest are found in the deepest locations and are unreachable

• Dynamic processes like weathering, erosion and volcanism constantly renew the surface.

• The surface is the product of meteor impacts and does not represent the past.

Which of the following best describes the formation of the solar system?

• The sun ejected rocky material which became the planets.

• A rotating disk of dust and gas was drawn together by gravity.

• On planet broke apart into several planets.

• Several stars cooled and formed the planets.

Why are lunar rocks a better source of data on the early formation of Earth rather than rocks here on Earth?

• The age of the moon is the same as Earth.

• The lack of erosion, volcanoes and tectonic agents.

• The gravitational attraction of the Earth and Moon holds them together.

• The absence of a moon atmosphere to shield it from impacts.

the two sides of the mid atlantic ridge are moving away from each other. This means that the rocks FARTHER away from the center

• have fewer minerals

• are denser

• are consistently older

• are larger

Which of the following observations can be explained by plate tectonics?

• The differences in ages of crustal rock in different locations on Earth

• The sorting of sediments from smaller to larger particles on coastlines.

• The shapes and sizes of rocks in caves.

• The layering of sedimentary rock with youngest on top and oldest on the bottom.

The movement of tectonic plates and the cycling of Earth materials are the direct result

• Nuclear Fission

• Solar Radiation

• Thermal Convection

• Magnetic Attraction

Convergent boundaries usually cause

• Warm, moist climates

• The shapes of continents

• Diversity of plant and animal life

• Mountain building and volcanic activity

The best evidence for early earth is found in

• Asteroids, lunar rocks and other objects in our solar system

• Weathering and erosion patterns

• Fusion in the sun

• Fluctuations in lava flows

Why does the Earth show little to no cratering?

• The Earth has been resurfaced by processes

• The rocky material is less likely to reach Earth

• The Earth formed much later, when there were less meteors

• The atmosphere protected the Earth from all cratering

What evidence would not fit the conclusion that the Earth is 4.5 billion years old?

• Finding rocks that are younger than 4.5 billion.

• Finding rocks that are significantly older than 4.5 billion.

• Rocks found other places in the solar system that are younger than 4.5 billion.

• Rocks found that are different compositions different from rocks from other sources.
