EAS SEM A 2023 Final Exam/Semester Test Review

Front

What are convection currents?

Back

Convection currents are the movement of fluid (liquid or gas) caused by differences in temperature and density, which results in the transfer of heat.

Front

What is the order of energy flow from the sun to Earth?

Back

The order is: nuclear fusion; radiation; convection currents; radiation.

Front

What happens at the Mid-Atlantic Ridge?

Back

Magma rises from the Earth's crust, pushing the North American plate and the Eurasian plate away from each other, causing the Atlantic Ocean to become wider.

Front

What principle allows geologists to determine the age of rock layers?

Back

The principle of cross-cutting relationships states that a geologic feature (like a fault) that cuts through another is younger than the feature it cuts.

Front

What type of rock commonly contains fossils?

Back

Sedimentary rock is the type of rock where fossils of similar species can be found, providing evidence for the Theory of Continental Drift.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process by which two light atomic nuclei combine to form a heavier nucleus, releasing energy, and is the source of energy for the sun.

Front

What is the significance of the Theory of Continental Drift?

Back

The Theory of Continental Drift explains how continents have moved over geological time and provides evidence for the movement of tectonic plates.

Front

What is the role of radiation in energy transfer from the sun?

Back

Radiation is the transfer of energy through electromagnetic waves, allowing energy from the sun to travel through space to reach Earth.

Front

What is the difference between igneous, sedimentary, and metamorphic rocks?

Back

Igneous rocks form from cooled magma or lava, sedimentary rocks form from the accumulation of sediment, and metamorphic rocks form from the alteration of existing rocks due to heat and pressure.

Front

What evidence supports the Theory of Plate Tectonics?

Back

Evidence includes the fit of continental coastlines, fossil distribution across continents, and the presence of similar rock formations on different continents.
