Earth and Environmental Science Final Exam

Front

What is the impact of urban development on natural habitats?

Back

Urban development removes plants that absorb water and creates hard surfaces, decreasing infiltration and increasing surface water runoff, which can lead to flooding.

Front

What process primarily produces energy in the Sun's core?

Back

The fusion of hydrogen nuclei (protons) into helium nuclei is the primary process that produces energy in the Sun's core.

Front

What typically forms at a divergent plate boundary?

Back

Mid-ocean ridges typically form at divergent plate boundaries.

Front

How does volcanic ash affect global temperatures after an eruption?

Back

Volcanic ash decreases global temperatures by reflecting sunlight back into space.

Front

Which renewable energy source has the least environmental impact?

Back

Wind power has the least environmental impact among renewable energy sources.

Front

Define infiltration in the context of hydrology.

Back

Infiltration is the process by which water on the ground surface enters the soil.

Front

What is eutrophication and how is it caused?

Back

Eutrophication is the enrichment of water bodies with nutrients, often caused by runoff from agricultural fields, leading to excessive growth of algae.

Front

Explain the concept of a mid-ocean ridge.

Back

A mid-ocean ridge is an underwater mountain range formed by plate tectonics at divergent boundaries where tectonic plates are moving apart.

Front

What is the role of plants in preventing flooding?

Back

Plants absorb water and help maintain soil structure, which increases infiltration and reduces surface runoff.

Front

Describe the process of nuclear fusion.

Back

Nuclear fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing energy, as seen in the Sun.
