Which layer of the atmosphere contains the ozone layer?

Back

Stratosphere: The stratosphere is the second layer of Earth's atmosphere, located above the troposphere and below the mesosphere. It contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.

Front

What type of plate boundary is most likely to cause the formation of a new landform?

Back

Divergent Boundary: A divergent boundary occurs when two tectonic plates move away from each other, leading to the formation of new landforms such as mid-ocean ridges and rift valleys.

Front

What is the shortest day of the year?

Back

Winter Solstice: The winter solstice occurs around December 21st in the Northern Hemisphere, marking the shortest day and longest night of the year.

Front

Why does the Earth have seasons?

Back

Tilt of the Earth on its axis: The tilt of the Earth's axis (approximately 23.5 degrees) causes different parts of the Earth to receive varying amounts of sunlight throughout the year, resulting in the changing seasons.

If a primary consumer contains 1,000 kcal of energy, how much energy does the secondary consumer gain when it eats the primary consumer?

Back

100 kcal: According to the 10% rule in ecology, only about 10% of the energy from one trophic level is transferred to the next. Therefore, a secondary consumer would gain approximately 100 kcal from a primary consumer containing 1,000 kcal.

Front

What is the greenhouse effect?

Back

Greenhouse Effect: The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space. This effect is essential for maintaining the planet's temperature.

Front

What are the main greenhouse gases?

Back

Main Greenhouse Gases: The primary greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor (H2O). These gases contribute to global warming.

Front

What is the difference between weather and climate?

Back

Weather vs. Climate: Weather refers to the short-term atmospheric conditions in a specific place at a specific time, while climate is the long-term average of weather patterns in a region over an extended period.

Front

What is biodiversity?

Back

Biodiversity: Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

Front

What is an ecological footprint?

Back

Ecological Footprint: An ecological footprint measures the environmental impact of an individual, community, or organization, expressed as the amount of land and water area required to produce the resources consumed and absorb the waste generated.
