Ocean Warming - AP Environmental Science
- What is the impact of ocean warming on polar ecosystems?
- Threatens species and habitats. Ice-dependent species lose habitat and food sources.
- How does ocean warming alter marine food webs?
- Disrupts predator-prey relationships. Temperature changes affect species interactions.
- What is the effect of ocean warming on sea ice extent?
- Reduces sea ice extent. Warmer water melts ice from beneath.
- Identify a consequence of ocean warming on coastal ecosystems.
- Increased coastal erosion. Rising seas and storms damage coastal habitats.
- How does ocean warming affect the ocean's pH levels?
- Leads to ocean acidification. CO₂ absorption forms carbonic acid, lowering pH.
- How does ocean warming influence ocean currents?
- Alters the strength and direction of currents. Changes temperature gradients that drive currents.
- Which human activity contributes most to ocean warming?
- Burning fossil fuels. Releases CO₂ that drives ocean warming.
- What is the effect of ocean warming on marine biodiversity?
- Leads to loss of biodiversity. Species cannot adapt to rapid temperature changes.
- What role does ocean warming play in sea level rise?
- Contributes through thermal expansion and ice melt. Both thermal expansion and ice melt raise sea levels.
- Identify an adaptation strategy for marine species facing ocean warming.
- Migration to cooler waters. Species move to maintain optimal temperature ranges.
- What is the role of oceans in carbon dioxide absorption?
- Oceans absorb CO₂, acting as a carbon sink. Oceans store about 25% of atmospheric CO₂.
- What is ocean warming?
- Increase in ocean temperatures due to climate change. Caused by greenhouse gases trapping heat that oceans absorb.
- What is the effect of ocean warming on hurricane intensity?
- Increases hurricane intensity. Warmer water provides more energy for storms.
- What is the relationship between ocean warming and sea turtle nesting?
- Affects sand temperatures, influencing sex ratios. Temperature determines turtle sex during development.
- What impact does ocean warming have on marine species?
- Shifts in species distribution and habitat loss. Species migrate to cooler waters or face extinction.
- Identify a solution to address ocean warming.
- Implementing renewable energy sources. Reduces fossil fuel emissions that cause warming.
- What is the effect of ocean warming on ocean stratification?
- Increases stratification. Reduces vertical mixing of nutrients and oxygen.
- Identify one way ocean warming affects weather patterns.
- Increases the frequency and intensity of storms. Warm water provides more energy for storm formation.
- How does ocean warming influence ocean deoxygenation?
- Contributes to deoxygenation. Warm water holds less dissolved oxygen.
- How does ocean warming influence global heat distribution?
- Affects thermohaline circulation. Disrupts density-driven currents that distribute heat.
- What effect does ocean warming have on the Gulf Stream?
- Weakens the Gulf Stream. Disrupts temperature gradients that drive the current.
- How does ocean warming affect sea levels?
- Causes thermal expansion, raising sea levels. Warmer water expands, contributing ~50% of sea level rise.
- What is the effect of ocean warming on the Antarctic ice sheet?
- Accelerates ice sheet melting. Warm water melts ice shelves from below.
- How does ocean warming affect the El Niño phenomenon?
- Intensifies El Niño events. Stronger temperature gradients enhance the pattern.
- Identify a challenge posed by ocean warming for fisheries.
- Alters fish stock distribution. Fish populations shift to maintain optimal temperatures.
- How does ocean warming affect the frequency of marine heatwaves?
- Increases frequency and intensity. Warmer baseline temperatures enable more extreme events.
- How does ocean warming affect the albedo effect?
- Decreases albedo by reducing ice cover. Less ice means less solar reflection.
- How does ocean warming affect the thermocline?
- Deepens the thermocline. Stronger temperature gradient between surface and deep water.
- What is the effect of ocean warming on sea grass beds?
- Causes decline in sea grass health. Heat stress reduces photosynthesis and growth.
- What is the primary cause of ocean warming?
- Increase in greenhouse gas emissions. Greenhouse gases trap heat, warming oceans.
- What is the relationship between ocean warming and phytoplankton?
- Reduces phytoplankton productivity. Stratification limits nutrient mixing for phytoplankton.
- How does ocean warming impact the carbon cycle?
- Reduces ocean's carbon uptake capacity. Stratification and chemistry changes reduce CO₂ solubility.
- Which ecosystems are most vulnerable to ocean warming?
- Coral reefs and Arctic ecosystems. Temperature-sensitive ecosystems face rapid changes.
- What impact does ocean warming have on ocean salinity?
- Alters salinity patterns. Changes evaporation and precipitation patterns.
- How does ocean warming affect nutrient cycling?
- Disrupts nutrient availability. Stratification prevents nutrient upwelling.
- What is the impact of ocean warming on fish populations?
- Causes shifts in distribution and abundance. Fish migrate to maintain optimal temperatures.
- Identify the effect of ocean warming on coral reefs.
- Coral bleaching. Heat stress causes corals to expel symbiotic algae.
- What is the effect of ocean warming on the Arctic region?
- Accelerates ice melt. Warmer water melts ice from below.
- Which gas is most responsible for ocean warming?
- Carbon dioxide (CO₂). Primary greenhouse gas driving global warming.
- Identify a method to mitigate ocean warming.
- Reducing greenhouse gas emissions. Addresses the root cause of warming.
