ESS 2.4.3 [AHL] Natural Phenomena Affecting the Ecosystem
Learning Objectives Ocean Current The ocean conveyor belt, also known as the global thermohaline circulation, represents a large-scale system of ocean currents responsible for the movement of vast quantities of upper-ocean water and the transfer of energy through deep-sea circulation. This process is primarily driven by the formation and subsequent sinking of cold, saline water…

ESS 2.4.2 Shifting Biomes
Learning Objectives Global warming is leading to shifts in biomes The distribution of biomes is influenced by factors such as temperature, sunlight, and precipitation. An increase in CO2 and other greenhouse gases raises the average global temperature (Topic 6), which subsequently impacts rainfall patterns. These climatic changes, in turn, affect the distribution of biomes. Studying…

ESS 2.4.1 Climate and Biomes
Learning Objectives Part 1: Climate vs Weather Distinguishing Climate and Weather Part 2: Distribution of Biomes Biomes Tropical Rainforests Tropical rainforests experience constant high temperatures (around 26°C) and heavy rainfall (over 2500 mm per year), creating ideal conditions for plant growth. Found near the equator between the Tropics of Cancer and Capricorn (23.5° N and…
