Refer to the skotch below showing ocoan currents [Sourco: frooworldmaps.not] 4.1 Name the TWO ocean currents at 1 (east) and al 2 (west). 4.2 What is the ocean at which ocean current 1 is situated? 4.3 Describe the moisture content and the temperature of ocean current 4.4 Warm ocean currents flow from (equatorial polar) regions and the 1. cold ocean current flow along the (equatorial/polar) regions. 4.5 Account for the temperature variation between Port Nolloth and 4.6 Briefly explain the contribution of ocean current 1 and ocean current Durban. 2 on the weather of South Africa.

**4.1** - At position 1 (east): the **Agulhas Current** - At position 2 (west): the **Benguela Current** **4.2** The Agulhas Current (position 1) is situated in the **Indian Ocean**. **4.3** The Agulhas Current carries warm water that has a high moisture content. In other words, it transports water which is relatively warm and laden with moisture from tropical regions, thus influencing coastal climates. **4.4** Warm ocean currents flow from **equatorial** regions, whereas cold ocean currents flow from **polar** regions. **4.5** Port Nolloth, located on the west coast, is influenced by the cold Benguela Current. This current brings up cold, nutrient-rich water from deeper layers of the ocean (through upwelling), thereby lowering sea-surface temperatures. In contrast, regions on the east coast (e.g., Durban) are under the influence of the warm Agulhas Current, which raises sea and air temperatures. This difference in the temperatures of the influencing ocean currents accounts for the temperature variation between Port Nolloth and Durban. **4.6** - **Agulhas Current (Ocean Current 1):** By carrying warm, moist water from tropical regions, it contributes to milder, wetter conditions along the eastern and southern parts of South Africa. This current is associated with higher evaporation rates and increased humidity in the coastal regions, affecting rainfall and local weather patterns. - **Benguela Current (Ocean Current 2):** Flowing along the west coast, its cold, dry water results in cooler air temperatures and drier conditions. The upwelling associated with this current reinforces these cooler temperatures and also promotes high marine productivity, which in turn influences local weather and climate patterns differently from the east coast.
