What are the advantage and disadvantage of ocean currents?
Disadvantages – Sometimes there will not be a lot of waves (which means no energy), It could interfere with ocean ecosystems in the area of the currents, and the temperature is raised wherever ocean currents are happening (which could also ruin an ecosystem).
What are the advantages of ocean currents?
Ocean Currents and Climate Ocean currents, including the ocean conveyor belt, play a key role in determining how the ocean distributes heat energy throughout the planet, thereby regulating and stabilizing climate patterns.
What are the ocean currents Class 7?
Ocean currents. These are streams of water flowing constantly on the ocean surface in definite directions. The ocean currents may be warm such as the Gulf Stream and cold such as the Labrador Ocean current. The areas where the warm and cold currents meet provide the best fishing ground of the world.
What are ocean currents question answer?
Answer a: Water currents beyond the depth of 500 metres are known as deep water/ocean currents. These currents are formed due to the differences in temperature and density of the water in different parts of the ocean. This is known as thermohaline circulation. These currents flow till the sea-bed of the ocean.
What do you know about the ocean currents?
Ocean currents are driven by wind, water density differences, and tides. Oceanic currents describe the movement of water from one location to another. Currents are generally measured in meters per second or in knots (1 knot = 1.85 kilometers per hour or 1.15 miles per hour).
What are the important components of water cycle?
The water cycle consists of three major processes: evaporation, condensation, and precipitation. Evaporation is the process of a liquid’s surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor.
Why is the water cycle called a cycle?
The water cycle, also known as the hydrologic cycle, describes the continuous movement of water as it makes a circuit from the oceans to the atmosphere to the Earth and on again. Most of Earth’s water is in the oceans. The sun, which drives the water cycle, heats water in the oceans.
How does climate change affect our weather?
Scientific studies indicate that extreme weather events such as heat waves and large storms are likely to become more frequent or more intense with human-induced climate change. This chapter focuses on observed changes in temperature, precipitation, storms, floods, and droughts.
