The North Atlantic Drift is a warm ocean current that originates in the Gulf Stream and flows northeastward along the coast of Western Europe. It brings warm water and mild air to the region, resulting in a temperate climate.

A convergence zone is a region of the ocean where warm and cold currents meet. This meeting of waters with different temperatures can result in the formation of clouds, precipitation, and strong winds.

The tropical zone is located between the Tropic of Cancer and the Tropic of Capricorn. It is characterized by hot and humid conditions throughout the year, with little seasonal variation in temperature.

Upwelling is the process by which cold, nutrient-rich water from the deep ocean rises to the surface. This process is often caused by wind-driven currents or changes in water density.

Deforestation, the clearing of forests, is a major contributor to the increase in greenhouse gases in the atmosphere. Trees absorb carbon dioxide, a greenhouse gas, during photosynthesis. When forests are cleared, this carbon dioxide is released into the atmosphere.

Climate is the long-term average of weather conditions in a particular area. It is influenced by factors such as latitude, altitude, distance from the ocean, and prevailing wind patterns.

The California Current is a cold ocean current that flows southward along the coast of California. It brings cold water and air to the region, resulting in the formation of fog along the coast.

Downwelling is the process by which warm water from the surface of the ocean sinks to the deep ocean. This process is often caused by changes in water density or wind-driven currents.

The polar zone is located at the Earth's poles. It is characterized by cold temperatures and long, dark winters. The polar zone is home to unique ecosystems adapted to the extreme cold.

A divergence zone is a region of the ocean where surface water moves away from the equator. This movement of water can result in the formation of currents, eddies, and upwelling.

Fossil fuel burning, particularly the burning of coal and oil, releases large amounts of carbon dioxide into the atmosphere. Carbon dioxide dissolves in seawater, forming carbonic acid, which leads to the acidification of the oceans.

Condensation is the process by which water vapor in the atmosphere condenses into liquid water. This process occurs when water vapor cools and loses energy.

The temperate zone is located between the tropics and the polar zones. It is characterized by moderate temperatures and distinct seasons. The temperate zone is home to a wide variety of ecosystems, including forests, grasslands, and deserts.

A convergence zone is a region of the ocean where surface water moves towards the equator. This movement of water can result in the formation of currents, eddies, and downwelling.

Industrial waste discharge, particularly the discharge of untreated or poorly treated wastewater, is a major contributor to the pollution of the oceans. Industrial waste can contain harmful chemicals, heavy metals, and other pollutants that can contaminate marine ecosystems.
