How do ocean currents affect climate quizlet?
Currents affect climate by moving cold and warm water around the globe. A surface current warms or cools the air above it, influencing the climate of the land near the coast.
How do ocean currents influence climate in the coastal areas?
Warm and cold ocean currents can affect the climate of coastal regions, but only when local winds blow in from the sea. Warm currents heat the air over the ocean and bring higher temperatures over land. Cold currents can lower air temperatures and can bring colder temperatures over land.
What effects do ocean currents have on short term climate change?
What effects do ocean currents have on short-term climate change? Check all that apply. Ocean currents can carry warm water, which can raise the temperature of the air and land. Ocean currents can carry cold water, which can cool the air and land.
How do currents affect the temperature?
Currents affect the temperature directly. The warm currents raise and the cold currents lower the temperature of the neighbouring islands. The winds blowing over the cold current carry low temperature and have a cooling effect.
What causes ocean currents?
Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. These currents move water masses through the deep ocean —taking nutrients, oxygen, and heat with them.
What causes deep ocean currents?
In contrast to wind-driven surface currents, deep – ocean currents are caused by differences in water density. The process that creates deep currents is called thermohaline circulation—“thermo” referring to temperature and “haline” to saltiness.
What are the 5 major ocean currents?
There are five major ocean-wide gyres—the North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian Ocean gyres. Each is flanked by a strong and narrow “western boundary current,” and a weak and broad “eastern boundary current ” (Ross, 1995).
How do ocean currents influence climate in the coastal areas Class 7?
Answer: Ocean currents influence the climate and economic activities of coastal regions in the following ways: Warm currents raise the temperature along the coast, while cold currents drop the temperature along the coast.
What weather do warm ocean currents bring?
Warming temperatures transported by ocean currents can promote atmospheric instability and the potential for precipitation and storms. This is the case for air masses over the western boundary currents of the North Pacific and North Atlantic gyres, the Kuroshio and Gulf Stream, respectively.
What has the greatest influence on a Places climate?
The most important factors affecting climate are latitude, altitude, distance from the ocean and sea, orientation of mountain ranges toward prevailing winds, and the ocean current. Latitude is how far a place is north or south of the equator. Latitude affects climate in many ways.
What property of ocean water affects climate the most?
Large bodies of water, such as oceans, seas and large lakes, can affect the climate of an area. Water heats and cools more slowly than landmasses. Therefore, the coastal regions will stay cooler in summer and warmer in winter, thus creating a more moderate climate with a narrower temperature range.
How does relief affect climate?
Relief can influence the amount of precipitation an area receives. When air is forced to rise over a mountain range, it cools and the moisture within it condenses. Clouds form and produce rain. This type of rainfall is called orographic rainfall or relief rainfall.
What are the 3 types of ocean currents?
Types of Water Currents Surface Currents. Surface currents occur in the upper 400 meters of the ocean. Deep Water Currents. Deep water currents make up 90 percent of the ocean currents. Why Currents Are Important.
How do mountains affect climate?
Mountains can affect the climate of nearby lands. In some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. Much of airborne moisture falls as rain on the windward side of mountains.
Does elevation affect climate?
You will discover that at high altitude, there is cold and the opposite is experienced when you go deep down the sea. However, the reason elevation affects climate and temperature gets colder is this. As you go higher up, the atmosphere experiences less pressure.
