Is salinity higher in deep water?
Typically, the salinity decreases from the surface ocean to deep waters is very small, from about 36 g/L (ppt) at the surface to 35 g/L (ppt) in the deep water, thus there is a very small density decrease with depth given a constant temperature. The salinity of seawater also affects it’s freezing point temperature.
What is the relationship between water temperature and density?
Temperature Affects Density When the water is heated, it expands, increasing in volume. This is represented by the increase in the size of the box from Fig. 2.2 A to 2.2 C. The warmer the water, the more space it takes up, and the lower its density.
What is the relationship between pressure and temperature?
The pressure of a given amount of gas is directly proportional to the temperature at a given volume. When the temperature of a system goes up, the pressure also goes up, and vice versa. The relationship between pressure and temperature of a gas is stated by the Gay-Lussac’s law.
Who discovered the relationship between pressure and temperature?
Joseph Gay-Lussac
What is the relationship between temperature and pressure in Earth’s atmosphere?
The density and, therefore, pressure of atmospheric gases are related to their temperature. As temperature increases, gas molecules move faster and occupy a greater volume. This reduces their density which, in turn, reduces their pressure. Warm gases in the atmosphere are less dense than cold gases in the atmosphere.
What do you understand by weather and climate class 7?
(i) The average weather taken over a long time is called climate. (ii) A place receives very little rainfall, and the temperature is high throughout the year, the climate of that place will be hot and dry. (iii) The two regions of the earth with extreme climatic conditions are polar region and tropical region.
What is the difference between weather and climate class 7?
Weather is day-to-day information of the changes in the atmospheric condition in any area. Climate is statistical weather information that provides information about the average weather condition of a particular place over a long period.
What are 3 differences between weather and climate?
Weather is the day-to-day state of the atmosphere, and its short-term variation in minutes to weeks. People generally think of weather as the combination of temperature, humidity, precipitation, cloudiness, visibility, and wind. Climate is the weather of a place averaged over a period of time, often 30 years.
What are three differences between weather and climate?
Weather is affected by temperature, pressure, humidity, cloudiness, wind, precipitation, rain, flooding, ice storms, etc. The climate is the long term observations of the atmospheric conditions at any location like humidity, temperature, the sunshine, wind, etc. The changes in climate take a longer time to change.
What are the similarities and differences between weather and climate?
The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere “behaves” over relatively long periods of time.
What are differences between weather and climate?
Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time.
What is the difference between weather and climate give an example of each?
Weather reflects short-term conditions of the atmosphere while climate is the average daily weather for an extended period of time at a certain location. Weather is what you see outside on any particular day. So, for example, it may be 75° degrees and sunny or it could be 20° degrees with heavy snow.
How do you teach weather?

How do you explain weather to a child?
Weather is what the sky and the air outside are like, such as cold and cloudy. The weather is more than just wind or rain, but also includes some stunning effects in the sky like rainbows, flashes of lightning, and sunsets.
How does the weather change?
Daily changes in the weather are due to winds and storms. Seasonal changes are due to the Earth revolving around the sun. What causes weather? These differences in temperature create a restless movement of air and water in great swirling currents to distribute heat energy from the Sun across the planet.
What are the five causes of weather?
The five factors that determine the weather of any land area are: the amount of solar energy received because of latitude; the area’s elevation or proximity to mountains; nearness to large bodies of water and relative temperatures of land and water; the number of such storm systems as cyclones, hurricanes, and …
What causes different weather?
These are temperature, atmospheric pressure, cloud formation, wind, humidity and rain. A small change to any of these conditions can create a different weather pattern. Every weather pattern has a knock-on effect, creating a ripple effect around the world.
