Land and Water Affect Temperature - Geography for Kids
The quantitative relationship between heat transfer and temperature change . What is the temperature when the water and pan reach thermal equilibrium a short time later? Express the heat gained by the water in terms of the mass of the water, the Take-Home Experiment: Temperature Change of Land and Water. Thus, the temperature of the air in a given location can be greatly affected by the Because of water's ability to absorb heat, store it and release it later, the. Water vapor aloft affects land temperatures by affecting atmospheric radiation. Mechanisms proposed to explain land–ocean temperature contrast . The important difference is that the land-to-ocean heat transport term ΔA is not defined.
Darker materials absorb more radiation than lighter materials.
The Ocean and Temperature
Rougher and dryer materials absorb more radiation than smoother and wetter materials. If you have ever walked barefoot on a street or sidewalk you'll recall these are much hotter than the grass beside them.

This Activity can also be adapted to challenge older students to come up with their own experimental protocols to test some of these fundamental and important principles. As an extension, you can invite students to suggest various materials to test other than those specified here. Students will observe that soil both heats up and cools faster than water. Students will observe that different colors absorb different amounts of the Sun's radiation.
Vocabulary Differential Engage Provide temperature maps to each group of students see p. Allow time for them to study there maps and share observations with each other. Then ask each team to prepare generalizations they have gathered from the maps. Prompt them to "Discuss the different temperature patterns you observe.
Where are the highest temperature located? Where are the lowest temperatures located? Areas of rapid change in density are pycnoclines and areas of rapid change in salinity are haloclines.
Thermoclines occur a short distance offshore when the shallow surface water is heated by the sun, resulting in warm, less dense, water staying at the surface and the sinking of cold, dense water.3.1.6 Explain relationship between the properties of water and its uses
A seasonal thermocline is formed when surface water is cooled, and sinks to the bottom resulting in a mixing of the layers. The approaching cool weather impacts primary production in the euphotic zone by cooling the surface water and bringing phytoplankton with nutrients to the creatures below.
Shorter days and lower angles of sunlight limit the growth rate of the phytoplankton, which in turn limits the primary production and growth rate of organisms higher on the food chain. The waters turn from blue to green as the increase in the number of phytoplankton dissolving inorganic nutrients causes an increase in chlorophyll biomass. Herbivorous zooplankton biomass also begins to increase, providing food for an entire food web above that depend on the energy they provide.
During the summer, the phytoplankton absorb most of the dissolved inorganic nutrients from the surface waters and are consumed by the zooplankton, decreasing the rate of photosynthesis.

Vertical mixing ceases and phytoplankton, which remain in the upper layers, become nutrient-limited. The cycle starts all over in the fall when the surface water cools, churning the deeper, nutrient-rich waters into the depleted surface waters. Nutrients become available again and the phytoplankton blooms in great quantity during the spring after the intense winter mixing. Fall and summer are the least plentiful months due to the less active summer waters. The seasonal cycle of phytoplankton growth is an amazing demonstration of the complex and interwoven physical, chemical and biological processes of the ocean.
Sean Chamberlin has described this phenomenon in the following paragraph: This biological process known as phytoplankton photosynthesis affects a chemical process which is the concentration of inorganic nutrients. As photosynthesis proceeds, the concentration of inorganic nutrients diminishes. In an ironic twist of fate, the chemical processes the rate at which new inorganic nutrients are made available take over the biological processes rates of photosynthesis.
In another interplay of processes, we can also see how biological processes increases in chlorophyll, detritus, and bacteria, important components of light absorption affect a physical process the penetration of light into the water column. Geological processes such as the weathering of rocks are also involved as the ultimate source of all the nutrients in the sea, and thus, geology affects biology.
One of the oceans' and nature's most fascinating characteristics is the interplay between these processes and how a large stationary rock on land can affect a tiny floating microscopic plant in the ocean! Heat thermoand haline density are the two main factors determining the density of seawater.
As you may remember, temperature and density share an inverse relationship so when the surface currents i.

These currents resurface in the northeast Pacific Ocean 1, years later. Ocean water from all of the ocean basins mixes thoroughly, carrying heat energy and matter in the form of solids and gases, making Earth's ocean a global system. As you can see, the state of this thermohaline circulation, sometimes called the global conveyor belt, can have an enormous impact on the climate of our planet.
The System The deep ocean, devoid of wind, was assumed to be perfectly static by early oceanographers. However, it has been found with modern instrumentation that movement in deep water masses is frequent. In contrast to the wind over land, the major driving forces of ocean currents are differences in density and temperature.
The density of ocean water is not the same throughout and there are sharply defined boundaries between water masses which form at the surface of the ocean.
They are positioned one above or below each other according to their density.
