Extreme tidal events, known as spring tides, occur when there is an alignment of the gravitational forces of the sun and the moon. When the sun and moon's forces are perpendicular to each other, moderate neap tides develop. The nature of the three major types of tides is described in detail.

How can it be expressed in a mathematical model? Finally, describe the effect of an intense 1 hour storm on streamflow over 24 hours using a hydrograph. What factors control the rate of evaporation on a soil surface? Discuss the movement of water into soils.

Atmospheric circulation drives the movement of two ocean currents. Within each of the three ocean basins, the patterns of these currents are very similar. In each basin, the ocean currents form several closed circulation patterns known as gyres. A large gyre develops at the subtropics centered at about 30 degrees of latitude in the southern and Northern Hemisphere. In the northern Hemisphere, several smaller gyres develop with a center of rotation at 50 degrees. Similar patterns do not develop in the middle latitudes of the southern Hemisphere. In this area, ocean currents are not bound by continental masses. Ocean currents differ from each other by direction of flow, by speed of flow, and by relative temperature. The cyclical rise and fall of seawater is known as a tide. Tides develop because of gravitational interactions between the earth, sun, and moon. The timing of tidal cycles is related to the rotation of the earth on its axis and the revolution of the moon around the earth.

The dissolved constituents found in the ocean come from the transport of terrestrial salts in weathered sediments by leaching and dream stream runoff. Seawater is a mixture of water and various salts. Chlorine, sodium, magnesium, calcium, potassium, and sulfur account for 99 of the salts in seawater. The presence of salt in seawater allows ice to float on top. Seawater also contains small quantities of dissolved gases including: carbon dioxide, oxygen, and nitrogen. These gases enter the ocean from the atmosphere and from a variety of organic processes. Seawater changes its density with variations in temperature, salinity, and ocean depth. Seawater is least dense when it is frozen at the ocean surface and contains no salts. Highest seawater densities occur at the ocean floor.

On average, the depth of the world's oceans is about.9 kilometers. However, maximum depths can be greater than 11 kilometers. The distribution of land and ocean surfaces on the earth is not homogeneous. In the southern Hemisphere there is 4 times more ocean than land. Ratio between land and ocean is almost equal in the northern Hemisphere. Geographers recognize three major ocean basins: Pacific; Atlantic; and Indian. The water found in the ocean basins is primarily a byproduct of the lithospheric solidification plan of rock that occurred early in the earth's history. A second source of water is volcanic eruptions.

The top of groundwater is known as the water table. Groundwater also flows because of gravity to surface basins of water (oceans) located at lower elevations. The flow of water through a stream channel is commonly called streamflow or stream discharge. On many streams humans gauge streamflow because of the hazards that can result from too little or too much flow. Mechanical gauging devices record this information on a graph known as a hydrograph. In the online notes there is a representation of a hydrograph showing some of its typical features. Oceans cover most of the earth's surface.

This movement of water by capillary action generally creates a homogeneous concentration of water throughout the soil profile. Losses of water stop when the film of water around soil particles reaches.0002. Water held from the surface of the soil particles.0002 mm is essentially immobile and can only be completely removed with high temperatures (greater than 100 degrees Celsius). Within the soil system, several different forces influence the storage of water. Runoff is the surface flow of water to areas of lower elevation.

On the microscale, runoff can be seen written as a series of related events. At the global scale runoff flows from the landmasses to the oceans. The earths continents experience runoff because of the imbalance between precipitation and evaporation. Throughflow is the horizontal subsurface movement of water on continents. Rates of throughflow vary with soil type, slope gradient, and the concentration of water in the soil. Groundwater is the zone in the ground homework that is permanently saturated with water.

Instead, it evaporates from the vegetation surface directly back to the atmosphere. A portion of the intercepted water can travel from the leaves to the branches and then flow down to the ground via the plants stem. This phenomenon is called stemflow. Another portion of the precipitation may flow along the edge of the plant canopy to cause canopy drip. Both of the processes described above can increase the concentration of the water added to the soil at the base of the stem and around the edge of the plants canopy. Rain that falls through the vegetation, without being intercepted, is called throughfall.

Infiltration is the movement of water from precipitation into the soil layer. Infiltration varies both spatially and temporally due to a number of environmental factors. After a rain, infiltration can create a condition where the soil is completely full of water. This condition is, however, only short-lived as a portion of this water quickly drains (gravitational water) via the force exerted on the water by gravity. The portion that remains is called the field capacity. In the soil, field capacity represents a film of water coating all individual soil particles to a thickness.06. The soil water from.0002.06 mm (known as capillary water) can be removed from the soil through the processes of evaporation and transpiration. Both of these processes operate at the surface. Capillary action moves water from one area in the soil to replace losses in another area (biggest losses tend to be at the surface because of plant consumption and evaporation).

Agricultural scientists sometimes refer to two types of evapotranspiration: Actual evapotranspiration and Potential evapotranspiration. The growth of crops is a function of water supply. If crops experience drought, yields are reduced. Irrigation can supply crops with supplemental water. By determining both actual evapotranspiration and potential review evapotranspiration a farmer can calculate the irrigation water needs of their crops. The distribution of precipitation falling on the ground surface can be modified by the presence writing of vegetation. Vegetation in general, changes this distribution because of the fact that it intercepts some the falling rain. How much is intercepted is a function of the branching structure and leaf density of the vegetation. Some of the water that is intercepted never makes it to the ground surface.

The process of lake acidification by acidic pollutants is also discussed. Evaporation and transpiration are the two processes that move water from the earths surface to its atmosphere. Evaporation is movement of free water to the atmosphere as a gas. It requires large amounts of energy. Transpiration is the movement of water through a plant to the atmosphere. Scientists use the term evapotranspiration to describe both processes. In general, the following four factors control the amount of water entering the atmosphere via these two processes: energy availability; the humidity gradient away from the evaporating surface; the wind speed immediately reviser above the surface; and water availability.

masses to cause saturation. It is also controlled by the amount of water vapor held in the air, which is a function of air temperature. A figure is presented that illustrates global precipitation patterns. In certain locations on the earth, acid pollutants from the atmosphere are being deposited in dry and wet forms to the earths surface. Scientists generally call this process acid deposition. If the deposit is wet it can also be called acid precipitation. Normally, rain is slightly acidic. Acid precipitation, however, can have a pH as low.3. The formation of acid deposition in the atmosphere is explained in detail.

Water vapor in the atmosphere is commonly referred to as humidity. If liquid and solid forms of water can overcome atmospheric updrafts they can fall to the earth's surface as precipitation. The formation of ice crystals and water droplets occurs when the atmosphere is cooled to a temperature that causes condensation or deposition. Four processes that can cause atmospheric cooling are: orographic uplift; convectional uplift; air mass convergence; and radiative energy loss. Precipitation can be defined as any aqueous deposit, in liquid or solid form, that develops in a saturated atmospheric environment and generally falls from clouds. A number of different precipitation types have been classified by meteorologists including rain, freezing rain, snow, ice pellets, gpa snow pellets, and hail. Fog represents the saturation of air near the ground surface.

Summary of the hippie Chapter, hydrology is the science that studies the earth's water molecules and their movement through the hydrologic cycle. The earth and its various abiotic and biotic systems are greatly influence by water. Water is essential for life and plays an important role in atmospheric and lithospheric processes. The hydrologic cycle is used to model the storage and movement of water molecules between the biosphere, atmosphere, lithosphere and hydrosphere. Water is stored in the following reservoirs: atmosphere, oceans, lakes, rivers, glaciers, soils, snowfields, and groundwater. It moves from one reservoir to another by processes like: evaporation, condensation, precipitation, deposition, runoff, infiltration, sublimation, transpiration, and groundwater flow. Water molecules are stored in the atmosphere in all three states of matter.
