Introduction: Students will gain an understanding for why people settle in certain locations and what geographical features lead to the development of civilizations. This two-day lesson focuses on water (fresh water in particular) as an essential resource. Geographic Connections: D2.Geo.2.3-5.
Whenever an object moves through water, it experiences the force of water resistance. Water resistance pushes objects back, making it hard for them to move through water. swimmer’s force water resistance Streamlined Shapes It is possible to reduce the effects of water and air resistance.
Water resistance is a type of force that uses friction to slow things down that are moving through water. It is often called drag. Water resistance doesn't have to be just water, however, it can happen to objects moving through any type of fluid. Water resistance happens because of the particles in water or the fluid.
When the water vapour cools down, it condenses and forms clouds. From there it may fall on the land or sea in the form of rain, snow or sleet. The process by which water continually changes its form and circulates between oceans, atmosphere and land is known as the water cycle (Fig 5.1). Our earth is like a terrarium.
Water Resistance and Upthrust: Teacher notes. LO: To understand the relationship between gravity and the upthrust of water. To know that water resistance is a type of friction, which is a force. To understand that water resistance can slow objects down in water.
The actual amount of the water vapour present in the atmosphere is known as the absolute humidity. It is the weight of water vapour per unit volume of air and is expressed in terms of grams per cubic metre. The ability of the air to hold water vapour depends entirely on its temperature.
Weathering, mass wasting, erosion and deposition are exogenic geomorphic processes. These exogenic processes are dealt with in detail in this chapter. Any exogenic element of nature (like water, ice, wind, etc.,) capable of acquiring and transporting earth materials can be called a geomorphic agent.
