Knowledge of Processes That Shape the Earth Grade 5 NGSS Standard: 5-ESS2-1 Develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact. Presenter: Dr. Persin

Air mass- a large volume of air with the same temperature and humidity. Types of Air Masses:  Continental Arctic (cA)  Maritime Polar (mP)  Continental Polar (cP)  Maritime Tropical (mT)  Continental Tropical (cT) They determine the weather in each region.

Wind patterns are known as the “general circulation.” Determine the surface winds of each hemisphere. Divided into three wind belts: Easterlies Westerlies Trade Winds

Clouds- A cloud is a large collection of tiny droplets of water or ice crystals. The droplets are so small and light that they can float in the air.  MOST COMMON TYPES of CLOUDS Cirrus Clouds Stratus Clouds Cumulus Clouds

CLOUDS in the TROPOSPHERE

Storms A storm is a large cumulonimbus cloud with lightning and thunder. It can produce gusty winds, heavy rain, and hail.

The Water Cycle Fast Fact: Life on Earth depends on the Water Cycle.

Land and Water Interactions Excess water, from rain, snowmelt or other sources flows over the land. Soil absorption- When water falls on land, it can seep into the ground. Surface runoff- the water flow which occurs when soil is saturated.

Land and Water Interactions Leaching- the loss of water soluble plant nutrients from the soil due to rain and irrigation. Sink holes-  a natural depression or hole caused by the removal of soil and/or bedrock, by water.

Land and Water Interactions Aquifer - an underground source of water bounded by impermeable rock or other materials (gravel, sand, silt, or clay). The groundwater can be usefully extracted using a water well.

Land and Water Interactions Reservoir- an artificial lake used to store water. They are often created by building a sturdy dam, usually out of concrete, earth, rock, or a mixture across a river or stream. Once the dam is completed, the stream  fills the reservoir.
