HB Science 7 Hydrologic Cycle

Categorize the descriptions to the correct form of energy transfer from the sun

Groups:

(a) Radiation

,

(b) Conduction

,

(c) Convection

• Rays or Waves Form

• hot air rises & cold air sinks

• transfers heat by touch

• transfers heat by circulation

• Warmer temps=faster atom movement

• DOES NOT need an atmosphere

• molecules bumping into each other

• can travel through EMPTY space

How does the Sun influence the Water Cycle?

• can cause water to change state from solid to liquid to gas

• can cause grass to complete more photosynthesis

• can cause clouds to spontaneously transform into Ozone

• can cause excessive fog to form within underground caves

Why is knowing the porosity and permeability of a soil important?

• helps you know where you can swim

• helps you know what the infiltration capacity will be in an area

• helps you know how much rain to expect in an area

• helps you know if gold or other precious minerals are in the area

Why is knowing the permeability and porosity of a soil important? Choose more than one

• good to know for crop managment

• good to know for where to construct a building

• good to know for erosion control

• good to know for flood risk management

• good to know for planning irrigation routes

Sandy soils tend to be HIGHLY PERMEABLE- this means that

• water flows through them easily

• water DOES NOT flow easily

• it would be a good soil to build a pond

• it is a difficult soil to clean

Porosity refers to

• how rocky the soil is

• how much fertilizer is available in the soil

• how much empty space there is in the soil

• how much clay is present

A Loam soil is a mix of what types of soil?(choose more than one)

• sand

• silt

• clay

• gravel

• clouds

Soils high in clay tend to have very low permeability and porosity due

• the clay particles leaving LARGE gaps that block the water

• the clay washing away due to erosion

• the clay particles being so small that they compact and leave hardly any space

• all choices
