Resistance to flow
Viscosity
Geothermal heat pump is also known as ?
Geo-exchange system
Refers to the condition of the atmosphere at a particular location over a long period of time
Climate
What volcano considered at extinct volcano in the Philippines
Mt Apo
5 best description of a Volcano
Crater, magma chamber, lava/magma, ash bomb, cylindrical/cone shape
Eruptions are small to medium in volume and sporadic violence
Strombolian
What are the basic parts of geothermal power plant?
Steam, turbine, generator, injection well and cooling tower
Why places that is near of the oceans have moderate climate and places that are far from bodies of water have extremes climate?
Water absorbs heat slower tham the soil that makes the places moderate climate
What mountain climbers wear during summer when climbing a mountain?
Jackets hoods or for cold season
5 types of volcanic eruptions
1. Phreatic
2. Phreatomagmatic
3. Strombolian
4. Vulcanian
5. Plinian
Positive effects of volcanic eruption:
A. Abrasive, acidic and odorous ash fall
B. Breakdown and decomposition of rocks
C. Extremely hot lava
D. Manifestation of acid rain
B. Breakdown and decomposition of rocks
Geothermal power plants need water and heat from deep within the Earth but each of them operates differently. Which among these type of geothermal power plants is found in such areas where there is low temperature of water rising from the surface and use common liquids such as pentane and isobutane to spin the turbine due to their low boiling point?
BINARY CYCLE PLANT
What the you call the loops in ocean currents? What causes this effects?
Coriolis effect cause of revolution ond rotation of the earth
Relate the air pressure , temperature and altitude
Altitude is inversely proportional to air pressure and temperature while air pressure and temperature is directly proportional
How are volcanoes classified?
1. Based on shaped
2. Based on activity
3. Based on eruption
Supposed that you are in am area when volcano has recently erupted, what can you do to protect yourself from the ash falls?
Use googles and wear face mask or wet cloth
Geothermal power plants are used to generate geothermal energy to produce electricity. Arrange the steps of generating energy in chronological order.
A. The steam cools off in a cooling tower and condenses back to water
B. Hot water is pumped from deep underground through a well under high pressure
C. The cooled water is pumped back into the earth to begin the process again
D. When the water reaches the surface, the pressure is dropped, which causes the water to turn into steam
E. The steam spins a turbine, which is connected to a generator that produces electricity.
B, D, A , C, E
Why is that the tropic artic has a long night during winter solstice?
Because of the tilt of the earth and during winter solstice the sun rays directly heat the tropic capricorn that causes warm at the tropic antartic and cold in tropic arctic
The difference between wind ward and lee ward
Wind ward moist and warm air
Vegetative and has rain
Lee ward warm and dry air
No rains with rain shadow and only cactus and grasses
