crater

funnel shaped opening at the top of a volcano
bowl shaped depression at the top of the volcano where the vent is located

Caldera

formed when a part of the wall collapse following an explosive eruption

Slope

surface of which are end or side is at a higher level than another, a rising or falling surface

base

lowest part bottom or supporting layer of the volcano

Vent

opening where volcano materials are released

Conduit

passageway through which magma travels to reach earth’s surface

Fissure

Elongated fracture or crater on earth’s crust from which lava erupts

Flank

sides of a volcano or a mountain

magma chamber

Underground compartment where the magmam is stored

Stratovolcano

highly viscous or thick, slow moving lava, termed as composite cone volcano, small crater
explosive eruptions

Mayon volcano, mount fujiyama

give me 2 example of stratovolcano

Cinder cone volcano

also as scoria cone
formed by fluid lava that is ejected because of high pressure that builds up in the magma chamber
Short lived

Smith volcano, mojaru volcano

Give me 2 example of cinder cone volcano

Shield volcano

Loose and fluid lava that flows over each other
Low and broad, resembles warrior’s armored sheld or a giantic blob

Mt canlaon, mauna lao volcano

Give me 2 example of shield volcano

Active volcano

Exhibits volcanic activity such as rumbling, crater, glow, eruption, or earth quakes with the last 10,000 years

Mayon volcano, taal volcano

give me 2 example of active volcano

inactive volcano

No historial record of equption, eruption in the past 10,000 years

Mt balungao

Give me 1 example of inactive volcano

Extinct volcano

no record of eruption. they do not have a magma supply

Mt butay

give me 1example of extinct volcano

Hawaiian eruption

The lava flows around the area forming a shield volcano. most not explosive

eruption of basaltic lava

Strombolian eruption

Types of eruption

This is violent one. cinder cone

small explosions

Vulcanian eruption

this is more explosive than hawaiian and strombolian eruptions

Plinian eruption

this is most explosive type and dangerous type of eruption

mushroom

Soil fertility, geothermal energy, new landforms, tourism spot

Give me four positive effect of volcanic eruptions

Property damage, water pollution, air pollution, health hazards

give me four negative effects of volcanic eruptions

dormat

what is other term for inactive volcano?

Composite cone

What is the other term of stratovolcano

Scoria cone

what is the other term of cinder cone volcano?

volcanic eruption

occur when magma rises to the surface and erupts through a vent in the earth’s crust

Magma

Molten material that is stored under the earth’s surface

Lava

Molten material that has reached the earth’s surface through the volcanic vent

Igneous rocks

the lava is liquid at first, but it hardens and solidifies forming?

Basaltic

MAFIC high in iron magnesium but low in potassium and sodium
temeperature of 1000c to 1200c low viscosity

Andesitic

Intermediate low levels of iron, magmsium, calcium, potassium and sodium
temperature of 800c to 1000c intermediate viscosity

Rhyolitic

Felsic high potassium and sodium content but low in iron, magmsium, and calcium content
temperature 650c to 800c high viscosity

Give me top producers of geothermal power in order

Geothermal energy

heat stored coming from the earth’s interiors

this heart warms water which is trapped in rock formation beneath it’s surface

Geothermal power plant

use heat from deep inside the earth to produce steam and generate electricity

Geothermal heat pump

top heat close to the earth’s surface to heat water or provide heat for building

extracted, compressed, and circulated

It circylates fluid through underground pipes, where they absorb heat. this heat is then _______, _________, and ______ through

Step 1

give me step of - wells are drilled deep into the earth to pump steam or hot water on the surface

Step 2

give me step of when the water reaches the surface the drop in pressure causes the water to turn into steam

Step 3

Give me step of The steam spins a turbine , which is connected to generator that generates electricity

Step 4

Give me step of Cooling tower cools the steam which condenses back to water

Step 5

give me step of the cooled water is pumped back into the earth to begin the process again

Weather

tells you what to wear each day

day to day condition of earth’s atmosphere at a particular time and place

Climate

tells you what types of clothes to have in your closet

overall weather conditions over a long period of time

Latitude

measures the distance north or south of the equator

Spherical

Earth’s shape is?

north, south

give me 2 polar zone

Tropic of cancer, equator, tropic of capricorn

Give me 3 tropical zone

Arctic, antarctic

Give me 2 temperate zone

Tropical climate

near the equator, the climate here is always warm

Temperate climate

climate ranges from hot to cold, depending on the season

Polar climate

cold areas or regions when the sun’s rays strikes earth at a very long angle

Altitude

the distance above sea level

Ocean currents

the continuous and directional movement of ocean that flows in a definite path (loop)

Coriolis effect

The perceived change in the direction of the currents caused by earth’s rotation

Topography

describes the physical features of area of land such as mountain, hills, and other landforms

Precipitation

any liquid or frozen water that forms in the atmosphere and falls back to the earth

it comes in many forms like rain, sleet, and snow

Windward side

Cooler and wetter

the mountain faces the wind and receives warm and moist air

Leeward side

warmer and drier

the air that goes down the leeward slope has lost its moisture on the windward side resulting to warm air and low relative humidity

Latitude, altitude, ocean currents, distance from bodies of water, topography

Give me five factors affecting climate

High viscosity

What viscosity of stratovolcano

Low viscosity

What viscosity of shield volcano

Volcano

an elevated landform with an opening at the top called cater, from where lava, rock, fragments, steam, gases, ash, and heat are ejected

Lower the viscosity

Higher the temperature? the?
