25
another name for Composite volcanos
Stratovolcanoes
26
Formed when viscous andestic lava flows out of a vent for a very long time. They have acidic and sticky lava which allos the lava to solidify without travelling very far.
Composite
27
Cone is symmetrical. Explosive eruptions.
Composite
28
Formed when non-acidic basaltic lava flows of high viscosity producing broad sloping sides and shield-like structures.
Shield
29
Dome shaped with a wide base.
Shield
30
Classification of A Volcano According to Shape:
Cinder Cone, Composite, Shield
31
Classification of A Volcano According to Eruption:
Active, Dormant, Inactive/Extinct
32
These volcanoes have not had any eruption in the past 10 000 years and are expected not to erupt anymore in the future.
Extinct / Inactive
33
they have erupted at least once in the last past 10 000 years and are likely to erupt again
Active
34
active but not erupting; however they are expected to erupt anytime soon.
Dormant
35
Kinds of Eruptions Can be classified as either
effusive or explosive.
36
Involve the outpouring of basaltic magma that is relatively low in viscosity and low in gas content.
Effusive eruptions
37
involve magma of high viscosity and high gas content.
Explosive eruptions
38
Driven by steam due to rapid heating beneath a volcano.
Phreatic
39
Occurs when water interacts with magma.
Phreatomagmatic
40
Fountains of either basaltic or andesitic lava.
Strombolian
41
Steam, viscous lava, volcanic material that very quickly goes down.
Pelean
42
Tall eruptions that go up to 20km high. Short, explosive and violent.
Vulcanian
43
Most destructive and violent eruptions. Volcanic materials go more than 20km high and form an eruption column.
Plinian
44
the average weather condition prevailing in a given area over a longer period of time.
Cimate
45
refers to the day-to-day atmospheric conditions.
Weather
46
The distance from the equator.
Latitude
47
Refers to the wind direction a particular area or region experiences most frequently.
Prevailing Winds
48
Winds that blow east to west near the equator.
Trade Winds
49
These usually happen near the equator with light ocean currents and winds.
Doldrums
50
Subtropical latitudes found between 30° and 35°. Wind is usually weak.
Horse Latitudes
51
blow from west to east in middle latitudes
Westerlies
52
Dry, cold winds that blow from the high pressure of polar highs.
Polar Easterlies
53
Height above sea level.
Altitudes
54
Places near water tend to be cooler in summer and warmer during winter.
Distance from the Sea
55
Oceans and seas heat up and cool down faster than land.
Distance from the Sea
56
is best known for his climate classification scheme.
Wladmir Peter Koppen
57
He divided the world into ____ categories.
5
58
Places with hot summers and seldom rains or precipitation. Common to places or areas that are arid or semiarid.
Dry Climate
59
Found near or at the equator. Generally it has two seasons– dry and wet.
Tropical Climate
60
Characterized by moderate rainfall, warm summers, and cool winters.
Temperate Climate
61
includes a variation of temperature all-year round: hot summers, cold winters, and a small amount of rainfall.
Continental Climate
62
Cool summers and very long cold winters. A layer of permanently frozen ground called permafrost
Polar Climate
63
Refers to the climatic condition in localized areas near Earth’s surface.
Microclimate
64
They play a vital role in plant growth and regeneration.
Microclimate
65
The climate inside a building or an airplane as compared with that of the outside is called
crypto climate
66
There are_____microclimates in the Philippines.
4
67
There are two pronounced seasons. Dry from the months of November to April and wet the rest of the year.
Type I -
68
There is no dry season with very pronounced rainfall from November up to April and wet the rest of the year.
Type II
69
Seasons are not very pronounced. It is relatively dry from November to April then wet the rest of the year,
Type III
70
Rainfall is more likely to be evenly distributed throughout the year.
Type IV
71
is described as the change in average weather patterns that affect Earth’s regional and global climates.
Climate change
72
refers to the gradual increase of the overall temperature of Earth’s atmosphere.
Global Warming
73
is when the sun’s energy that reaches Earth’s atmosphere is being absorbed to warm the planet.
