WHAT I DID:
I studied the meaning of Intertropical Convergence Zone.
WHAT I LEARNED: 
That The Intertropical Convergence Zone (ITCZ), known by sailors as the doldrums, is the area encircling the earth near the equator where the northeast and southeast trade winds come together.
I CAN APPLY MY LEARNINGS: 
by applying it in my daily activities. i will be aware on what's happening around me. I ca use it whenever ther's a bad weather.
TRIVIA:
Thunderstorms along the Intertropical Convergence Zone played a role in the loss of Air France Flight 447, which left Rio de Janeiro–GaleĆ£o International Airport on Sunday, May 31, 2009, at 7 p.m. (4:00 p.m. EDT) and had been expected to land at Paris's Charles de Gaulle Airport on Monday June 1, 2009, at 11:15 a.m.The aircraft crashed with no survivors while flying through a series of large ITCZ thunderstorms, and ice forming rapidly on airspeed sensors was the precipitating cause for the cascade of human errors which ultimately doomed the flight. Most aircraft flying these routes are able to avoid the larger convective cells without incident.

EARTHQUAKE

  • An earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth's crust that creates seismic waves.
  •  Types of earthquakes
    There are many different types of earthquakes: tectonic, volcanic, and explosion. The type of earthquake depends on the region where it occurs and the geological make-up of that region. The most common are tectonic earthquakes. These occur when rocks in the earth's crust break due to geological forces created by movement of tectonic plates. Another type,volcanic earthquakes, occur in conjunction with volcanic activity. Collapse earthquakes are small earthquakes in underground caverns and mines, and explosion earthquakes result from the explosion of nuclear and chemical devices. 
  • Earthquakes are caused by faulting, a sudden lateral or vertical movement of rock along a rupture (break) surface. 
  •  Focus of an earthquake is the earthquake's underground point of origin while  Epicenter is directly above the focus.
  •  Foreshocks are earthquakes which precede larger earthquakes in the same location. Aftershocks are smaller earthquakes which occur in the same general area during the days to years following a larger event or "mainshock", defined as within 1-2 fault lengths away and during the period of time before the background seismicity level has resumed.
  •  Magnitude is a measure of earthquake size and remains unchanged with distance from the earthquake. Intensity, however, describes the degree of shaking caused by an earthquake at a given place and decreases with distance from the earthquake epicentre.

TROPICAL DEPRESSION


What I did…
 I studied about the tropical depression, how do these occurs, and the effects of its existence.
What I learned…
Is that tropical depression has different results that really affect the people and nature.
I can apply my learnings…
 Whenever there’s a tropical depression, that I should be ready for its effects on us.
TRIVIA...
 A tropical cyclone is a rapidly-rotating storm system characterized by a low pressure center, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain. Tropical cyclones typically form over large bodies of relatively warm water. They derive their energy from the evaporation of water from the ocean surface, which ultimately recondenses into clouds and rain when moist air rises and cools to saturation. This energy source differs from that of mid-latitude cyclonic storms, such as nor'easters and European windstorms, which are fueled primarily by horizontal temperature contrasts.
