SG5 Activity 1

SG5 Activity 1In this experiment the water acts as an agent in the physical weathering of the rocks(polvoron). The vigorous shaking of the containers B and C represent the mechanical aspectof weathering. I believe container A acts as the control. Water is weathering agent that seepsthrough the polvoron and weakens it. A weakened polvoron is easy to erode as shown incontainer C. The same phenomena can be observed in nature. Water acts as a hydratingagent that weakens rocks making it easier for agents of erosion to breakdown rocks.

SG4 Activity 2

Below are the plates that make up the Philippine islands. There are subduction zones wherethe Eurasian plate meets the Manila plate and the Sulu plate which forms a discontinuous lineof active volcanoes from Taal to Iraya. To the East the subduction of the Philippine platecauses the line for volcanoes from Balut to Mayon.

Answers:

1. Wikipedia says gypsum is a soft sulfate mineral. It can be used as fertilizer or used amain constituent in blackboard chalk. A variety of gypsum is called alabaster which isused in sculptures.

2. Calcite, again from wikipedia is used in optics.3. Quartz is the one I’m most familiar with. It’s a silicate mineral. One of it’s uses is on

timekeeping—the quartz clock.4. Graphite is used in batteries, as lubricants and pencil lead.5. Talc is used in talcum powder.6. Magnetite is a source of iron. It’s the most magnetic of all naturally occurring magnetic

materials.

SG2 Activity 2

a.) From wikipedia:

1. Pacific plate2. North American plate3. Antarctic plate4. Eurasian plate5. African plate6. Australian plate7. South American plate8. Nazca plate9. Scotia plate

10. Arabian plate11. Indian plate

b.) The Philippines is in the Eurasian plate. The Eurasian plate is a continental plate.

SG1 Activity 3

The activity window is too small to read. I’m glad I managed.

SG1 Activity 2

Bulusan is in the southern tip of Luzon.

Mount Apo borders the Davao gulf to the northwest.

Sierra Madre runs along the eastern coast of Luzon.

I can’t locate the Rio Grande on the map but it should right in the middle of Mindanao.I would say the river systems flows around and radially outwards from the location ofvolcanoes.

SAQ 7-1

Plate tectonic movements. Uplift in particular.

SAQ 5-3

It exposes the rock to weathering.

SAQ 5-2

Natural and man made activities that break up the rocks. Natural chemical processes thatoccur on the earth’s surface like the formation of ice, acid rains etc.

SAQ 6-3

SAQ 6-2

The plate is moving northwest.

Based off the diagram below the igneous rock will be a) gabbro and the remaining melt willtend for form a) basalt.

There is the Manila, Negros, Sulu, Cotabato, and Philippine trench. There is also a transformfault/boundary between the East Luzon Trough the Philippine trench.

SAQ 4-1

The slab-pull model has something to do with gravity and the weight of the lithosphere. Twocontinental plates are of equal density and thus equal weight so the slab-pull model cannotexplain why they are drifting apart.

SAQ 3-1

Because oceanic rocks came from mid-ocean ridges, which is formed later than thecontinental rocks and are thus newer. As new rocks come from the ridges the old ones getspushed further away from the ocean floor and towards the continents.

SAQ 2-2

I think I already answered this one in the previous activity.

Activity 2-1

Ok this map is Metro Manila and the surrounding areas. I had to look at the comment for theactivity. Even though it asks only for a map of Metro Manila it discusses stream distributionsnot found in Metro Manila. There are noticeable radial patterns in the Bataan area. Sub-parallel patterns in Cavite and branching patterns in the NCR.

SAQ 2-1

I think the mountain ranges in the Philippines are volcanic. The Philippines sits in the PacificRing of Fire. Even the islands itself are made by volcanoes.

Activity 1-2

The raw material for plastics are petrochemicals which are found in petroleum commonlyknown as oil.

Activity 1-1

According to the DENR:

“Among our important metallic minerals found in abundance in various parts of the country include gold, copper, iron, chromite, nickel, cobalt and platinum, while our non-metallic resources include sand and gravel, limestone, marble, clay, and other quarry materials.”

Gold is used for jewellery and electronics. Copper in electronics. Iron in construction.Chromite is a source of iron. Nickel for electronics and coins. Cobalt for alloys and pigments.And lastly, platinum for electronics and chemical industry.

SAQ 1-1

Ans:

1. False. The Law of Uniformitarianism states that “The present is the key to the past.”2. False. The tempereture is too high for solid matter to exist right after the big bang.3. False. In our own solar system alone there 7 other planets revolving around the sun.

There are also exoplanets or extrasolar planets. Planets that revolve around otherstars.

4. True. They are elements with the simplest nuclei that are able to survive the intensity ofthe big bang.

5. True. It’s happening today and by the LoU it happened before.
