Q2 Study Guide Earth Science

Which of the following is an example of mechanical weathering?

• Acid rain dissolving limestone

• Bacteria decomposing organic matter

• Chemical reactions causing rust on metal

• Freeze-thaw cycle breaking a rock

Answer explanation

malamang, yung ibang choices chemical weathering

Which process describes the change in mineral components and texture of rocks due to the effect of high temperature and pressure without melting?

• Deposition

• Erosion

• Metamorphism

• Deposition

Which type of weathering involves the physical disintegration of rocks without any chemical change?

• Acid

• Biological

• Hydrolysis

• Mechanical

Which of the following is NOT a method of transportation during erosion?

• Chemical Reactions

• Gravity

• Ice

• Wind

Answer explanation

diba yung gravity, ice at wind kayang ilipat yung mga sediments sa ibang lugar? o anong kinalaman ng chemical reactions?

When the sediment is transported by a river and deposited in a traingular-shaped area where the river meets a larger body of water, what landform is a typically formed?

• Estuary

• Island

• Peninsula

• Sinkhole

Answer explanation

Kahit di mo alam kung ano yung estuary, dapat alam mo na di yan Island, peninsula at sinkhole.

Which of the following factors does NOT influence the occurrence of mass wasting?

• Amount of vegetation cover

• Earthquake activity

• Slope steepness

• Temperature

Answer explanation

Amount of vegetation: o syempre, mas maraming halaman mas safe.

Earthquake: syempre pag gumalgal ang maglalandslide

Slope steepness: Syempre mas matarik mas maglalandslide

o ano ngayon kinalaman ng temperature?

What type of mass wasting involves the rapid downslope movement of a block or blocks of rock along a discrete plane or surface?

• Creep

• Mudflow

• Rockslide

• Solifluction

Answer explanation

Kahit grade 2 alam na pag nagslide ang rocks... rockslide ang tawag dun!

What is the primary source of heat in the Earth's interior?

• Friction from plate tectonics

• Geothermal energy

• Radioactive decay

• Solar radiation

Answer explanation

Tinuro ko yan!

What is the main mechanism responsible for the transfer of heat from the Earth's interior to the surface?

• Advection

• Convection

• Conduction

• Radiation

Answer explanation

basta tandaan:

CONDUCTION: sa solid lang yan mga bhie
RADIATION: Di need ng medium or matter.
CONVECTION: pang liquid and gas yan. so dahil liquid ang mantle, makakatransfer ang heat from core to surface through convection
ADVECTION: ewan ko kung ano to.
