• The smaller the star the brighter it is.

• The size doesn’t affect its brightness.

Why were constellations important to ancient Filipino culture aside from their practical uses?

•    They inspired early calendars.

Which of the following is NOT a consequence of excessive carbon emissions?

•   Melting polar ice caps

•    Ocean acidification

   

• Improve agricultural productivity

Evaluate the correct description for classifying cone shape of a volcano.

•     Cinder cone shape like Iraya has the steepest slope compared to composite and shield shape volcanoes.

• Composite cone shape has the steepest slope and therefore are the tallest like Mayon, while the cinder has medium height and shield has the smallest.

• Cinder cone like Bud Dajo and composite like Pinatubo are the same in appearance but is different from composite shape Iraya.

• Shield cone shape like Taal has the widest crater and therefore the most destructive volcanoes compared to cinder and composite shape.

The higher the elevation or height of a volcano, the steeper the slope that can lead to more destructive magma emission.

• TRUE

• FALSE

The cone shape is not related to the elevation or height of the volcano, instead the number of eruptions determine the amount of magma emission.

• TRUE

• FALSE

What preparation should be made before a volcanic eruption?

• Know the location of the evacuation site and the fastest safest way to go there.

• Wear masks when cleaning

What preparation should be made DURING a volcanic eruption?

• Prepare your family's GO BAG containing items needed for survival

• When notified, immediately evacuate to safer grounds,

What preparations should be made AFTER a volcanic eruption?

• Leave the evacuation area only when authorities say it is safe

• Stay away from rivers and streams for possible lahar flow.
