Question 1

THE DIFFERENT LAYERS OF THE EARTH’S ATMOSPHERE

Answer 1

• EXOSPHERE (10,000km)
  -THERMOSPHERE (690km)
  -MESOSPHERE (85km)
  -STRATOSPHERE (50km)
  -TROPOSPHERE (6-20km)

Question 2

WHAT MAKES THE EARTH SPECIAL

Answer 2

-BLANKET OF AIR THAT SURROUNDS THE EARTH
-ONLY PLANET THAT CAN SUSTAIN LIFE

Question 3

TROPOSPHERE

Answer 3

LAYER CLOSEST TO THE EARTH NEARLY ALL LIFE AND ALL WEATHER OCCUR IN THIS LAYER. THIS IS WHERE CLOUDS ARE LOCATED AND AIRPLANES FLY

Question 4

STRATOSPHERE

Answer 4

STARTS OUT AS A COLD LAYER HOWEVER THE OZONE WARMS UP THE UPPER REGION OFF THIS LAYER BY ABSORBING THE UV RAYS

Question 5

OZONE LAYER

Answer 5

A PROTECTIVE LAYER IN THE STRATOSPHERE THAT BLOCKS HARMFUL UV RAYS WITHOUT IT WE WOULD BURN UP IT ALLOWS GOOD SUN RAYS TO HEAT UP EARTH

Question 6

MESOSPHERE

Answer 6

IS THE MIDDLE LAYER IT’S THE COLDEST LAYER OF THE ATMOSPHERE THAT PROTECTS THE EARTH FROM METEOROIDS THE METEOROIDS USUALLY BURN UP IN THIS LAYER

Question 7

THERMOSPHERE

Answer 7

THE TEMPERATURE HERE IS VERY HIGH MORE THAN 2000 DEGREES FAHRENHEIT THE INTERNATIONAL SPACE STATION ORBITS EARTH IN THIS LAYER

Question 8

EXOSPHERE

Answer 8

THE FARTHEST LAYER EXTENDING FROM THE THERMOSPHERE INTO OUTER SPACE, THE LAYER IS COLD AS IT GRADUALLY BLENDS INTO THE OUTER SPACE

Question 9

IONOSPHERE

Answer 9

LOCATED WITHIN THE THERMOSPHERE

Question 10

MAGNETOSPHERE

Answer 10

FORMED BY THE EARTH’S MAGNETIC FIELDS IT PROTECTS THE ATMOSPHERE FROM BEING BLOWN AWAY BY SOLAR WINDS

Question 11

PROPERTIES OF WATER

Answer 11

• COHESION
  -ADHESION
  -CAPILLARY ACTION
  -HIGH SPECIFIC HEAT

Question 12

WATER IS POLAR WHAT IS POLAR?

Answer 12

AN UNEQUAL SHARING OF ELECTRONS LEADS TO UNEVEN DISTRIBUTION OF CHARGE. OXYGEN “ACTS” NEGATIVE. HYDROGEN “ACTS” POSITIVE

Question 13

PART OF A WATER MOLECULE

Answer 13

• OXYGEN (NEGATIVE)
  -HYDROGEN(POSITIVE)
  -POLAR COVALENT BOND

( CAUSES TAH WATER TO BE “POLAR” HOWEVER WATER IS NEUTRAL WITH A NET CHARGE OF ZERO)

Question 14

HYDROGEN BONDS EXISTS IN WATER

Answer 14

ONE HYDROGEN BOND IS WEAK BUT MANY HYDROGEN BONDS ARE STRONG

Question 15

COHESION

Answer 15

IS THE ATTRACTION BETWEEN PARTICLES OF THE SAME SUBSTANCE;
SURFACE TENSION AND SURFACE FILM (THEY ALLOW INSECTS TO WALK ON WATER)

Question 16

ADHESION

Answer 16

IS THE ATTRACTION BETWEEN TWO DIFFERENT SUBSTANCES. WATER WILL FORM HYDROGEN BONDS WITH OTHER SURFACES

Question 17

CAPILLARY ACTION

Answer 17

WATER MOLECULES WILL TOW EACH OTHER ALONG WHEN IN A THIN GLASS TUBE ALSO CAUSES TO ATTACH

Question 18

HIGH SPECIFIC HEAT

Answer 18

AMOUNT OF HEAT RESISTS TEN\MPERATURE CHANGE BOTH FOR HEATING AND COOLING CAN ABSORB LARGE AMOUNT OF HEAT WITH LITTLE CHANGE IN ACTUAL TEMPERATURE

Question 19

REMEMBER

Answer 19

WATER IS LESS DENSE THAN AS A SOLID

ICE IS LESSDENSE AS A SOLID THAN AS A LIQUID
(ICE FLOATS)

FROZEN WATER FORMS CRYSTAL LIKE LATTICE

Question 20

SOIL QUALITY

Answer 20

REFERS TO THE PHYSICAL-CHEMICAL AND BIOLOGICAL PROPERTIES OF SOIL

Question 21

SOIL HEALTH

Answer 21

ENCOMPASSES THE OVERALL FUNCTIONALITY AND RESILIENCE OF THE SOIL ECOSYSTEM

Question 22

INDICATORS FOR WATER QUALITY

Answer 22

-TURBIDITY
-DISSOLVED OXYGEN
-TEMPERATURE
-pH
- NITRATES AND PHOSPHATES
-BIOINDICATORS

Question 23

TURBIDITY

Answer 23

MEASURES THE CLARITY OF THE WATER

Question 24

DISSOLVED OXYGEN

Answer 24

AMOUNT OF DISSOLVED OXYGEN INA BODY OF WATER. BREATHED BY FISH AND OTHER AQUATIC ORGANISMS. WHEN THE AMOUNT OF OXYGEN DEPLETES THE EUTROPHICATION PROCESS

Question 25

TEMPERATURE

Answer 25

THE AMOUNT OF DISSOLVED WATER IS CONTROLLED BY TEMPERATURE COLD WATER HOLDS MORE OXYGEN THAN WARM WATER

Question 26

pH

Answer 26

IS THE MEASURE OF HOW MUCH ACID OR BASE A SUBSTANCE IS IF THE WATER'S pH IS LESS THAN 7 THE WATER HAS ACID PROPERTIES IF THE WATER'S pH IS MORE THAN 7 IT HAS BASE PROPERTIES IF THE WATER'S pH IS 7 TEHN IT IS NATURAL

Question 27

NITRATES AND PHOSPHATES

Answer 27

WHEN THE AMOUNT OF DISSOLVED NITRATE AND PHOSPHATES INCREASES THEY CAUSE WATER QUALITY PROBLEMS IT ALSO PROMOTES THE GROWTH OF ALGAE

Question 28

BIOINDICATORS

Answer 28

THE NUMBER AND VARIETY OF ORGANISMS LIVING IN A BODY OF WATER

Question 29

EXAMPLES OF BIONDICATORS

Answer 29

-MAYFLY -WATER PANNY -CADDIE FLY -GILLED SNAIL -RUME BEATLE

Question 30

AIR QUALITY

Answer 30

IS A MEASURE OF HOW CLEAR OR POLLUTED THE AIR IS

Question 31

2 MAIN CULPRITS OF POOR AIR QUALITY

Answer 31

-PARTICULATE MATTER/AIRBORNE PARTICLES -A GROUND-LEVEL OZONE

Question 32

PARTICULATE MATTER/AIRBORNE PARTICLES

Answer 32

INCLUDES DUST AIR AND SMOKE AND THEY CAN BE INHALED CAUSING SERIOUS HEALTH PROBLEMS

Question 33

GROUND LEVEL OZONE

Answer 33

IS A GAS. THE MAIN INGREDIENT IS SMOG. FORMS WHEN CERTAIN POLLUTANTS CHEMICALLY REACT IN THE PRESENCE OF HEAT AND SUNLIGHT

Question 34

AIR QUALITY INDEX

Answer 34

IT REPORTS THE DAILY AIR POLLUTION. IT TELLS YOU HOW CLEAN OR POLLUTED YOUR AIR IS.

Question 35

THE LONGEST RIVER IN THE PHILIPPINES IS?

Answer 35

CAGAYAN RIVER ALSO KNOWN AS RIOO GRANDE CAGAYAN

Question 36

WHAT RIVER IS USED FOR DOMESTIC POWER SUPPLY, IRRIGATION, AND POWER PRODUCTION

Answer 36

AGNO RIVER

Question 37
