Answer
Brief Explanations:
- a. Accuracy: In science, accuracy refers to how close a measurement is to the true or accepted value.
- b. Hypothesis: A hypothesis is a proposed explanation made on the basis of limited evidence as a starting - point for further investigation.
- c. Dependent variable: The dependent variable is the variable being tested and measured in an experiment, which depends on the independent variable.
- d. Independent variable: The independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable.
- e. Observation: Observation is the act of gathering information through the senses or with the help of instruments.
- f. Precision: Precision refers to how close repeated measurements are to each other.
For the identification of earth - science branches:
-
Clouds: Meteorology (M) as clouds are related to weather.
-
The moon: Astronomy (A) as the moon is a celestial body.
-
Seawater: Oceanography (O) as it deals with the oceans.
-
Weather forecaster: Meteorology (M) as weather forecasting is part of meteorology.
-
Solar system: Astronomy (A) as it is a collection of celestial bodies.
-
Rocks: Geology (G) as geology studies rocks.
-
Storms: Meteorology (M) as storms are weather - related phenomena.
-
Earthquakes: Geology (G) as they are related to the earth's crust.
-
3. Earth's shape: The Earth's shape is called a geoid.
-
4. Matter and energy cycles: The water cycle, carbon cycle, and nitrogen cycle are common matter and energy cycles.
-
5. Ultimate energy source for the Earth: The Sun is the ultimate source of energy for the Earth.
-
6. Percentage of Earth's surface covered by water: Approximately 71% of the Earth's surface is covered by water.
-
7. Carrying capacity: Carrying capacity is the maximum number of individuals of a species that an environment can support.
-
8. Composition of the asthenosphere: The asthenosphere is composed of semi - molten rock.
-
9. Process in plants to capture and transfer solar energy: Photosynthesis is the process by which plants capture and transfer solar energy.
-
10. First Law of Thermodynamics: The First Law of Thermodynamics states that energy cannot be created or destroyed, only transferred or converted from one form to another.
-
11. Lines of LATITUDE: Lines of LATITUDE run horizontally, are called parallels, and are used in locating places north & south of the equator.
-
12. Lines of LONGITUDE: Lines of LONGITUDE run vertically, are called meridians, and are used in locating places east & west of the prime meridian.
-
13. Degrees between North and South Pole: 180 degrees separate the North Pole from the South Pole.
Answer:
- a. Accuracy: How close a measurement is to the true value.
