4. Which event would be the most predictable one year in advance of the event? a hurricane in Florida
an earthquake in California
a volcanic eruption in Japan
an eclipse of the Sun

5. Which property was probably used to classify the substances below?

Group A
water
aluminum
water vapor

Group B
gasoline
ice
air

Group C
alcohol
iron
oxygen

chemical composition
specific heat
state (phase) of matter
abundance within the Earth

6. What is the density of a rock which has a mass of 35 grams and a volume of 7.0 cubic centimeters?
5.0 g/cm3
0.20 g/cm3
28 g/cm3
42 g/cm3

1. an eclipse of the Sun

2. state (phase) of matter

3. 5.0 g/cm3

Explanation:

1. Eclipse of the sun occurs when the planetary bodies align in such a way that causes the moon to block sunlight from reaching the Earth. The eclipse of the Sun will be the most predictable occurrence because it follows a pattern of occurrence. Eclipse of the sun occurs after a specific period of time, hence, based on this, scientists can predict that when it will occur next using its previous pattern of occurrence.

2. Considering the following groups: Group A: water, aluminum, water vapor

Group B: gasoline, ice, air

Group C: alcohol, iron, oxygen

One would realize that each constituent of each group exists in a particular state of matter. For example, in group B, gasoline is a liquid, ice is a solid while air is a gaseous mixture. Same applies for group A and C where water and alcohol are liquids, iron and aluminum are solids, while water vapor and oxygen are gases.

This shows that the STATE (PHASE) OF MATTER was the basis of classification.

3.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.
