Use the information about melting icebergs and your science knowledge. Melting Icebergs

Icebergs often form when large pieces of ice from land-based ice sheets and glaciers break off into the surrounding ocean water. These icebergs can have many shapes and sizes, ranging from only sixteen feet across to as wide as a small country. The number of icebergs in an ocean at any one time also varies. Scientists studying icebergs have observed that smaller icebergs melt at different rates than larger icebergs.

A group of students designed a classroom investigation to study the melting process for ice pieces of different sizes. They will use their results to build a model explaining why icebergs with different sizes melt at different rates.

For the experiment, the students started with an ice block that had the same total mass of ice as several ice cubes. The students placed the ice block and ice cubes in separate containers with water. The water in both containers started at the same temperature. They then measured the amount of time needed for the large block of ice and several smaller ice cubes to melt. The experiment setup for the ice baths is shown in Figure 1. The date in the table shows the starting conditions of the experiment just as the ice was added to the water.

Question
The students observed that the smaller ice cubes in Ice Bath 2 melted faster than the larger ice block in Ice Bath 1.

Based on the ice bath setup in Figure 1, which statement best explains why several smaller ice cubes melt faster than a larger block of ice?

A Small ice cubes have more surface area in contact with the liquid water, so more thermal energy is transferred from the water to the ice. Small ice cubes have more surface area in contact with the liquid water, so more thermal energy is transferred from the water to the ice.

B Smaller ice cubes have more surface area in contact with the liquid water, so more thermal energy is transferred from the ice to the water. Smaller ice cubes have more surface area in contact with the liquid water, so more thermal energy is transferred from the ice to the water.

C A larger ice block has more surface area in contact with the liquid water, so less thermal energy is transferred from the ice to the water. A larger ice block has more surface area in contact with the liquid water, so less thermal energy is transferred from the ice to the water.

D A larger ice block has more surface area in contact with the liquid water, so less thermal energy is transferred from the water to the ice. A larger ice block has more surface area in contact with the liquid water, so less thermal energy is transferred from the water to the ice.

The earth's moon is unusually large. two popular theories of the moon's origin include the "sister world" hypothesis, which states that the moon formed from the same materials as the earth, near enough to the earth that they fell into orbit around each other. a second theory is the "capture" hypothesis, in which the moon formed elsewhere in the solar system, and the earth's gravity pulled it into its orbit. studies of what the moon is made of indicate that some of its materials had to come from the earth or from the same area of the solar system where the earth had formed. at the same time, the moon does not contain much of the material that makes up the earth's core, so the moon could not have formed from the same materials as the earth. how do the two facts above affect the described theories of the moon's origin? a. they show that scientists will never agree on where the moon came from. b. they show that more experiments on moon formation need to be done. c. they show that no theory accounts for the existence of the moon. d. they show that neither theory is complete and entirely correct.

Read these sentences from the text. near the equator, the tropics receive the most rain on a consistent basis. as a result, the fresh water falling into the ocean decrease the salinity of the surface water in that region. [. .] . . as the salt content of sea water increases, so does its density. what can you infer about how rain affects the density of surface water near the equator?
