What is the teacher trying to demonstrate in the Salt Water Investigation assigned to a 9th grade Earth Science class?

Back

Front

When the surface water in the ocean is warm, a storm moving across the water draws up heat energy from the water, just like a straw sucks up a liquid. This creates moisture in the air. If wind conditions are right, the storm becomes a hurricane. Hurricanes that move over warm water compared to ones that move over cool water will most likely

Back

Gain energy and become more powerful

Answer explanation

Hurricanes gain energy and become more powerful when moving over warm water, as they draw heat energy from the surface. This process enhances moisture and wind conditions, fueling the storm's intensity.

What characteristic makes a good index fossil? A useful index fossil must be distinctive or easily recognizable and abundant.

Back

Having a wide geographic distribution.

Answer explanation

A good index fossil should have a wide geographic distribution (D) to ensure it can be used to correlate strata across different regions. This characteristic allows for more accurate dating and correlation in the geologic time scale.

Which of the following reduces the amount of water in lakes and rivers? High ground water, Evaporation, Precipitation, Runoff

Back

Evaporation

Answer explanation

Evaporation is the process that converts liquid water from lakes and rivers into vapor, reducing the overall water levels. In contrast, high groundwater, precipitation, and runoff typically contribute to water levels.

Farmers that have fields that border a river often plant grass along the edge of the river in an effort to reduce which of the following?
Animal habitats, Farmland, Soil erosion, Biomass

Back

Soil erosion

Answer explanation

Farmers plant grass along river edges to reduce soil erosion. The grass roots help stabilize the soil, preventing it from washing away during floods or heavy rains, thus protecting the farmland and maintaining soil health.

Why did the teacher ask the science class to reduce the size of the grid they were using from 3 centimeters to 1 centimeter?

Back

It would enable them to be more precise in their measurements.

Answer explanation

The teacher asked to reduce the grid size to 1 centimeter to enhance measurement precision. Smaller intervals allow for more accurate calculations of the land mass area, leading to better experimental results.

Which of the following would be considered a problem of using solar power as the only source to provide electricity?
Solar power depends on a nonrenewable energy source,
Solar power requires very little maintenance,
Solar may provide too much heat to replace other forms of energy,
Solar produces less power in some types of weather

Back

Solar produces less power in some types of weather

Answer explanation

Solar power is less effective in cloudy or rainy weather, leading to reduced electricity generation. This variability makes it unreliable as the sole energy source compared to other forms of energy that can provide consistent power.

Which of the following observations is the best assumption after observing the rock layers in the picture below?
The area observed in the rock layers above has never been seismically active.
The area observed in the rock layers above were seismically active in the past but are now inactive.
The area observed in the rock layers above is seismically active now but was inactive in the past.
The area observed in the rock layers above always has been seismically active and continues to be seismically active.

Back

The area observed in the rock layers above always has been seismically active and continues to be seismically active.

Answer explanation

The correct choice indicates that the rock layers have always been seismically active, suggesting continuous geological processes. This is supported by the characteristics of the layers observed, which show signs of ongoing activity.
