*1st Semester Science Test

Front

What can organisms that are buried without decomposing transform into over millions of years?

Back

Fossil fuels are formed from organisms that are buried without decomposing over millions of years.

Front

What happens to the water in Cup A and Cup B after several days?

Back

In Cup A, the amount of water will remain the same due to the lid preventing evaporation. In Cup B, the amount of water will decrease due to evaporation.

Front

How do human activities impact the carbon cycle?

Back

Burning fossil fuels increases atmospheric CO2 levels, while planting trees can help absorb CO2, mitigating the impact.

Front

What is the Earth's outer layer consisting of rock, soil, minerals, and dust called?

Back

The outer layer is referred to as the Geosphere.

Front

What happens when ice cubes are added to a cup of hot coffee?

Back

The hot coffee transfers heat to the ice cubes, causing the coffee to cool down.

Front

What is evaporation in the water cycle?

Back

Evaporation is the process where water changes from liquid to gas, rising into the atmosphere.

Front

What is condensation in the water cycle?

Back

Condensation is the process where water vapor cools and changes back into liquid, forming clouds.

Front

What is the role of trees in the carbon cycle?

Back

Trees absorb CO2 from the atmosphere, helping to reduce greenhouse gases.

Front

What is the difference between the biosphere and geosphere?

Back

The biosphere includes all living organisms, while the geosphere refers to the Earth's solid outer layer.

Front

What is the significance of the water cycle?

Back

The water cycle is essential for distributing water across the planet, supporting all forms of life.
