CA Science Test Practice Test Part 1

Part A: Students used a computer simulation to find out the variables that affect the gravitational force between two objects. They collected the data shown on the image. Click the image to see closely.

Choose the claim statement that best agrees with the data.

• Mass does not affect the gravitational force between two objects.

• Mass is the only variable that affects the gravitational force between two objects.

• Distance is the only variable that affects the gravitational force between two objects.

• Both mass and distance are variables that affect the gravitational force between two objects.

• Releases CO2 into the atmosphere through respiration.

• Use CO2 in photosynthesis.

• Produce O2 that is used in cellular respiration.

• Use O2 in cellular respiration.

In June 1991, Mount Pinatubo in the Philippines erupted. The eruption released large amounts of gases, such as sulfur dioxide, water vapor, and carbon dioxide, into the atmosphere. Sulfur dioxide reacted with water to form aerosol particles, and an aerosol cloud formed that covered a large portion of Earth.

Students want to determine what effect the eruption had on the global climate. Which question should the students investigate to BEST determine the effect?

• What was the temperature of the lava that flowed onto Earth's surface when Mount Pinatubo erupted?

• Was the amount of rain that fell on Mount Pinatubo in the days after the eruption greater or less than average?

• Do aerosol (gas) particles of this type cause the amount of solar energy that reaches the Earth's surface to increase or decrease?

• How did the temperature of the gases as they were ejected from Mount Pinatubo compare to the temperature of the gases ejected from other volcanoes?

A scientist measures the amplitude and wavelength of waves in the ocean. The scientist also calculates the amount of energy contained in one square meter of water for each wave. The data and calculations for four different waves are shown in the image table.

Which wave characteristics, if any, does the energy in the wave depend on?

• the amplitude only.

• the wavelength only.

• both the amplitude and the wavelength.

• neither the amplitude and the wavelength.

PART A: A 6th-grade student uses wax crayons to model different parts of the rock cycle. The model has several steps shown. Click the image and choose the correct order of the processes from top to bottom.

• weathering and erosion of igneous rock --> formation of sedimentary rock --> formation of metamorphic rock--> metamorphic rock changing to magma --> magma or lava forming igneous rock.

• formation of sedimentary rock --> formation of metamorphic rock--> metamorphic rock changing to magma --> magma or lava forming igneous rock --> weathering and erosion of igneous rock

• formation of metamorphic rock the formation of sedimentary rock --> metamorphic rock changing to magma --> magma or lava forming igneous rock --> weathering and erosion of igneous rock

• magma or lava forming igneous rock--> formation of metamorphic rock the formation of sedimentary rock --> metamorphic rock changing to magma --> weathering and erosion of igneous rock

Part B: The rock cycle is different from the 6th-grade student's model because the rock cycle...

• processes take a much longer time.

• the pressure is involved in some processes.

• there are both liquid and solid materials.

• thermal energy is needed for some processes.
