Which statement best describes the processes of weathering and erosion?
Weathering and erosion are directly responsible for the breakdown of any type of rock into smaller particles and the carrying away of the loose sediments.
Weathering and erosion are directly responsible for depositing loose sediments on the bottom of the ocean, forming layers of sediment.
Weathering and erosion are directly responsible for the amount of water in a river that transports sediments to the sea.
Weathering and erosion are directly responsible for the transportation, deposition, and compaction of loose sediments on the seafloor.
A student stirs 15 grams of each substance listed below into 200 milliliters of water to form four different mixtures. The student then tries to separate the water from each mixture by pouring it through a kitchen tea strainer. Which mixture can the student separate most easily with the strainer?
salt and water
gravel and water
shampoo and water
sugar and water
A table lists the characteristics of four types of animals. What features do the ecosystems in which these animals live most likely have in common?
Dry, rocky mountains
Forests of pine trees
Tall, spiny cacti
Lakes and rivers
Aquatic plants have adaptations that help them live in water. For example, the structures needed for making food are located on the tops of floating plant leaves. This adaptation helps the plants —
absorb sunlight
stay anchored
avoid predators
capture fish
The circuit below does not work. Which procedure would most likely allow the bulb to light?
Open the switch and then connect the two wires that are attached to the wood block
Switch the positions of the two wires that are connected to the battery and then open the switch
Move the switch closer in the circuit to the battery
Connect the two wires that are attached to the woodblock
Woody plants have many different kinds of leaves. Some leaves have very smooth edges, while others have jagged edges, as shown in the diagram. The characteristics of plant leaves vary with the climate in which the plant naturally grows. Some scientists discovered an area with many fossilized leaves of woody plants. The scientists used data from samples of 100 leaf fossils to compare the number with smooth-edged leaves and the number of jagged-edged leaves. The scientists concluded that the plants had grown in a hot climate.
Which graph most likely represents the data from the investigation.
A student measured out 10 mL of four clear liquids and added one drop of a different-colored dye to each liquid. One of the liquids was water. The student then carefully poured each liquid into a graduated cylinder and let the mixture settle for 30 minutes. The student observed that the liquids had separated into layers, as shown in the diagram.
Which of these procedures would help the student identify the layer of water?
Stir the liquids, let them settle, and then identify the bottom layer as water
Drop a piece of ice into the graduated cylinder, let the ice settle, and then identify the layer just above the ice as water
Add water to the graduated cylinder, let the mixture settle, and then identify the layer that increases in volume as water
Carefully pour each layer into separate plastic containers, place the containers in a freezer, and then identify the liquid that takes the longest to freeze as water
The picture shows a cumulonimbus cloud forming over an ocean. Which statement best explains how the sun and the ocean interact to form a cumulonimbus cloud?
Heat from the sun warms the ocean, causing water to evaporate. The water vapor then condenses to form a cumulonimbus cloud.
Heat from the sun causes clouds in the area to gather over the ocean and form one large cumulonimbus cloud.
Heat from the sun causes clouds in the area together over the ocean and form one large cumulonimbus cloud.
Light from the sun causes ocean water to reflect water vapor into the air and gather over the ocean into a cumulonimbus cloud.
A partial food web from the Texas Piney Woods is shown. How many types of organisms in this food web obtain energy directly form the producers?
Two
Three
Four
Five
A science class has an aquarium in which fish and aquatic plants are growing. How is carbon dioxide directly involved in the survival of organisms in the aquarium?
The fish must absorb carbon dioxide through their gills for energy.
Both the plants and the fish need carbon dioxide to make their own nutrients.
The plants need carbon dioxide to make sugar for photosynthesis.
The plants release carbon dioxide into the water to control the water temperature.
(a) the process of rock breaking down into smaller pieces due to wind or moving water
uplift
rock formation
metamorphic rock
What is the main function of the roots in most plants?
To perform photosynthesis
To absorb water and nutrients
To attract pollinators
To produce flowers
Earth rotates on its axis once every (a) and explain how that causes the (b) cycle and the appearance of the Sun moving across the sky, resulting in changes in (c) positions and shapes.
Match the word to the definition.
Weathering
Breaks down rock into smaller pieces
Erosion
Carries sediment to new locations
Deposition
Sediment settles to the bottom of rivers
Compaction
Layers become headed and pressed
Cementation
Sediments and minerals harden into rock
