Observe the diagram below of how a rock changes over time.
Based on your knowledge and observation, which statement best describes what caused the rock to change?
weathering from water freezing and thawing over time
erosion from wind blowing over time
deposition from a glacier after it has melted
deposition from running water slowing down over time
A canyon is a deep, narrow valley with steep sides. Observe the picture of the canyon below.
Which statement below best explains how a canyon is changed slowly over time?
weathering and erosion by moving ice and wind
weathering and erosion by moving water and wind
erosion and deposition by moving wind and lava
erosion and deposition by moving water and ice
A science teacher set up the model for her science class.
Which of the following changes to Earth's surface does this model demonstrate?
erosion and deposition by a moving glacier
weathering and erosion by a flowing river
weathering and erosion by an earthquake
erosion and deposition by hurricane
Students made some observations of how the forces of wind, water, and ice have changed Earth's surface over time. Which of the following is NOT an observation of how the Earth's surface changes slowly over time.
water weathers and erodes rocks below Earth's surface creating underground caves
flowing water erodes sediments along the banks of a river and deposits it at the mouth creating a delta
strong winds from a hurricane erode and deposit sand from one location of a beach to another location
as a glacier melts, it deposits the large amounts of sediments it was carrying and reveals a wide valley
Students examined soil during a lab investigation. they listed properties of clay in their interactive notebook shown below
Properties of Clay
1. Sticky when wet
2. Reddish in color
3. Large particles
4. Retains lots of water
All of the following properties of clay were listed correctly EXCEPT --
retains lots of water
Large particles
Reddish in color
Sticky when wet
A fourth grade class recorded some properties of soil in the chart shown after conducting an investigation. The students added 100 mL of water to each soil sample. The soil that retains the most water is --
clay
silt
sand
top soil (loam)
Students drew the path of Earth around the sun and identified position 4 in their diagram as summer since it is when Houston receives the most direct sunlight.
Which season will Houston experience in 6 months after being in position 4?
spring
summer
winter
fall
A student illustrated the diagram to show the pattern of change in the shadows of the Earth.
If the sun above appears to move towards the West, predict the change in the shadow's position.
The shadow moves to the East
The shadow moves to the West
The shadow moves to the North
The shadow stays the same
Which student's moon journal shows the correct pattern of the observable appearance of the moon during one month's time?
A student classified natural resources in the table below
Which of the following would be the best title for column 2 in the table above?
Energy Resources
Fossil Fuel Resources
Renewable Resources
Nonrenewable Resources
Natural resources are classified as renewable or nonrenewable. Which of the following resources are classified in the same category as natural gas?
air and water
plants and animals
water and plants
coal and oil
Students were making statements about renewable and nonrenewable resources.
Statements about Natural Resources:
1. Natural gas is burned to heat water
2. Running water turns a turbine to generate electricity
3. Gasoline is refined from crude oil
4. Wind is produced by the uneven heating of Earth's surface
Which of these statements made by the students describe renewable resources?
1 and 2
1 and 3
2 and 4
3 and 4
A student is measuring and testing the physical properties of an object. The student places the object on the table and moves a magnet close to the object. The student observes that the object moves toward the magnet. Based on the observation, the object most likely is a --
copper coin
glass bead
iron nail
rubber ball
Four different objects were placed in a graduated cylinder containing 16 mL of water. Each object was placed inside the graduated cylinder one at a time as shown below.
Which object has a volume of 5 mL?
nail
battery
glue
button
A student is comparing the ability of objects to sink or float in water. The student places each object in water to test if it will sink or float. He recorded his observations in the table. Based on the data in the chart, which of the following is the best conclusion?
the aluminum cube sinks and the wood block floats
the wood block sinks and the iron paper clip floats
the aluminum cube sinks and the iron paper clip floats
the cork stopper sinks and the wood block floats
