2nd nine weeks assessment 4th grade science practice

• As moving water is slows down, sediments are deposited over time

• Erosion from wind can carry sediments over thousands of miles

• Glaciers melting can cause sediments to be deposited in new places

• wind, water, and ice are the forces that can cause rocks to weather over time

Which of the following is an example of deposition

• Strong gusts of wind pick up sand and blast it against the rock

• Ocean waves carry away the sand from a beach changing it over time

• As a glacier melts, mounds of rocks and sediments are left behind.

• Snow melts and freezes inside the cracks of rocks over time pushing the rock apart

A science teacher set up the model below for her science class. Which of the following changes to Earth's surface does this model demonstrate?

• Weathering and erosion by a moving glacier

• Erosion and deposition by a flowing river

• Weathering and erosion by an earthquake

• Erosion and deposition by a tornado

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 changes slowly over time?

• A waterfall weathers and erodes jagged rocks making them smoother

• Flowing water erode sediments along the banks of a rive and deposits it when the water slows down

• Strong winds from a hurricane erode sand from one beach and deposit

• As a glacier flows, it carries large amount of rock and sediments from one place to another.

A fourth grade class examined the properties of soil during a lab investigation. Based on their observations What should students select as the properties of clay?

• Large Particles

• Very small particles

• Retains (keep) very little water

• Has a grainy texture

Students drew a path of earth around the sun and identified position 4 in their diagram below as summer since it s when Houston receives the most direct sunlight. Which season will Houston experience in 6 months after being in position 4?

• Spring

• Summer

• Fall

• Winter

Coal, Plastic, Propane, and Iron ore can be classified as which of the following groups?

• Energy Resource

• Renewable resources

• Nonrenewable Resources

• Earths Resources

Ms. Smith showed her class the objects shown below and asked them how many of the objects come from a nonrenewable resource

• 2

• 3

• 4

• 5

Mr. Logan's class were creating different mixtures. They created a data table to records the ingredients of each mixture. Which of the mixtures they created were solutions?

• Mixture 1 : Sand, gravel, water

• Mixture 2: sugar, salt, water

• Mixture 3: Salt, sand, toothpicks

• Water, oil, sand

A student illustrated the diagram below to show the pattern of change in the shadows on Earth. If the position of the sun moves toward the West, predict the change in the shadow's position. The shadow will-

• move towards the East

• move towards the west

• stay the same

• disappear
