Identify patterns of change in rock formations - 4th Grade Science

Card 0 of 10

Question

What patterns of change are noticeable in the graphic of the rock formation below?

Colorado River, Grand Canyon, Landscape

Answer

This is a graphic of a canyon, which is a type of rock formation. Changes can be noticed in the formation as it progresses upwards. The colors are light, almost gray color towards the bottom of the canyon closest to the water. The canyon is darker and burnt orange as it moves upwards. As the canyon changes in age, it also changes in colors. A canyon like the one pictured is an obvious way to see how the Earth has changed over the years.

Question

This is a graphic of sandstone on a beach that has been worn away over time by wind and water. What patterns are identifiable in this rock formation?

Rock, Sandstone, Washout, Nature, Shoreline, Beach

Answer

This sandstone on the beach shore demonstrates the patterns of change that can be seen in rock formations. The rock changes colors as it progresses; there are stripes of different oranges, tans, and reds. Some sections are covered in holes, and those parts are grey, black, and white. There are changes in textures throughout the rock formation. Some parts are smooth, and others are covered in holes. As rocks are weathered and eroded with wind and water over the years, there are visible changes to the formations and structure.

Question

Based on the table below, how do rock formations change?

Answer

This table shows the different layers of rocks, how they are formed, and what they are created from. What is noticeable about the changes in the rock layers is that each one is built from something different, has unique characteristics, and is formed in its ways. There are no two layers that are the same.

Question

Which graphic represents a rock formation that has changed through time?

Answer

The graphic that represents a rock formation that has changed over time must demonstrate different layers, weathered walls, a change in shape, and variation in colors. Only one photo matches this description and shows a rock formation that has changed.

Question

How does this photo represent patterns of change within a rock formation?

Answer

This photo is an excellent example of how rock formation change and there are patterns within the layers. The picture is separated into layers, and there are variations in the color, some segments have ledges, and the texture appears to change throughout the formation. The oldest layers at the bottom are similar in color and appearance, while the same can be said about the upper layers.

Question

How does the data table below demonstrate that rock formations change over time?

Screen shot 2020 09 08 at 8.56.19 am

Answer

This table shows the different layers of rocks, how they are formed, and what they are created from. What is noticeable about the changes in the rock layers is that each one is built from something different, has unique characteristics, and is formed in its ways. There are no two layers that are the same. Each layer is different, which demonstrates there is a change in the formation as well as the environment with the creation of each new layer.

Question

What patterns can be found between the two images of rock formations below?

Screen shot 2020 09 08 at 8.37.25 amScreen shot 2020 09 08 at 9.03.16 am

Answer

The graphics represent rock formations that have changed over time must demonstrate different layers, weathered walls, a change in shape, and variation in colors. When comparing the two rock formations, there are differences, but a pattern emerges that color variations, lines and grooves, and distinct layers are present in both formations.

Question

True or False: The photo below represents the natural process of weathering and erosion, creating a rock formation.

Screen shot 2020 09 08 at 9.12.17 am

Answer

A graphic that includes a rock formation that has changed over time must demonstrate different layers, weathered walls, a change in shape, variation in colors, and must be naturally occurring. This is a pile of rocks that has been stacked on each other by a human and is not naturally occurring through weathering and erosion.
