True or False: The marine fossils pictured below were found in an inland desert. This proves that the environment has changed over time.

True or False: The marine fossils pictured below were found in an inland desert. This proves that the environment has changed over time.
Fossils are a good representation of what the environment was at the time the organism died. If these fossils are of marine creatures, that means they were living in an area that was underwater or near the water. The site is currently described as an inland desert, so the environment has changed over time, making the statement correct.

Mrs. Elsa claims that the graphic shown below demonstrates a change in the rock layers. She says that they should be lined up with the same color in each row but there has been a shift.
Which natural disaster could cause this change in rock layers that would support Mrs. Elsa's claim?

Mrs. Elsa claims that the graphic shown below demonstrates a change in the rock layers. She says that they should be lined up with the same color in each row but there has been a shift.
Which natural disaster could cause this change in rock layers that would support Mrs. Elsa's claim?
Mrs. Elsa is correct, and the graphic supports her claim. The rock layers should be lined up where the same colors are next to each other, but there has been a shift in the layers caused by an earthquake. When an earthquake shakes the rock formations, the layers are shifted, and there is a disruption in their pattern. This cannot be reversed. It provides scientists with evidence that there was once an earthquake in this area and gives them useful information.

These fossils were found in the Earth's layer made of what type of rock?
.
These are fossils of shells leftover from aquatic creatures, so they would be found in the marine (water) animal layer. They would not be found where land animals lived or in areas of magma or volcanic ash. There are changes in fossils depending on their location and which Earth layer they are located in.

What factors affect how landscapes change?
What factors affect how landscapes change?
Many factors go into changing a landscape, and some will accelerate the process while others will slow it down. Moisture, human activity, and temperature are all factors that will affect how a landscape changes or is formed. Regularly being beaten down by the wind, water, the hot sun, frigid temperatures, and human construction will change the landscape. As water rushes through the base of a canyon, it is breaking apart the rock and moving it. Sand striking the cliffs on a shoreline will tear it apart grain by grain. Water seeping into rocks and then freezing and unfreezing will eventually break the rocks apart. These factors make changes to the landscape.

The photo that Tara selects for evidence must support the idea that landscapes have changed over millions of years. Two of the images show rocks of different colors or sizes, but they are not showing how the landscape has changed. The photo of the forest does not include rock layers or rock formations. The correct picture is from Switzerland and shows large rock formations that have been worn away by years of weathering and erosion.

What does the term landscape mean? Example: There are changes in the landscape throughout the years due to weathering and erosion.
What does the term landscape mean? Example: There are changes in the landscape throughout the years due to weathering and erosion.
The term landscape is used in science to describe the visible features of an area. If someone were standing on the edge of a canyon, they could explain the scene in terms of appearance, texture, color, relative size, landmarks, etc.. If it is something underground or hidden within a structure, it is not considered to be part of the landscape.

How are landscape changes recorded by layers of rocks and fossils?
How are landscape changes recorded by layers of rocks and fossils?
Layers of rock and fossils are like diaries of how the landscape has changed over time. Each layer contains information about the conditions and the scene at that time. Researchers can analyze the age of the rock and build a picture of what it looked like during that stage. Fossils help scientists to know what living things were in the area at the time and whether there were changes in water levels and weather conditions.

Fossils and rock layers can explain the changes in landscapes over time.
The statement is true. Scientists know that landscapes have changed over the years due to the information collected regarding rock formations, layers, and fossils. Looking at the type of plants or animals in the layers can tell us approximately how long ago they lived. The rock formations can show researchers how the wind and water have battered the area over the year and broken the rocks down. Rock layers and fossils are vital to learning about landscapes.

Jihoon claims that changes to a landscape are only visible above ground. Elicia tells Jihoon that he is wrong because we can see changes to landscapes both above and below ground. Which of the following statements is the BEST support for Elicia’s thinking?

Jihoon claims that changes to a landscape are only visible above ground. Elicia tells Jihoon that he is wrong because we can see changes to landscapes both above and below ground. Which of the following statements is the BEST support for Elicia’s thinking?
Changes to landscapes are most commonly viewed above ground; however, they are also visible underground. As shown in the picture, changes can be seen underground in the form of rocky trenches caused by tectonic plate movement, altering the topography of the ocean floor. Another way changes to landscapes can be observed underground is by studying caves and their slowly growing stalagmites, sinkholes, and shifts in their soluble rocks.

Erosion does not contribute to changes in the Earth’s landscape.

Erosion does not contribute to changes in the Earth’s landscape.
Erosion causes the removal of rock, soil, and dissolved material from one location, resulting in it being transported to a new location. Erosion can cause bits of existing structures to chip away over time, creating new structures in different places where the sediment is transported. Examples of erosion changing the landscape include caves, cracks in rocks, and riverbanks.

Read the following excerpt about rock formations in Zion National Park:
“Zion has spectacular geology. The arid climate and sparse vegetation expose bare rock and reveal the park’s geologic history. Evidence of deposition (sedimentation), lithification, uplift, weathering, erosion, tectonics, and volcanic activity make the park a showcase for changing landscapes. Volcanic vents, created as a result of the weakening of the Earth’s crust during tectonic events, allowed lava flows and cinder cones to form. Cinder was piled several hundred feet high in classic cone shapes, and lava flowed into valleys. Cinder cones and black basalt flows are visible west of Rockville and on the Kolob Terrace.”

Fossils are evidence of changes to Earth’s landscape.

Fossils are evidence of changes to Earth’s landscape.
Most fossils are formed when an animal dies and gets buried in mud or silt. Over time, sedimentary rock forms on top of the animal’s bones, creating a fossil. This is evidence of change to the landscape because we can age the fossil-based on the different layers of sediment in which it is encased, which also gives us insight into the changes that have occurred in that area of the world over time.
