This is a topographical map of the United States that shows the earthquake fault lines. The red, orange, and purple lines represent areas at risk for earthquakes. Based on this map, what patterns can you describe regarding the United States' earthquake fault lines?

Screen shot 2020 09 01 at 11.59.24 am

Possible Answers:

The southern US is devoid of earthquake fault lines.

The US is devoid of earthquake fault lines.

All of the answer choices are correct.

The western US is devoid of earthquake fault lines.

None of the answer choices are correct.

Correct answer:

None of the answer choices are correct.

Explanation:

This topographical map allows the readers to see patterns in the Earth's landforms. The earthquake faults are red, orange, and purple, and they can be seen focused on the Western side of the United States.  There are some earthquake faults off the coast of Mexico, Louisiana, Alabama, and Mississippi in the southern US as well. Using maps like these are beneficial for identifying patterns and finding details to describe them. The United States as a whole, including the southern US and the western US, is NOT devoid of earthquake fault lines, so none of the answer choices are correct.

Example Question #8 : Describe Patterns Of Earth's Features

This is a topographical map of the United States. There are many landforms visible on the map and are either color-coded or textured. River, lakes, and oceans can be seen in blue. Green represents forests and wooded areas. Where the map looks rippled or almost three-dimensional are mountain ranges and elevation.

If someone wanted to move to a forested area of the United States, what area would be best?

Screen shot 2020 09 01 at 11.55.06 am

Possible Answers:

All of the answer choices are correct.

The Northeastern US

The Southeastern US

The Western US

None of the answer choices are correct.

Correct answer:

All of the answer choices are correct.

Explanation:

This map is an excellent choice for viewing all of the different features and landforms that the United States has to offer. Some parts of the country are mountainous, others have large bodies of water, and an ocean surrounds some. If someone is looking to move to a place with forested and wooded areas they could move to the western US, southeastern US, or the northeastern US. All of these areas are featured in green which indicated forests and woods.

Example Question #9 : Describe Patterns Of Earth's Features

True or False: Some kinds of landforms, such as mountains and valleys, don't change.

Possible Answers:

True

False

Correct answer:

False

Explanation:

The statement in the question is false. Landforms are always changing, and patterns can be seen in their structures over time. Mountains are massive, so they don’t seem to change, but they are changing all the time. Slowly, over many years, tall, pointed mountains can be worn down until they are lower and more rounded.

Example Question #10 : Describe Patterns Of Earth's Features

NASA has captured information and created a global map of forest height from around the world. (The image is pictured below.) What pattern can be identified from the map?

Screen shot 2020 09 01 at 1.46.22 pm

Possible Answers:

Australia has a large concentration of very tall trees.

North America has a large concentration of very tall trees.

South America has a large concentration of very tall trees.

Antarctica has a large concentration of very tall trees.

Correct answer:

South America has a large concentration of very tall trees.

Explanation:

This map is an excellent choice for viewing all of the different continents and their concentration of tall trees in one visual. Some continents have areas with broad groupings of high canopies while others are bare and colored in white to represent no trees. A pattern that can be identified from this map is that South America has an enormous concentration of tall trees. Northern Africa has no colored parts signifying no tall trees, Australia has some tall canopies on the East coast. Still, it is overall bare, and North America has many mixed height forests.

Example Question #1 : Support An Explanation For Changes In Landscapes

Tara says there are changes in the landscape over time. She believes that throughout millions of years, rock layers and rock formations change, and this shapes our landforms. Her teacher tells her to find a photograph that supports her claim.

Which photo would be best for her to submit to her teacher as evidence?

Possible Answers:

Stone, Wall, Rock, Masonry, Structure

Saxon Switzerland, Rock, Pinnacle

Fog, Coniferous Forest, Spruce, Forest

Stones, Rocks, Pebbles, Tranquil, Zen

Correct answer:

Saxon Switzerland, Rock, Pinnacle

Explanation:

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.

Example Question #2 : Support An Explanation For Changes In Landscapes

What does the term landscape mean? Example: There are changes in the landscape throughout the years due to weathering and erosion.

Possible Answers:

To make an area more attractive with rock formations

Invisible features of an area

To make an area more attractive with plants

Visible features of an area

Correct answer:

Visible features of an area

Explanation:

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.

Example Question #1 : Patterns And Fossils

What factors affect how landscapes change?

Possible Answers:

All of these are factors in changing a landscape

Human activity

Temperature

Moisture

Correct answer:

All of these are factors in changing a landscape

Explanation:

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.

Example Question #4 : Support An Explanation For Changes In Landscapes

How are landscape changes recorded by layers of rocks and fossils?

Possible Answers:

Layers of rock and fossils cannot tell us about changes in the landscape.

The type of fossils and age of the rock can tell how the landscape has changed over time.

Landscape changes are recorded in writing in the fossils and rock layers over time.

Fossils trap information about the landscape within for scientists to analyze.

Correct answer:

The type of fossils and age of the rock can tell how the landscape has changed over time.

Explanation:

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.

Example Question #5 : Support An Explanation For Changes In Landscapes

Fossils and rock layers can explain the changes in landscapes over time.

Possible Answers:

True

False

Correct answer:

True

Explanation:

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.

Example Question #6 : Support An Explanation For Changes In Landscapes

Humans do not contribute to the changing of landscapes.

Possible Answers:

True

False

Correct answer:

False

Explanation:

Human activity such as cutting down forests and acid rain caused by pollution can cause changes to Earth’s landscapes. General construction is another example of a way in which humans can create semi-permanent changes in the landscape.
