Natural Processes and Landforms

While on a field trip to Florida, Nora, Hannah, and Ava observed that the rivers and streams were carrying and dropping sediment. They started discussing what types of landforms might be formed by this process. What do you think they concluded?

• oceans and glaciers

• coastlines and deltas

• sand dunes and lakes

• sinkholes and mountains

Lily, Avery, and Evelyn visited a historical park where they saw two statues of the same age. One statue was significantly more worn out than the other. The surface is rough and discolored. What is most likely the cause of the difference in the way the statues appear?

• Deposition from plants growing around the statues

• Erosion from blowing wind in the park

• Physical weathering from animals in the park

• Chemical weathering from acid rain in the city

Why did Alexa, while teaching Arjun, Evelyn, and Nora about erosion, choose to raise one end of the sandbox?

• to demonstrate how erosion of soil in a playground can form miniature rivers

• to demonstrate how wind in a park contributes to erosion

• to demonstrate how erosion in a hilly area builds up mountains

• to demonstrate how gravity on a sloping street contributes to erosion

Noah, Hannah, and Priya are participating in a school debate. The topic is 'Why should we discourage deforestation?'. Which of the following arguments should they use to explain why scientists would recommend not cutting down forests?

• It decreases the erosion of soil.

• It increases the weathering of the land.

• It provides less oxygen to the environment.

• It gives safety to those that live outside the forest.

Charlotte, Olivia, and James went on a field trip to a mountain. They noticed a significant loss of rock formation on the side of the mountain. Which of the following explains how the loss of this rock formation most likely occurred?

• Over time, animals eroded rocks off the side of the mountain

• Over time, rocks were deposited onto the side of the mountain.

• Over time, rocks were deposited by chemical weathering on the top of the mountain.

• Over time, physical weathering slowly broke down the rocks on the side of the mountain.

Sophia, Abigail, and David are planning a trip to Florida. They are discussing the landscape of Florida. Which of the following best explains why they won't find mountains in Florida, but they will find hills?

• Hills are formed near bodies of water while mountains are not, explaining why Florida, being surrounded by water, has so many hills.

• Mountains are higher and steeper than hills, explaining why mountains are not found in Florida's low elevation.

• Mountains are found in places that are dry and cold, explaining why mountains are not found in Florida's warm and humid climate.

• Hills are formed by rocks while mountains are made out of sand, explaining why Florida, being sandy, has so many mountains.

Grace, Aiden, and Zoe are planning a trip to the beach. They are discussing which landform can protect their picnic spot from potential floods and storm surges. Which of the following landforms should they look for?

• rivers

• deltas

• dunes

• caverns

Ava, Benjamin, and Arjun went on a field trip to a river. They noticed a build up of sediment at the end of the river. Which process could have caused this?

• Temperature changes caused the river to deposit sediment.

• The water current changed direction and broke down the sediment.

• The water eroded the soil from the river bank and deposited the sediment.

• Chemical weathering caused the river to break down and erode sediment.

These feature forms when groundwater weathers and erodes the rock underground causing

the surface dirt to gradually or suddenly collapse. What landform is being described?

• Lakes

• Aquifer

• Caverns

• Sinkhole

As Florida's rivers and streams carry and drop sediment, which types of landforms are being

formed?

• oceans and glaciers

• coastlines and deltas

• sand dunes and lakes

• sinkholes and mountains
