CFE Science

The student created a model for his Science Class. Which model best represents the formation of a delta?

• A student carefully placed pieces of gravel in a hill.

• A student set up a tray of sand and blew through a straw to form a hill of sand.

• A student poured water into a stream table filled with dirt and observed sediments get deposited at the end of the table in a triangular shape.

• A student packed damp sand in a tray then scraped a large ice cube along the bottom.

A diagram of a delta is shown. Which process best describes the formation of this delta?

• The erosion of sediments in the ocean

• The weathering of rock by glaciers

• The deposition of sediments carried by the ocean

• The deposition of sediments carried by the river

Which of the following processes is not considered a rapid change to Earth’s surface?

• Volcanic eruption

• Earthquake

• Landslide

• Weathering

The process in which rock is broken down into smaller pieces is

• Erosion

• Weathering

• Deposition

• Compaction

When water enters the cracks in a large rock and freezes, the water expands. Over time, water freezing and thawing –

• erodes the large rock through a river

• weathers the rock into sediments

• deposits lava in a new place

• changes the rock into a glacier

• U-shaped valley

• Canyon

The images show a river delta and sand dunes. Which statement best explains how the formation of deltas and sand dunes is similar?

• Both are formed by the movement of glaciers.

• Both are formed by water eroding sediments.

• Both are formed by wind weathering rocks.

• Both are formed be deposition of sediments.
