Patterns on Earth

LO:SWBAT model and describe slow changes to Earth’s
surface caused by weathering, erosion, and deposition by
water.

(3-Week Assessment)

SCI.4.10B Model and describe slow changes to Earth’s surface caused by weathering, erosion, and deposition from water, wind, and ice.

Essential Understandings &

Guiding Questions

Coastal Landforms

8

Coastline Model

How can you use the materials to create a model that

shows how the ocean interacts with land?

9

Coastline Model: What observations could you record to
better understand the effect of waves on coastal landforms?

Before Making

Waves

After Making

Waves

10

What conditions do you think cause
clouds to form in a natural system?

Coastline Investigation

Waves

Erosion

The process by which forces move weathered rock from one place to another

11

What conditions do you think cause
clouds to form in a natural system?

Coastline Investigation

What are some limitations of the coastline models?

Coastline Investigation

13

How can weathering and erosion result in a variety of
coastal landform shapes?

14

Other than changes to the shape of the landforms, what
did you notice?

Sediment: the

weathered rock that
is carried away by
wind, water, ice, or

gravity

15

What do you think will happen to the sediment that is
floating or drifting in the water?

Deposition: the

process of weathered
rock building up over

time

16

Where do you see deposition happening in your coastal models?

Delta

Water in a river slows down and sediment in the water is deposited.

18

How are these three processes alike? How are they different?

Landform

A natural feature of the
Earth’s surface

Weathering

The breaking up of
rocks into smaller
pieces by water, wind,
or ice

Erosion

The movement of rocks
and sediments by
water, wind, ice, or
gravity

Deposition

Sediments are
deposited or dropped
off in a new location

Sediment

Material that is broken
down by the processes
of weathering and
erosion and is carried
by wind

Delta

A landform that is
created when sediment
is deposited at the point
where a river meets the
ocean

Canyon

A landform that is a
deep, narrow valley
created by erosion from
ice or water

V-Shaped Valley

A landform that formed
by erosion from a river
or stream over time.

1The freezing of water causes rocks to

break down. This process is

.

2Flowing water breaks away and removes

rock particles from the edge of a river.
This is an example of .

3At points where a river slows down,

some particles are laid down on the
river floor through .

The Rio Grande Valley is located at the southern tip of Texas at the end of a long river
known as the Rio Grande.

How did the delta at the end of the Rio Grande
form?

A.

Sand and mud from the Gulf of Mexico
were washed ashore by tsunamis.

B.

The river cut through the solid bedrock of
the valley.

C.

The river deposited large amounts of
sediment from land erosion.

D.

Hurricanes pushed soil and debris from
the Gulf of Mexico onto the land.
