OBJECTIVES: By the end of class, students will be able to…
SWBAT explain how transform boundaries shape Earth’s surface.
SWBAT explain how hot spots shape Earth’s surface.
DO NOW
Read and ANNOTATE the information before you answer the quest ions.
The Himalayas are a range of mountains that is 2,400 km long and that arcs across Pakistan,
India, Tibet, Nepal, Sikkim, and Bhutan. The Himalayas are the highest mountains on Earth. Nine
mountains, including Mount Everest, the highest mountain on Earth, are more than 8,000 m tall.
The formation of the Himalaya Mountains began about 80 million years ago. A tectonic plate
carrying the Indian subcontinent collided with the Eurasian plate. The Indian plate was driven
beneath the Eurasian plate. This collision caused the uplift of the Eurasian plate and the
formation of the Himalayas. This process is continuing today.
According to the passage, which geologic process formed the Himalaya Mountains? Use ICE
to support your conclusion.

EARTHQUAKES 101
EARTHQUAKE:
Most earthquakes take place

HOW EARTHQUAKES OCCURS
As tectonic plates push, pull, or slide past each other,
o The stress causes the rock to (change in the shape in response to stress.)
Rock along a fault deforms in mainly two ways:
1. Plastic Deformation: o Rock is
2. Elastic Deformation: o Rock is
o The sudden return of a rock to its original shape is
o During elast ic rebound, energy is released. Some of the energy travels in
seismic waves, causing an earthquake.

GUIDED PRACTICE
TEST TAKING SKILLZ
Directions: Read and ANNOTATE each quest ion before you solve the problem.
The cross section below shows the direction of movement of an oceanic plate over a
mantle hot spot, result ing in the formation of a chain of volcanoes labeled A, B, C, and
D. The geologic age of volcano C is shown.
1. What are the most likely geologic ages of volcanoes B and D?
A. B is 5 million years old and D is 12 million years old.
B. B is 2 million years old and D is 6 million years old.
C. B is 9 million years old and D is 9 million years old.
D. B is 10 million years old and D is 4 million years old.

Diagram I is a map showing
the location and bedrock
age of some of the Hawaiian
Islands. Diagram II is a cross
section of an area of the
Earth illustrating a stat ionary
magma source and the
process that could have
formed the islands.
2. Determine which of the Hawaiian Islands has the great est probability of having a
volcanic eruption. Use ICE to support your reasoning
3. Which graph best represents the ages of the Hawaiian Islands comparing them from point A to point B?
Supporting evidence
4. I f each island formed as the crustal plate moved over the magma source in the mantle as shown in diagram II, where would the next volcanic island most likely
form?
A. southeast of Hawaii
B. northwest of Kauai
C. northeast of Hawaii
D. between Hawaii and Maui

INDEPENDENT PRACTICE Directions: For each key term, explain the “big idea” to a kindergartener.
Then, draw a picture to illustrate the word.

MIX IT UP
The map below shows the Earth’s major tectonic plates and some notable land features.
1. Identify which tectonic plate(s) created the Canary Islands. Describe how this
feature was most likely formed.
13
2. Identify which tectonic plate(s) created the San Andrea Fault . Describe how this
feature was most likely formed.
3. Identify which tectonic plate(s) created the Aleut ian Trench. Describe how this
feature was most likely formed.
4. Identify which tectonic plate(s) created the East Pacific Ridge. Describe how this
feature was most likely formed.

BEAST MODE!
Create a study guide for the three types of plate boundaries and their common
effects.
Key words: seafloor spreading, ridge, rift , subduction, t rench, mountain, volcano **The best ones may be used in future review packets!**
Directions: Read the art icle on earthquakes, use the information to answer quest ions
that follow.

Directions: Support your selection by finding evidence to support your answer OR evidence to
support why another is incorrect. Start your explanation with “The evidence shows that…”
Question Supporting evidence
1. A transform boundary is where
A. two plates pull away from each other.
B. two plates move toward each other.
C. two plates slide past one another.
D. two plates collide.
2. The Hawaiian Islands are riding on the Pacific Plate as it moves
northwestward. They are being formed as the plate moves over a
hot spot in the mantle.
Where is the next volcano
likely to form?
A. Location A
B. Location B
C. Location C
D. Location D
3. In some areas, magma chambers exist close to Earth’s surface.

overlying these magma chambers.

pressure rises back toward the surface through fractured rock?
A. plate subduction
B. geyser formation
C. volcanic eruption
D. earthquake activity
