Grade 8 - Earth Science
TEKS
Effects of Plate Tectonics
(8.9) Science concepts. The student knows that natural events can impact Earth systems.
The student is expected to:
(A) describe the historical development of evidence that supports plate tectonic theory;
(B) relate plate tectonics to the formation of crustal features.

In this Instruction Module, students understand how Wegener's Continental Drift Theory,
evidences of sea floor spreading, and the location of most earthquakes and volcanoes
led to the theory of plate tectonics. They learn about the crustal features associated
with divergent, convergent, and transform boundaries including volcanoes, folded
mountains, fault block mountains, rift valleys, and mid-ocean ridges.

In this interactivity, students identify divergent, convergent, and transform boundaries
based on their description and then identify the crustal features associated with each
of them.

In this simulation, the students recognize that thickness of the lava affects its flow rate
and the type of volcanic structure that is formed. They compare liquids of different
thicknesses. They observe and record the time taken by each liquid to flow down a funnel.
They conclude that thinner the liquid is, the faster it flows. They infer that thick lava leads
to the formation of strato-volcanoes and thin lava forms shield volcanoes.

This glossary is a list of the scientific terms used in the Effects of Plate Tectonics
Instruction Module, along with their definitions. The combined use of text, audio,
and visual descriptions help students understand and retain the words and their meanings.

In this quiz, students answer multiple choice questions to assess their understanding of
the concepts presented in the Effects of Plate Tectonics Instruction Module.

Students demonstrate their understanding of the science concepts acquired from the
Effects of Plate Tectonics Instruction Module by applying it to answer a question.

This activity is used as a note-taking and listening guide by students while viewing the
Effects of Plate Tectonics instructional module. It is designed to focus student's attention
on essential information and key terminology presented during instruction.
