6.E.2 Understand the structure of the earth and how interactions of constructive and destructive
forces have resulted in changes in the surface of the Earth over time and the effects of the
lithosphere on humans.
Clarifying Objectives
Number
Standard
6.E.2.1
SUMMERIZE the structure of the earth, including the layers, the mantle and core
based on the relative position, composition and density.
6.E.2.2
EXPLAIN how crustal plates and ocean basins are formed, move and interact using
earthquakes, heat flow and volcanoes to reflect forces within the earth.
6.E.2.3
EXPLAIN how the formation of soil is related to the parent rock type and the
environment in which it develops.
CONCLUDE that the good health of humans requires: monitoring the lithosphere,
maintaining soil quality and stewardship.

Big Ideas
The Earth is made of layers each with its
own unique property.
6.E.2.1
The crust of the Earth is made of large
pieces of rock called plates.
The crust consist of many continental and
oceanic plates that have slowly moved
and changed positions on the globe
throughout geologic time
6.E.2.2
Essential Questions
What does the inside of the Earth like?
How do we know the composition of
Earth’s layers?
How do Earth’s layers compare with one
another?
Forces within the Earth cause
earthquakes and volcanoes.
How do convection currents cause the
Earth’s plates to move?
Convection currents within the Earth’s
mantle cause the movement of the
Earth’s plates.
What is the drive force of plate
tectonics?
Continental plates are thicker and less
dense than oceanic plates
Where do most earthquake and
volcanoes occur?
Most all earthquakes and volcanic activity
occur along crustal plate boundaries
The formation of soil is related to the
parent rock type and the environment in
which it develops.
6.E.2.3
The formation of soil is related to the
disintegration and weathering of rocks
such as limestone, granite, quartz, and
shale.
Composition, texture, soil fertility, and
resistance to erosion are greatly

What is soil made of?
How is soil formed from parent rock
type?
Why is soil in one location different from
soil in another location?
How do environmental factors influence

influenced by plant roots.
the formation of soil?
Different soils have many properties such
as texture, particle size, pH, and the
ability to hold moisture
How do scientists describe soil
scientifically?
Soil is composed of Minerals, Water, Air,
and Organic Matter
How can particle size influence
formation of soil?
Particle sizes (Sand, Silt, Clay) of soil can
range from: Sand: 0.05mm – 2mm , Silt:
0.002mm – 0.05mm, Clay: <0.002mm
Air spaces (pores) in soil allow water to
drain through the soil. Larger particle size
faster drainage. Smaller particle size
slower drainage
6.E.2.4
Monitoring the lithosphere, maintaining
soil quality, and stewardship are essential
to human health.
Why is it necessary to monitor the
lithosphere, maintain soil quality, and be
good stewards?
To improve soil quality and help maintain
stewardship, famers use vegetative
cover, crop rotation, contour plowing and
conservation plowing.
How do humans limit the impact on soil
quality?
Technology, such as remote sensing can
tell us how humans are constantly
changing the surface of the Earth.
How does remote sensing help monitor
the Earth can’s changing surface.
Learning Targets
Create a model of the interior of the Earth.
