lithosphere Flashcards
is the outermost layer
of the Earth, encompassing the crust
and the upper part of the mantle. It is
rigid and brittle, and it is divided into
several tectonic plates.
LITHOSPHERE
was the supercontinent that existed
around 335 million years ago. The concept of
Pangaea is linked to continental drift, proposed
by Alfred Wegener.
Pangaea
large-scale horizontal movements of continents
relative to one another and to the ocean basins
during one or more episodes of geologic time.
Pangaea and Continental Drift
a semi-fluid layer in the Earth’s mantle
located below the lithosphere. It is partially
molten and allows for the movement of
tectonic plates.
Asthenosphere
scientific theory that explains the
movement of the Earth’s lithospheric
plates. It proposes that the Earth’s
lithosphere is divided into several large
plates that move, interact, and cause
geological phenomena (earthquakes)
- Plate Tectonics

GEOLOGICAL PROCESSES
it is when The lithosphere
provides the physical
foundation for
terrestrial ecosystems.
Landforms, such as
mountains, valleys,
and plains, create
diverse habitats for
various species.
HABITAT FOR LIFE
it is when Soil, part of the
lithosphere, is essential for
plant growth. It acts as a
medium for plants to
anchor their roots and a
source of essential
minerals and nutrients.
NUTRIENT CYCLING
it is when Earth’s dynamic
processes, such as plate
tectonics, contribute to the
formation of new
landforms and influence
climate patterns. These
processes impact the
distribution and
adaptation of living
organisms.

Soil Erosion
Land Subsidence
Earthquakes Induced by Human Activities
it is the Clearing large areas of forests for
agriculture, logging, or other
purposes disrupts ecosystems
and reduces biodiversity. Many
species lose their natural habitats,
impacting their ability to survive
and reproduce.
