Earth and Space Sciences
Explain that many processes occur in patterns
within the Earth’s systems.

Patterns within the Earth's
System
The Benguela Current:It
begins as a northward flow off
the Cape of Good Hope, where
it skirts the western African
coast equatorward until around
24°S-30°S. Here most of it
separates from the coast as it
bends toward the northwest.
However, two branches of the
current do continue along the
coast, and one of them joins
the Angola Current at the
Angola-Benguela front near
16°S
The Caribbean Current:is a
semi-enclosed sea adjacent
to the landmasses of
Central and South America.
The closely spaced chain of
islands, banks, and sills of
the Antilles Islands Arc
separate the Caribbean from
the Atlantic Ocean and act
as a sieve for the inflow of
Atlantic water
Earth and Space Sciences
Explain the process that move and shape
Earth’s surfaces.

The Four Process That Shape The Earth's
Surface.
Solidification:atoms of a
liquid, such as melted metal,
begin to bond together at
the nucleation points and
start to form crystals
Weathering:the breaking
Erosion:the process of
weathering and transport of
solids (sediment, soil, rock
and other particles) in the
natural environment or their
source and deposits them
elsewhere
down of rocks, soils and
Deposition:molecules
minerals as well as
settling out of a
artificial materials through
solution.
contact with the Earth's
atmosphere, biota and
waters


Erosion because the wearing down and the
moving of rocks and soil from one place to
another.
The natural agents of erosion are water,
wind, and ice.
What process is mainly responsible
for shaping the Earth's surface?

The nuclear division plus
cytokinesis, and
produces two identical
daughter cells during
prophase,
prometaphase,
metaphase, anaphase,
and telophase.
What is Mitosis?



A special type of cell
division necessary for
sexual reproduction.
In animals meiosis
produces gametes like
sperm and egg cells.
other organisms like fungi
generates spores.
