A delta is:
• Large amounts of sediments are deposited at the mouth of a river.
• Erosion and deposition are the processes that create a delta.

Survey is bringing its broad scientific understanding of the Mississippi
River delta
Rivers and streams can carry sediments
long distances before they are
deposited. When sediments are
deposited at the mouth of a river a
delta is formed.
Sand, silt, clay and rocks are eroded from
areas upstream. The river current sweeps up
those materials and carries them until the
speed of the water slows. When the force of
the water movement becomes very slow, the
heavier materials drop to the riverbed, then
the other materials drop in order of their
weight. This creates layers of sediment that
build up and fan out, creating a delta.

Sediments collect in
layers
• Layers of sediment collect and pile up over
time due to deposition.
• Deposition is the geological process in which
sediments, soil and rocks are added to a
landform or landmass. Wind, ice, water, and
gravity transport previously weathered surface
material, which, at the loss of enough kinetic
energy in the fluid, is deposited, building up
layers of sediment.

The crust is where the action is. The entire
rock cycle takes place in the crust, from
magma pools deep below, to mountain
peaks, high above the surface.
Earthquakes, are often preceded by warning
trembling, called foreshocks.

Seven major tectonic
plates
According to the Theory of Plate
Tectonics, the Earth has seven major
or primary plates: the North American,
South American, African, Antarctic,
Indo-Australian, Eurasian and
Pacific. There are also several
secondary plates including the Arabian,
Caribbean, Indian and Philippine Sea
plates, and tertiary plates which make up
sub-sections of the major plates of the
Earth. (Text courtesy of:

What Happens During an Earthquake?
While tectonic earthquakes can occur at any location around
the world, the majority of large earthquakes—about 80
percent—occur at the circum-Pacific seismic belt found
along the rim of the Pacific Ocean. Two other regions
regularly exhibiting earthquakes include the Alpide belt,
extending along the southern margin of Eurasia through the
Himalayan Mountains, Sumatra, and Java; and the Mid-
Atlantic Ridge running along the floor of the Atlantic Ocean.
When an earthquake occurs, different types of energy waves
are generated.
"P waves" or "primary waves" are the first waves to be
detected. These are compressional waves that push and pull
as they move through rock and fluids.
"S waves" or "secondary waves" are the next waves to be
detected. These waves move only through rock. They move
up and down or side to side, perpendicular to the direction
in which the wave is moving.
Surface waves follow P and S waves. They travel along the
surface of the earth and thus cause the most damage.
Surface waves can be characterized as Love waves, which
are faster and move the ground from side to side, and
Rayleigh waves, which roll like waves on the surface of
oceans and lakes.

• What other types of earthquakes exist?
• In addition to tectonic earthquakes, seismologists
have classified three more earthquake types:
• Volcanic: Earthquakes that occur in conjunction
with volcanic activity
• Collapse: Smaller-scale earthquakes that result
from the subterranean collapse of caverns or mines
• Explosion: Earthquakes caused by underground
explosions of nuclear or chemical devices

• Made of 4 forts and 2000 buildings, in the
17th century Port Royal was a hotbed for pirate
activity. Famed pirates, the likes of Blackbeard
would often make Port Royal their base to raid
treasure ships. That was until 1692, when an
earthquake dragged it under the Caribbean
sea.

Dwarka - India
According to folklore, Dwarka is the home
town of Lord Krishna, a placed believed to be
an old wives tale, a myth, that is until the
ruins were discovered 131 feet below the
ocean. The ruins were found beneath the
surface of modern-day Dwarka. The
complexities and the beauty of this city, has
baffled even experts.

Tsunami is a Japanese word
for “harbor wave”.
• Tsunami can be caused by landslides,
underwater earthquakes, and water
displacement under the ocean.
• A tsunami is a series of waves in a water
body caused by the displacement of a large
volume of water, generally in an ocean or a
large lake. Earthquakes, volcanic eruptions
and other underwater explosions above or
below water all have the potential to
generate a tsunami.

dangerous radioactive waste that is difficult to
store safely.
Geothermal

Water has three stages
Water has a cycle.
Water can be solid ice.
Ice melts and the water becomes liquid.
The liquid water can evaporate when heat is
applied. Liquid water becomes a gas or
vapor.
Then, water vapor can condense into a liquid.
The liquid water can freeze. The frozen
water (ice) can melt, and the cycle continues.

The temperature of a body of
water affects the amount of
dissolved oxygen in the water.
• The higher the temperature,
the lower the dissolved
oxygen. As temperature
increases, the amount of
dissolved oxygen decreases.
• Colder water has more
dissolved oxygen in it.

    What Happens Duringan Earthquake? While tectonic earthquakes can occur at any location around the world, the majority of large earthquakes—about 80 percent—occur at the circum-Pacific seismic belt found along the rim of the Pacific Ocean. Two other regions regularly exhibiting earthquakes include the Alpide belt, extending along the southern margin of Eurasia through the Himalayan Mountains, Sumatra, and Java; and the Mid- Atlantic Ridge running along the floor of the Atlantic Ocean. When an earthquake occurs, different types of energy waves are generated. "P waves" or "primary waves" are the first waves to be detected. These are compressional waves that push and pull as they move through rock and fluids. "S waves" or "secondary waves" are the next waves to be detected. These waves move only through rock. They move up and down or side to side, perpendicular to the direction in which the wave is moving. Surface waves follow P and S waves. They travel along the surface of the earth and thus cause the most damage. Surface waves can be characterized as Love waves, which are faster and move the ground from side to side, and Rayleigh waves, which roll like waves on the surface of oceans and lakes. https://scienceexchange.caltech.edu/topics/earthquakes/w hat-causes-earthquakes Credit: © Agata Nowicka/Marlena Agency for Caltech Science Exchange https://images.app.goo.gl/kY2cupeHhSrndmHS7

    Tsunami is aJapanese word for “harbor wave”. • Tsunami can be caused by landslides, underwater earthquakes, and water displacement under the ocean. • A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions above or below water all have the potential to generate a tsunami. • https://www.surfertoday.com/surfing/what-is-a-tsunami

    Water has threestages Water has a cycle. Water can be solid ice. Ice melts and the water becomes liquid. The liquid water can evaporate when heat is applied. Liquid water becomes a gas or vapor. Then, water vapor can condense into a liquid. The liquid water can freeze. The frozen water (ice) can melt, and the cycle continues. https://3.bp.blogspot.com/-Oa7aWvekaik/TmWSwym16II/AAAAAAAAAtU/-kXuBSVfpdg/s1600/Screen+shot+2011-09- 06+at+3.25.07+PM.png

    The temperature ofa body of water affects the amount of dissolved oxygen in the water. • The higher the temperature, the lower the dissolved oxygen. As temperature increases, the amount of dissolved oxygen decreases. • Colder water has more dissolved oxygen in it. • Image: http://www.mrgscience.com/uploads/2/0/7/9/20796234/544 1371_orig.jpeg
