The document summarizes key information about plate tectonics and associated geological phenomena:
1) The Earth's surface is composed of shifting tectonic plates that move a few centimeters per year, interacting along plate boundaries where they diverge, converge, or slide past each other.
2) Plate interactions cause volcanic eruptions at divergent boundaries and earthquakes at transform boundaries, while convergent boundaries result in earthquakes, volcanoes, and mountain-building.
3) Most earthquakes and volcanic eruptions occur along plate boundaries, with different eruption types depending on the volcano shape and composition of ejected material.
This is the summary on gateway 1 on plate tectonic. It discusses about the following:
1) Characteristics of the different structure of the earth.
2) The mechanism leading to plate movement
3) Landforms associated to the different plate movement.

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

1. SPHERES OF THE EARTH
• The Earth has 4
spheres:
2. ATMOSPHERE
3. HYDROSPHERE
4. LITHOSPHERE
5. BIOSPHERE
2. EARTH’S INTERIOR
• The outer shell of the
Earth is called the
CRUST
• The next layer is
called the MANTLE
• The next layer is the
liquid OUTER CORE
• The middle bit is
called the solid
INNER CORE
5. PLATES
• The Earth's surface is made up of a series of
large plates (like pieces of a giant jigsaw
puzzle).
• These plates are in constant motion travelling
at a few centimetres per year.
• Plates 'float' on the molten rock magma. As
the core of the Earth heats up the materials
inside, the molten magma also gets heated up.
The heat causes convection currents, a
movement of rising and sinking caused by
heat, inside the molten magma.
6. PLATE MARGINS
• The place where two plates meet is known as plate
margin/ boundary.
• There are 3 types of plate margins/ movements:
3. Diverging Plate Margin
4. Converging Plate Margin
7. DIVERGING PLATE MOVEMENTS
• Places where plates are coming
apart are called divergent
boundaries.
• when Earth's brittle surface
layer (the lithosphere) is pulled
apart, it typically breaks along
parallel faults that tilt slightly
outward from each other.
• Magma (liquid rock) seeps upward
to fill the cracks. In this way,
new crust is formed along the
boundary.
• Earthquakes occur along the
faults, and volcanoes form where
the magma reaches the surface.
• For example, divergence along
the Mid Atlantic ridge causes
the Atlantic Ocean to widen at
8. CONVERGING PLATE MOVEMENTS
• When two plates move towards
each other, they would collide.
This is called a convergent plate
movement.
• As the plates collide, some crust
is destroyed due to the impact,
therefore this convergent
boundary is also called a
destructive boundary.
• Examples:
4. the collision between the
Eurasian Plate and the
Indian Plate which is forming the
Himalayas.
5. subduction of the Nazca Plate
beneath the
South American Plate to form
12. CONSERVATIVE PLATE
MOVEMENT
• A transform plate
movement is one where
two plates slide laterally
past each other.
• This movement is not
smooth due to friction
between the rocks of
the two plates.
• When there is
sufficient buildup of
pressure, rocks in the
plates break and get
jerked apart. This
results in earthquakes.
13. HAZARDS ASSOCIATED WITH
PLATES
• Most
EARTHQUAKES
and VOLCANIC
ERUPTIONS
occur in specific
areas, such as
along plate
boundaries.
16. EFFECTS OF EARTHQUAKES
• Negative effects of
earthquakes:
• Tremendous loss of life.
• Loss of property.
• Collapse of transport –
roads, railways, ports,
bridges.
• Fire, landslides, floods.
• Blocked roads
• Facilities disrupted –
electricity, water,
medical.
17. VOLCANO
• A Volcano is an opening or
rupture on the Earth’s Surface
which allows magma, rocks,
gases etc. to come out from
below the surface.
• Causes of Volcanic activity:
d) Diverging plates
e) Converging plates
f) Hot Spots
g) Faults
• Important Terms:
• Vent and Fumeroles
• Crater
• Pyroclastic material
• Lava flow
• Magma Chamber
• Cone shaped hill
18. TYPES OF MATERIAL - VOLCANO
Three types of materials are ejected out of a Volcano:
•SOLIDS: ash particles (< 2mm in size); Lapilli (2 – 64mm in
size); Volcanic bombs (>64 mm in size)
•LIQUIDS: Molten material – Magma, Hot water from
geysers and hot springs.
•GASES: Water-vapour, carbon monoxide, carbon dioxide,
sulphur dioxide, hydrogen chloride, hydrogen fluoride,
19. TYPES OF VOLCANOES
• On the basis of •
frequency:
• Active Volcano: which
erupt frequently & can
erupt any time. Eg. Mt.
Mauna Loa, Hawaii.
• Dormant Volcano:
which have erupted in
history but have not
erupted since then. Eg.
Mt. Rainier, USA
• Extinct Volcano: which
may have erupted
earlier but is now
almost dead (>1000
On the basis of shape and
material they are made of:
• Shield Volcano: Gentle slopes,
basaltic lava, low viscosity.
Eg. Mt. Mauna Loa, Hawaii
• Cinder Volcano: Steep slopes,
> 300 meters in height, made
of pyroclastic material. Eg.
Mt. Paracutin, Mexico
• Composite / Strato Volcano:
Steep upper slopes & then
gentle, Alternate layers of
20. TYPES OF ERUPTIONS
• There are five major
types of eruptions:
c) Hawaiian
d) Strombolian
e) Vulcanian
f) Pelean
g) Plinian
23. EFFECTS OF VOLCANO
• Positive Effects:
b) Ash add to the soil
fertility – farming
c) New minerals may be
discovered
d) Promotes Tourism
e) Research and
education purposes.
f) Geothermal Energy –
renewable energy.
• Negative effects
b) Loss of life
c) Loss of property (economic
loss)
d) Air Pollution (ash, smoke,
gases, acid rain etc)
e) Water pollution
f) Lahars (mudflows with
water)
g) Earthquakes
h) Increase in temperature
of the area
