Seismic Structure of Earth's Layers and Key Boundaries

Seismic Portrait of Earth's Layers

Earth's layers are detectable as changes in seismic wave velocity with depth.

The boundary between the upper and lower mantle is visible at 660 km as a sudden change from rapidly increasing P- and S-wave velocities to slow or no change in P-wave and S-wave velocities.

The core-mantle boundary is apparent as a sudden drop in P-wave velocities, where seismic waves move from solid mantle to liquid outer core.

The boundary between the outer core and inner core is marked by a sudden increase in P-wave velocity after 5000 km, where seismic waves move from a liquid back into a solid again.

Crust–Mantle Boundary (Moho discontinuity)

Depth: Its depth is ~10 km under the ocean floor and ~35 km under the continents.

Discovery:

  • Thermal energy is the energy that is exchanged between two bodies or systems of matter that have different temperatures. Thermal energy is also exchanged when a body changes from one physical state to another.

  • Kinetic energy (Ec) is the energy of a body in motion. It depends on the mass and the speed of the body.

  • Potential energy (Ep) is the energy of a body determined by its position. It depends on the body’s mass and position

  • Gravitational Potential Energy
  • Elastic potential energy
  • Electrical energy is energy produced by the movement of charged particles (electrons), due to a potential difference.

  • Radiant energy is energy carried by the electromagnetic waves, such as light, radio waves, microwaves, X-ray or γ rays. It’s called radiation.

Classified in Geography

Written on in English with a size of 5.38 KB

What is economic activity?

Economic activities are all the processes used to obtain the goods and services that people need. The three phases of economic activity are:

  • Production → is all the goods and services which are created as a result of an economic activity.
  • Distribution → is the process of moving goods and services from the place of production to the consumer.
  • Consumption → is all the goods and services that people buy to satisfy their wants and needs.

History of payment

  • Barter → direct exchange of goods
  • Natural coins → valuable natural items, with an agreed value like shells, cocoa, salt, furs
  • Metal coins → the first metal coins were made in Lidia (present-day Turkey) in the 7th century BC
  • Paper money → notes first appeared in

What is Health?

Health is a combination of physical, mental, and social well-being, indicating a state where an individual is not suffering from a disease.

Understanding Antigens

An antigen is a substance that is perceived by lymphocytes and triggers a specific immune response.

Understanding Projection Systems in Technical Drawing

Classified in Visual arts

Written on in English with a size of 2.93 KB

Projecting Points and Shapes

Projecting points onto a plane involves rays passing through the points and intersecting the plane. These intersections are called projections. Projecting a shape involves projecting its vertices.

Projection Systems

There are two main systems of projection:

Perspective Projection

When the rays originate from a single point, the system is called perspective projection. The resulting shape is proportionally smaller or larger.

Parallel Projection

When the rays are parallel, the system is called parallel projection. The resulting shape is congruent (same shape and size). There are two variations:

  1. Oblique Projection: The rays are oblique to the projection plane.

  2. Orthographic Projection: The rays are perpendicular to the projection

The Urbanization Process: From Ancient Cities to Modern Metropolises

Classified in Geography

Written on in English with a size of 3.21 KB

The Urbanization Process

The urbanization process consists of concentrating population and the most dynamic economic and cultural activities within cities.

Antiquity

In Europe, the urbanization process began around the third millennium BC with the creation of cities in the Eastern Mediterranean by trading civilizations like Crete. However, the definitive push toward urbanization came in the 8th century BC, first with the Greeks and then with Roman rule, which spread cities all across the empire.

In Spain, the first cities (Cádiz and Ampurias) emerged in the 8th century BC thanks to colonization by Mediterranean peoples (Phoenicians and Greeks). The number of cities increased during the period of Roman rule, when numerous cities were founded, such... Continue reading "The Urbanization Process: From Ancient Cities to Modern Metropolises" »

Suburbanization: Urban Growth and the Creation of Rural-Urban Areas

Classified in Geography

Written on in English with a size of 2.52 KB

The Suburbs

In the 20th century, particularly between the 1950s and 1980s, urban growth led to the creation of vast suburban outskirts adjacent to historical cities. These areas were subject to characteristic zoning laws that segregated them into residential, industrial, and service-sector zones.

Residential Zones

Residential zones vary based on residents' buying power, resulting in social segregation: slums for disadvantaged or marginalized groups; tower block neighborhoods of varying sizes and qualities for the middle and lower classes; and exclusive single-family housing developments for the upper classes.

Industrial Zones

Industrial zones house factories that have relocated from city centers, as well as new industries seeking lower land prices... Continue reading "Suburbanization: Urban Growth and the Creation of Rural-Urban Areas" »
