Scientists say sun's influence penetrates into deep Earth

"For years, scientists believed that changes in the Earth's interior, such as volcanic eruptions and tectonic plate collisions, primarily affected the surface environment."

"(...) a new study published in Nature Communications has revealed a surprising new aspect: solar radiation can also affect the Earth's deep interior."

Solar radiation varies with latitude, creating temperature gradients on the sea surface that affect the distribution of marine life. These carbon-rich organisms are transported into the Earth's interior by the subduction of oceanic plates. Researchers from the Institute of Geology and Geophysics of the Chinese Academy of Sciences have discovered that this process significantly affects the redox state of arc magma.

The "redox" state of arc magma refers to the balance between reducing (losing oxygen or gaining electrons) and oxidizing (gaining oxygen or losing electrons) conditions within magma formed in volcanic arcs. Marine organisms serve as organic carbon and act as a major reducer for the solid Earth. Consequently, the redox state of arc magma can reflect how the sun's influence penetrates deep into the Earth."

Interior of the Earth.

Interior of the Earth.

 Hello friends,As you know  that our Earth have different types of crust and landforms so we don’t know no that what is going on our interior of the Earth and how can we found the details about interior of the Earth. So today I am going to say about something that how can we know about interior of the Earth.(And how scientists use various ways to know about interior of the Earth.Interior of the…

Earth's interior- Layers of the earth | geography4u.com

Based on the physical conditions, Earth can be divided into three layers (crust, mantle and core). Crust is the uppermost layer of earth.

The surface of the earth is an outcome of the processes operating in the interior of the earth. Both exogenic and endogenic forces are constantly shaping the landscape of Earth. It is fascinating to know how scientists have gathered information about the different layers of the Earth.

[ad_1]

When an earthquake strikes, nearby seismometers pick up its vibrations in the form of seismic waves. In addition to revealing the epicenter of a quake, seismic waves can give scientists a way to map the interior structures of the Earth, much like a CT scan images the body.

By measuring the velocity at which seismic waves travel at various depths, scientists can determine the types of…
