Can geologists observe earths interior directly?
Geologists cannot directly observe Earth's interior. Instead, they use indirect methods such as seismic waves, gravity studies, and geothermal measurements to infer the characteristics and composition of the Earth's interior. These methods provide valuable insights into the properties of the Earth's layers without the need to physically access them.
How is the study of the earth's interior an example of indirect observation?
The study of the Earth's interior is an example of indirect observation because we cannot directly access or observe it. Instead, scientists rely on seismic waves from earthquakes, magnetic fields, and other indirect methods to infer the composition and structure of the Earth's interior.
Why is it difficult to determine earths inner structure?
It is difficult to determine Earth's inner structure because we cannot directly observe what lies beneath the surface. Most of our information comes from indirect methods like studying seismic waves, which can provide insights into the layers of the Earth. Additionally, extreme heat, pressure, and the lack of access to deep layers make it challenging to explore and study Earth's interior.
Why is it difficult determine earth's inner structure?
Despite attempts, getting through the crust has proven impossible with current economic and technological constraints. Temperatures vary from 900 to 1600 degrees F at the Mohorovicic discontinuity, the boundary between the crust and the upper mantle. And the lithostatic pressure at the line dividing the crust and the mantle is estimated to be up to 116,000 pounds per square inch. It is not surprising that drill bits and shafts would be under tremendously high stresses. Geologists look into the interior by indirect means; examination of deep sourced volcanic material, meteorite and moon material, and behaviors of seismic waves. Much can also be inferred by computer modeling of Earth's gravitational influence and magnetic field.
Why are submersibles more useful than sonar and satellites for studying undersea life?
Submersibles allow researchers to directly observe, sample, and interact with undersea life in its natural environment, providing detailed data that cannot be obtained remotely. Sonar and satellites, on the other hand, are limited to providing indirect and less detailed information about undersea life, as they rely on bouncing signals off objects and may not capture small or hidden organisms.

What 2 things can't the Hubble observe?
Hubble cannot observe objects smaller than a basketball on the moon or detect dark matter directly.
Why do astronomers have difficulty studying the black hole?
Black holes do not emit light, so we cannot observe them directly
Why can we not be certain about how the earth's magnetic field works?
The Earth's magnetic field is generated by complex interactions in the outer core, which we cannot directly observe or replicate in a lab. Additionally, the field is influenced by dynamic processes in the planet's interior, making it challenging to predict with absolute certainty.
What is one way ultrasound used in medicine?
people use ultrasound technologies, such as sonar and ultrasound imaging to observe things that they cannot see directly.
Can MDF observe water?
no, MDF cannot observe water
What is the total interior angle of a point?
A point has no interior and so cannot have interior angles.
What did I observe about comparing plant and animal cells?
WikiAnswers cannot read your mind to know what you did or did not observe.
What has large interior angle a triangle or heptagon?
A heptagon. It can have a reflex interior angle, a triangle cannot.
Did the brachiosaurus nurture its young?
This question cannot be answered because we cannot observe an extinct creature.
Is the dependent is something that you could change?
No, a dependent variable is the outcome or response in an experiment that is being studied but cannot be directly manipulated or changed. It is typically affected by the independent variable, which is the one that is manipulated to observe its effect on the dependent variable.
