What do we mean when we say that the terrestrial worlds underwent differentiation?
When their interiors were molten, denser materials sank toward their centers and lighter materials rose toward their surfaces.
Which of the following best describes what we mean by a terrestrial world’s lithosphere?
a terrestrial world’s lithosphere is.
a layer of relatively strong, rigid rock, encompassing the crust and part of the mantle
.
What is terrestrial world lithosphere?
a layer of relatively strong, rigid rock
, encompassing the crust and part of the mantle. The two most important processes in heating the interiors of the terrestrial worlds are: (1) Heat deposited by the process of formation; (2) heat released by radioactive decay.
In what ways is Earth different from the other terrestrial planets?
While Earth is only the fifth largest planet in the solar system, it is the only world in our solar system with
liquid water
on the surface. Just slightly larger than nearby Venus, Earth is the biggest of the four planets closest to the Sun, all of which are made of rock and metal.
What are the conditions necessary for a terrestrial planet?
What are the conditions necessary for a terrestrial planet to have a strong magnetic field?
Very high pressures
, like those found deep within planetary interiors, can compress rocks so much that they stay solid even when temperatures are high enough to melt them under ordinary conditions.
What is lithosphere very short answer?
The lithosphere is
the solid, outer part of the Earth
. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. … Oceanic lithosphere is associated with oceanic crust, and is slightly denser than continental lithosphere.
What are the two types of crust?
Earth’s crust is divided into two types:
oceanic crust and continental crust
. The transition zone between these two types of crust is sometimes called the Conrad discontinuity. Silicates (mostly compounds made of silicon and oxygen) are the most abundant rocks and minerals in both oceanic and continental crust.
Why is Earth called a terrestrial?
The planets Mercury, Venus, Earth, and Mars, are called terrestrial
because they have a compact, rocky surface like Earth’s terra firma
. … Of the terrestrial planets, Venus, Earth, and Mars have significant atmospheres.
What do you mean by terrestrial life?
Supplement. The term terrestrial in biology is generally used to describe
living organisms that live and grow on land
. Living things that make use of nature as their habitat may be grouped based on where they live, grow and reproduce. Living things that spend most of their life on land are called terrestrial.
What separates the inner and outer planets?
Our solar system contains nine planets.
The asteroid belt
separates the inner and outer planets.
Is Earth the only planet with life?
The third planet from the sun, Earth is the only place in the known universe confirmed to host life. With a radius of 3,959 miles, Earth is the fifth largest planet in our solar system, and it’s the only one known for sure to have liquid water on its surface. …
Earth is the only planet known to maintain life
.
What features of Earth enables life to exist?
What makes the Earth habitable? It
is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field
, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.
What are the similarities and differences among these three terrestrial planets?
Answer. Answer: their similarities are:
they are planets, having individual paths to orbit, and they are revolving around the sun
. Differences: venus is closer to the sun, earth is after the venus and mars is after the earth. But one thing is that the earth is more beautiful than venus and mars.
What is the difference between terrestrial and jovian planets?
Terrestrial Planets: Coming from the Latin word “terra”, meaning “land,” the terrestrial planets are Mercury, Venus, Earth and Mars. … Jovian planets are larger, further from the sun, rotate faster, have more moons, have more rings, are less dense overall and
have denser cores than terrestrial planets
.
What planet is closest to the Sun?
Mercury
. Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth’s Moon. Mercury is the fastest planet, zipping around the Sun every 88 Earth days.
Which two terrestrial planets are of the same size?
Venus
: Venus is often referred to as Earth’s “sister planet“, and not without good reason. At 12,104 km (7521 mi) in diameter, it is almost the same size as Earth. But unlike Earth, Venus experiences no flattening at the poles, which means that it almost perfectly circular.
