Which of the following is NOT true about the density pattern of the planets.
a
The outer planets are composed of gas o ice with dense, solid cores.
b
The terrestrial planets have molten, dense cores.
c
Gravity pulled denser materials to the center of each planet in its formation.
d
The outer planets are more dense than the terrestrial planets
Answer:
d
Explanation:
The four inner terrestrial planets are dense compared to the four outer planets. The inner planets are made up mainly of dense, solid rock. The outer planets are composed primarily of gas, so their overall density is lower. However, they are larger in size and much more massive!
Why do we see evidence of impact craters on terrestrial objects, but not on outer planets?
a
Terrestrial objects have solid surfaces while outer planets do not
b
Outer planets have solid surfaces while terrestrial objects do not
c
Terrestrial objects have a stronger gravitational pull
d
Outer planets have a stronger gravitational pull

Earth’s atmosphere contains the element oxygen in two different forms. The chemical formula for oxygen gas is O2. The chemical formula for ozone gas is O3. How does the structure of oxygen gas differ from that of ozone?
I need an explanation and i need it today, thanks!
Answer:
Ozone is a molecule with three oxygen molecules.It is in the upper atmosphere and it protects living organisms by keeping UV rays from reaching the earth's surface. Ozone (O3) is a triatomic, molecule, consisting of three oxygen atoms. ... O3 is the formula for ozone. It has three oxygen atoms.
Explanation:
My brain
In the structure of oxygen molecule, the two oxygen atoms are held by a double bond while in ozone, three oxygen atoms are held by two equivalent bonds of intermediate bond lengths to a central oxygen atom,
In the molecule O2, we have two oxygen atoms connected to each other by a double bond. The bond order in the this molecule is 2 as shown in the image attached to this answer. The bond lengths in this bond correspond exactly to that of an O=O double bond.
In the molecule O3, we can see that there are three oxygen atoms. The central oxygen atom has two other oxygen atoms attached to it. The bond lengths observed in ozone are intermediate between those of a pure double or pure single bond.
The reason behind this is resonance involving the oxygen atoms.

Gold is a natural resource, because it occurs naturally in the environment and humans use it. Gold cannot be made from other substances, and there is a finite supply of it.
What is gold an example of?
A. a fossil fuel
B. a renewable resource
C. a nonrenewable resource
D. a natural pollut
Answer:
Answer below:
Explanation:
A nonrenewable resource
Gold is a metal formed naturally. It is not so abundant in earth and become exhausted when consumed through excavation. Hence, gold is a non-renewable source.
What are renewable resources?Renewable resources are those which never ends as we consumed and can be recycled the used amount as well. Whereas non-renewable resources are no more when we exhausted the existing amount.
Solar energy, wind energy, hydrothermal energy etc are renewable sources. Metals, minerals, nuclear power, coal, fossil fuels etc. are examples of non renewable resources.
Gold is a natural metal used have significant importance and expensive. It cannot made from other substances. Hence, once all the existing gold are taken through mining there will be no more gold. Hence, it is a non-renewable resource.

True or false. All mollusks are cemented permanently to the ground
Answer:
False
Explanation:
Mollusks are living organisms that can move around often, like mussels and clams, and oysters.
The statement "All mollusks are cemented permanently to the ground" is definitely false.
What are mollusks?Mollusks may be defined as a type of living organism that has a soft-bodied invertebrate of the phylum Mollusca, usually wholly or partly enclosed in a calcium carbonate shell secreted by a soft mantle covering the body.
According to the context of this question, mollusks also have the ability to move around their surrounding in order to facilitate their survival and interactions with other living forms. The characteristics of mollusks may include a mantle with a mantle cavity, a shell (except where lost), visceral mass, a foot, and a radula. The odontophore is in the mouth of most mollusks and it supports the radula.
Therefore, the statement "All mollusks are cemented permanently to the ground" is definitely false.
