Question

Many scientists believe the solar system formed _______________ago, Question 1 options: over 4.5 billion years under 1 billion years over 500 billion years under 2.5 billion years
Much of what we know about our solar system is based on __________________?

Question 2 options:

observations of younger, nearby star systems


planets, planetary objects

computer simulations, and models.

all the aboveHow do Scientists think our sun was created, or born?

Question 3 options:

Other life forms constructed gravitational hydrogen atoms that pulled together to create the sun.


The force of gravity pulled more and more material into the center of this swirling disk. Eventually, the pressure in the center was so great that hydrogen atoms began to combine and form helium, releasing a tremendous amount of energy.


The sun was genetically constructed in a laboratory and released into the atmoshere and allowed to coninue it's nuclear fission until it was large enough to be a sun


Scientists have never investigated the sun

The earth's core and surface are made up of what elements?

Question 4 options:

core is made up of heavy elements, such as iron and nickel, andl ighter elements, such as potassium and sodium make up the surface.


core is made of lava and mud and the surface is made of sand and dirt


core is made up of heavy elements, such as gold and hydroge, and the crust is made of dirt and sediment.


core elements are unknown beause no scientist has ever been there

An explanation for planetary differentiation is_____________.

Question 5 options:

all the planets are different colors and some have life, while others do not


different scientist are chosen to explore planet simularities


The process through which distinct layers with characteristic chemical and/or physical properties are formed


planets have different orbits around the sun and therefore consist of varying elements

this is sience btw

Answer 1

Answer:

Question 1: over 4.5 billion years all the above

Question 2:  all the above

Question 3: The force of gravity pulled more and more material into the center of this swirling disk. Eventually, the pressure in the center was so great that hydrogen atoms began to combine and form helium, releasing a tremendous amount of energy.

Question 4: core is made up of heavy elements, such as iron and nickel, and   lighter elements, such as potassium and sodium make up the surface.

Question 5: The process through which distinct layers with characteristic chemical and/or physical properties are formed
