It comprises all the
the space and time, and all the energy and matter in it.
(a)
Matter consisting of protons, electrons, and neutrons: atoms, planets, stars, galaxies, nebulae, and other bodies
Black Hole
Cold Dark Matter
Dark energy
Baryonic Matter
______ can explain what may be holding galaxies together for the reason that the low total mass is insufficient for gravity alone to do so while dark energy can explain the observed accelerating expansion of the universe.
Black Hole
Cold Dark Matter
Dark energy
Baryonic Matter
Hydrogen, helium and (a) are the three most abundant elements.
Are the building block of galaxies born out of clouds of gas and dust in
galaxies
(a)
TRUE or FALSE: The remaining dust and gas may end up as they are or as planets, asteroids, or
other bodies in the accompanying planetary system.
True
False
It occurs when the source of light is moving away from the observer or when the space between you and the source is stretched.
(a)
It states that at a certain point in time, it will stop expanding and collapse into itself, pulling everything with it until it eventually turns into the biggest black hole ever.

Big Bang Theory
Steady State Theory
Pulsating Universe Theory
It states that the universe has been present ever since and therefore has no beginning and no end.
Big Crunch Theory
Big Bang Theory
Steady State Theory
Pulsating Universe Theory
In this theory, energy and matter divided and became distinct from each other. After the massive explosion, dust and portion of the condensed matter and energy spread out.

He concluded that meteorites contain matter that had changed very little in the early history of the solar system. This set a new trend in understanding the solar system whose origin can be based on its chemical composition.

It is an excellent solvent, capable of dissolving many substances
(a)
It is considered that portion of the Earth system that includes the Earth's interior, rocks and minerals, land forms and the processes that shape the Earth's surface. It makes up the solid portion of the Earths layer, its structure and land.

Scientists believe that deep down inside the Earth, there’s a huge ball of liquid and solid iron.
(a)
It has a thin layer measuring 40 km deep composed of solid rocks and minerals.
Crust
Mantle
Core
It represents about 85 % of the total weight and mass of our planet. It is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust.
(a)
This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapor (gas). Water vapor droplets join together to make clouds.
Evaporation
Condesation
Precipitation
Collection
A layer in the earth's stratosphere at an altitude of about 6.2 miles (10 km) containing a high concentration of ozone, which absorbs most of the ultraviolet radiation reaching the earth from the sun
(a)
Termed as the “zone of life”, it is the part where life exists. So far there has been no existence of life elsewhere in the universe
