The two tools used are:
- A relationship existence between a galaxy's distance from Earth and also that of its speed.
- The findings in the 1960s of the presence of cosmic microwave background radiation.
<h3>What evidence is collected by each tool?</h3>
The evidence to support the big bang are:
- There was found to be some red shifts of a lot of galaxies which connote that the universe is widening.
- Due to the widening of universe, new elements were formed such as hydrogen, deuterium and others.
- Microwaves were found by orbiting detectors.
Therefore, The two tools used are:
- A relationship existence between a galaxy's distance from Earth and also that of its speed.
- The findings in the 1960s of the presence of cosmic microwave background radiation.

The first people to reach the summit of mount everest was ir Edmund Hilary and Sherpa Tenzing Norgay on May 29, 1953.
Tropical places are hot because the humidity coming from the moisture of the plants and water are heated by the sun on the top layer of the tropical zone. The climate varies little in rain forest. There are five layers in the tropic trees so it's so thick that barely any light come through. This is also why vines grow up the trees so they can reach the sunlight to get nutrients. Also, the tropics are near the equator and that also causes the heat. The polars are cold because they barely get any sun heat to melt the snow or warm it up. The polars are melting due to certain chemicals and gasses in the atmosphere. also known as global warming. Hope that was helpful!
Answer:
Due to gravity and volatile matter.
Explanation:
- As the rocky matter is refractory as it forms in the relatively high and warm and the presence of the gravity also plays a crucial role in the formation of the rocky masses.
- The volatile matter solidifies at a cold temperature and such as those in the outer parts of the nebula and thus gas giant is cold and icy plants as they form away from the sun and have distinct gravitational compositions.
