D. Olduvai Gorge
Explanation:
- From 1935 to 1959, Louis and Mary worked hard in several excavations in Kenya and Tanzania, looking for the remains of early humans. Although they encountered many difficulties, both because of the dangerous and inaccessible terrain and the scarce postwar scientific foundations.
- However, the real breakthrough came in 1959, when one morning in the Olduvai Gorge - a region separating the famous National Park from Tanzania's more famous Serengeti National Park - Mary discovered a 1.75 million-year-old hominid skull, later classified as Parantropus boisei.
- This finding was a strong argument that hominids evolved in Africa.

These subs are useful in studying the ocean floor, where it is so deep that divers would be crushed by the water pressure. For example, research submersibles are used to study shipwrecks like the RMS Titanic.

Erosional landforms occur more often in the colder periods of the year because in this parts of the year there's usually more rain, and also there's snow ,and most importantly ice. The rain and snow contribute to the chemical decomposition of the rocks, while the ice with it's pressure contributes to the physical decomposition of the rocks, by literary increasing it's volume inside the cracks of the rocks and break them from the inside.
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.
