Whatever fossil is at the lowest layer is the oldest cuz the old fossils lived along time ago and when they died the fossils were buried.
Answer:
the same brightness and the same type of star
Explanation:
Geothermal energy is the energy drawn from the earth (geo) by way of the hot rocks that are found there. It is created as a result of the tremendous heating caused by the fission of radioactive elements in the earth's core.
Nobody has even gotten close to directly examining the interior of the Earth. So there is disagreement among geophysicists as to how heated the Earth's core is. However, the speed at which earthquake waves, sometimes known as "seismic waves," move can reveal a lot to scientists about the composition of the Earth.
It is thought that the Earth's core temperature ranges between 5,000 to 7,000 degrees Celsius. That is far colder than the sun's inside, yet roughly as heated as the sun's surface.

Air mass, letter a is the correct one
Answer:
water it yield is 244290.45 ft
Explanation:
given data
specific storage SS = 2.4 × 
ft
thickness b = 300 ft
water declined ΔH = 4.8 ft
radius r = 1,500 ft
to find out
How much water would it yield
solution
we know that
volume of water is
Vw = S × Area × ΔH ..............1
here S = specific storage × thickness
S = 2.4 × × 300
S = 7.2 × 
and
area = πr² = π 1,500² = 7068589.471 ft²
so
volume of water is
Vw = 7.2 × × 7068589.471 × 4.8
Vw = 244290.45
so water it yield is 244290.45 ft
