2. Sequence stratigraphy - Wikipedia

   en.wikipedia.org/wiki/Sequence_stratigraphy

   Sequence stratigraphy is a branch of geology, specifically a branch of stratigraphy, that attempts to discern and understand historic geology through time by subdividing and linking sedimentary deposits into unconformity bounded units on a variety of scales. The essence of the method is mapping of strata based on identification of surfaces ...

3. Massive parallel sequencing - Wikipedia

   en.wikipedia.org/wiki/Massive_parallel_sequencing

   Second, the DNA is sequenced by synthesis, such that the DNA sequence is determined by the addition of nucleotides to the complementary strand rather than through chain-termination chemistry. Third, the spatially segregated, amplified DNA templates are sequenced simultaneously in a massively parallel fashion without the requirement for a ...

5. Stream order - Wikipedia

   en.wikipedia.org/wiki/Stream_order

   Stream order is an important aspect of a drainage basin. It is defined as the measure of the position of a stream in the hierarchy of streams. Tributaries are given a number one greater than that of the river or stream into which they discharge. So, for example, all immediate tributaries of the main stem are given the number "2".

6. Earth's energy budget - Wikipedia

   en.wikipedia.org/wiki/Earth's_energy_budget

   Earth's energy budget (or Earth's energy balance) is the balance between the energy that Earth receives from the Sun and the energy the Earth loses back into outer space. Smaller energy sources, such as Earth's internal heat, are taken into consideration, but make a tiny contribution compared to solar energy.

7. Petroleum geology - Wikipedia

   en.wikipedia.org/wiki/Petroleum_geology

   Petroleum geology is principally concerned with the evaluation of seven key elements in sedimentary basins : A structural trap, where a fault has juxtaposed a porous and permeable reservoir against an impermeable seal. Oil (shown in red) accumulates against the seal, to the depth of the base of the seal. Any further oil migrating in from the ...
