Answer:
A, and B.
Explanation:
A and B are the ones that are physical. The others are social and economic.
Answer:
D. form when headward erosion causes one stream to intersect another
Explanation:
Pirate streams -
It is the condition, when the drainage system of a river is directed to flow to to the nearby stream , rather than to its usual flow, is referred to as pirate streams.
This type of condition can originate by several reasons , like -
1. Erosion
2. Tectonic moments
3. natural calamity, etc.
Hence, from the given options , the correct statement regarding pirate streams is D.
<span>We are going to use the fact
that 1cm = 0.00001km to convert 2.1cm/year to 0.000021km/year. Now, since Time =
Distance/Velocity, we replace the values from our problem to get: Time = 519km/ (0.000021km/year) which is equal
to 24714285.71 years. We conclude that Los Angles will be directly west to San Francisco
in a little less than 25 million years.</span>
EQUINOX occurs then; when days and nights are equal
Answer:
Correlation
Explanation:
Correlation simply means matching rocks or strata's of the same age. This rock units or sedimentary strata's may be matched from same region or even different continents.
In correlation the major task is to establish time equivalency of various rocks or sedimentary strata's.
In correlation of rock unit or sedimentary strata, Geologist looks at the physical continuity. For example a sedimentary strata from a region having a particular sequence of rock or sedimentary strata . That same pattern of sequence may be found in another region . With the similarity in the sequence stratigraphy ( sediment layering), Geologist can infer the similarity in age of both strata's.
Fossil contents present in different strata; if similar fossil contents found in different regions, geologist can determine the age similarities.
The first picture indicates strata correlation using fossil similarities while the second picture uses the physical continuity like lithology to correlates strata's
