Lewis and Clark did map the route to the pacific oceans though they were not able to find a direct water route as they had hoped. The Majority of their trip was along the Missouri River and thus it is the closest thing to a "Northwest Passage" that the explorers were able to find.

d. lightning
Explanation:
It is described as a cloud that is masked and dense, with considerable vertical development, in the form of a mountain or huge towers. Part, at least of its top is normally smooth, fibrous or striated, and almost always crushed; This part often extends in the form of an anvil or a vast plume. Below the base, very dark, low clouds appear torn and rainfall or showers.
They are composed of water droplets and ice crystals on top or anvil. In their interior they also contain large raindrops, snowflakes, granulated ice, hail and in cases of extreme instability of large size.
They almost always produce a storm, that is to say, precipitation in the form of showers, of rain or hail, generally, although also of snow in winter, accompanied by gusty winds and electric discharges that occur between clouds or between cloud and earth (lightning) and even tornadoes
Answer:
Given that this is a question with various questions in them, I will try to provide you with the answers for each, and a short explanation.
1. The: astromeric method was used to find a Jupiter-sized planet through careful measurements of the changing position of a star in the sky. This method is the best for finding particularly large planets orbiting away from their stars and its purpose is to detect movements of those bodies against the backdrop provided by other stars. This technique is best used to detect astral bodies close to Earth, big ones and for stars that are close.
2. Discovering planets through the: Doppler method requires obtaining and studying many spectra of the same star. This method is best used for astral bodies that are close by. It detects movements from stars by using something called the Doppler shifts. It can detect massive planets regardless of their orbits, except when the orientation is face on towards Earth.
3. The Kepler mission successfully discovered thousands of extrasolar planets with a spacecraft that searched for transits among some 100.000 stars. Launched in 2009 by NASA, and named after astronomer Johannes Kepler, this enormous telescope was launched to discover planets that were the size of Earth and which were orbiting other stars. The technique it uses to do this is known as the transit method.
4. The transit method is used to find extrasolar planets by carefully monitoring changes in a star´s brightness with time. This method has been the most used, and most successful up to this point for finding the most extrasolar planets. It is the method used by the Kepler mission to discover these extrasolar planets.
