No,they can also occur in the form a tsunami.

Explanation:
Transit Photometry is the most widely-used and effective to date, it has been a method that measures the light curve of distant stars for periodic dips in brightness. These are the result of exoplanets passing or transiting in front of the star relative to the observer. It is currently the most effective and sensitive method for detecting extrasolar planets, particularly from an observatory in space. When combined with radial velocity data, a transit can also provide a good estimate of the planet's mass. This method detects distant planets by measuring the minute dimming of a star as an orbiting planet passes between it and the Earth.
The main reason direct detection of exoplanets is difficult is because most planets orbit planets orbit at small angular separations on the sky, this means a direct detection is only possible if the star's light can be suppressed or occulted such that the faint light from the planet can be detected.
Some planets are found via the wobble method, using both methods, combining mass and size, scientists can calculate the planet's density, an important step towards assessing its composition.
Answer:
True!
Explanation:
A political boundary is an imaginary line separating one political unit, such as a country or state, from another. Sometimes these align with a natural geographic feature like a river to form a border or barrier between nations. Occasionally, two countries may contest where a particular border is drawn.
Environmental Geography mainly focuses on interaction between human and nature.
Explanation:
Environmental Geography is a tool that measures the impact of human lifestyle on nature. It mainly focuses on the interaction between nature and human . Geography can be divided into three part , they are physical, human and lastly the environmental geography.
Various features such as land forms, climate, vegetation, local water cycle cannot determine whether human beings can survive in certain area , it is the life style of the people that determine that whether they will be able to adapt with food and climate.
