Astronomers use __________ to remotely identify the ________ of an object by the unique pattern of lines in its spectrum.
Aliun [14]

Answer:Spectroscopy helps astronomers to determine the composition, temperature, density, and motion of an object.

Infrared spectroscopy helps to identify the atoms and molecules in the object.

The red shift or blue shift (Doppler Effect) in a spectral line tells how fast the object is receding from Earth or coming toward it.

The Doppler shift enables astronomers to discover extrasolar planets.

As a planet orbits its star, the star is alternately moving away from or toward us.

Astronomers can use the Doppler shifts to calculate the speed of the star and the mass of the planet that is tugging on it.

Which of the following are contributing factors to the extinction of species?
meriva

Answer:

Deforestation

Climate Change

Invasive Species

Explanation:

Seventy percent of the Earth's plant and animals dwell in forests, and deforestation affects them directly. Once their habitat is lost, they are on their way to extinction.

Climate change also causes extinctions not only as a result of species intolerance to high temperature, but more commonly via a variety of related factors that alter a species’ interactions with other species.

Invasive species invade foreign territory. They use resources that the other species depend on. Then naturally one of the species will die off.
