Much of the information taught in Earth-Space Science would not be available if it weren’t for our remote sensing abilities. Explain two ways our remote sensing strategies contribute to our knowledge of these topics.

Explanation:

Remote sensing means we do not have to be physically present in that particular area that we're studying by taking certain measurements. Several tools have been developed overtime to enable us to make this feat possible. Satellites in orbit have a major role to play in this regard. They exist to gather information from outer space and captures images that help us know more about our universe.

Hope that answers the question, have a great day!

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

there are no contact forces mentioned on the list of choices that you've provided.
