Although nitrogen gas makes up 78% of the atmosphere, we can't use it because _____.

Answers

Answer 1
Answer:

The answer is - it can not be taken out of the atmosphere.

The nitrogen, even though makes for about 78% of our atmosphere, and is by far the most abundant gas in it, we can not use it because it can not be taken out of the atmosphere as it is. If we take nitrogen in the form as it is in the atmosphere it is useless for both, humans and plants. It has to go through a process of ''fixation'' first before we can actually use it in our food.
Answer 2
Answer: Although nitrogen gas makes up 78% of the atmosphere, we can't use it because nitrogen atoms must be broken apart first before. This nitrogen is very much packed and bonded with its atoms and would be useless to use since it can't be used for plants.

The acquisition of data about Earth's surface from a satellite, spacecraft, or specially equipped high-altitude balloon is:________A) GIS.B) GPS.C) remote sensing.D) aerial photography.E) USGS.

Answers

Answer: Remote Sensing

Explanation:

The acquisition of data about Earth's surface from a satellite, spacecraft, or specially equipped high-altitude balloon is remote sensing

Final answer:

The process of obtaining data about Earth's surface from satellites, spacecrafts, or high-altitude balloons is called remote sensing. Instruments on these devices capture data, contributing to our understanding of Earth's geography and climate.

Explanation:

The acquisition of data about Earth's surface from a satellite, spacecraft, or specially equipped high-altitude balloon corresponds to C) remote sensing. Remote sensing is a technology that allows scientists to gather information about the Earth's surface without physically touching it. Instruments on satellites, spacecrafts, or high-altitude balloons can capture images or other data, which can be analyzed to understand various aspects of the Earth's geography, climatology, and more.

Sediment is deposited as a river enters a lake because the(1) velocity of the river decreases
(2) force of gravity decreases
(3) volume of water increases
(4) slope of the river increases

Answers

The correct answer is - (1) velocity of the river decreases.

When the velocity (the speed) of the river decreases, be it at the entry of a lake, sea, ocean, or meandering, passing through a valley with very little change in altitude, the sediment starts to get deposited. This is due to the decrease in force caused by the decrease in velocity, there is not enough force to push the sediments further so they start to deposit because the river is not able to drag them further on.
I believe that the answer is number 1. Sediment is deposited as a river enters a lake because the velocity (speed) of the river decreases - the same reason that sediment gets deposited on a river's meander.

Hope this helps! :)
