The amount of gravitational pull helps determine the gases that can form an atmosphere around a large body in space. So the mass of an object also determines the density of these gases. Note that several factors come into effect for a large object to sustain their gases if present.
Answer: c. Point B has an elevation less than 2750 feet.
Explanation:
The lines drawn on the map are known as contour lines and they are used to measure elevation. Point B is on a river and rivers are only able to flow at a lower elevation than the area around them.
Point B is therefore lower than the area around it and as the closest contour line to it puts the area at an elevation of 2,750 feet, that must mean that Point B is lower than 2,750 feet.
1- C ( this is an assumption; a hypothesis is always based on an assumption.
2- F ( this states to share the results with other classmates).
3- D (this is a description of an experiment you could conduct; you test a hypothesis (usually) by conducting an experiment.
4- A (this is something you could observe during the experiment, therefore it is an observation).
5- E (this sentence is a conclusion).
6- B (This is an actual question)
