The sequence of events that can lead to magma becoming soil is C. crystallization followed by exposure and weathering. Under these circumstances it may happen that magma actually turns to soil - it cools off so much that it becomes the ground we walk upon.
The correct answer is - (1) rising expanding cooling condensation.
At first there's the evaporation of water, since the water vapor is less dense than the air it rises up and starts to expend as it goes further upwards in the atmosphere. Once it reaches the upper layers of the troposphere than the cooling process starts because the temperature is decreasing with the altitude. Because of the cooling the process of condensation will start taking place and thus the formation of clouds were the water vapor returns to liquid form and creates rain. The cycle repeats its self all the time.
Answer:
9:00 am
Explanation:
Lines of longitude are imaginary lines running from the north pole to the south pole of earth. These lines are used to calculate the time in places. Also when combined with lines of latitude, they are used to give the exact location of a place.
Given the place is at 45°W longitude and the time at GMT is 12:00 noon.
Degree difference = 0° (GMT) - 45° = -45°
1° = 4 min
time difference = -45° * 4 min per degree = -180 minutes = -3 hours
Therefore the local time at a place 45°W longitude = 12:00 noon - 3 hours = 9:00 am
Answer:
Spirit and Opportunity were sent to Mars to find more clues about the history of water there and see if the Red Planet could ever have supported life.
Explanation:
Both rovers measured the type and abundance of iron-bearing minerals, some of which are associated with water-driven processes. In this way, Opportunity found the mineral jarosite and Spirit found the mineral goethite. The rovers measured chemical elements, some of which are needed for life, in rocks and soils.
With data from the rovers, mission scientists have reconstructed an ancient past when Mars was awash in water. Spirit and Opportunity found evidence for past wet conditions that could have supported microbial life.
Spirit and Opportunity were sent to Mars to find more clues about the history of water there and see if the Red Planet could ever have supported life. To do this, scientists sent the two rovers to two different landing sites. The rovers landed on opposite sides of the planet.
