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.

PLEASE HELP MEEEE
maria [59]

Answer:

Lower the emission of carbondioxide gas and planting more trees.

Explanation:

Lower the emission of carbondioxide gas and planting more trees are the two measures that have been implemented at the national level of countries to ensure the sustainability of coral reefs. Carbondioxide emission is the main reason for the destruction of coral reefs because more carbondioxide emission causes decrease the pH level of ocean. This acidic water of ocean damaged the skeleton of coral reefs and as a result thousands of organisms lost their habitat.

Solve for x. <br> 53°<br> 78°<br> (10x - 1)º
KatRina [158]

Answer:

Value of x = 5

Explanation:

Given:

Angle 1 = 53°

Angle 2 = 78°

Angle 3 = (10x - 1)°

Find:

Value of angle x

Computation:

Using angle sum property of triangle

⇒ Angle 1 + Angle 2 + Angle 3 = 180

⇒ 53 + 78 + (10x - 1) = 180

⇒ 131 + 10x - 1 = 180

⇒ 10x + 130 = 180

⇒ 10x = 180 - 130

⇒ 10 x = 50

⇒ x = 50 / 10

⇒ x = 5

Value of x = 5

dmitriy555 [2]
Dark Matter only: detected through its gravitational attraction, has mass, most common form of mass in the halo of the Milky Way Galaxy, likely to consist of subatomic particles
Dark Energy only: inferred to exist from the measured acceleration of the universe's expansion, the proposed source of a universal repulsive force
BOTH: the universe contains more of this than it contains matter made from atoms, we do not know what it is made of
NEITHER: blocks light from stars behind it, "dark" because it emits only infrared light

How is science involved in the exploration for oil and natural gas? How is technology involved in this exploration? The Big Sque
Leto [7]

Answer:

A. Geology

B. Computer aided designs

C. Dead organisms in the oceans

D. Helps in converting dead organisms into oil and gas

Explanation:

The oil and natural gas are buried under layers and this requires a good knowledge of "geology". Furthermore, equipments must be built to explore this oil and natural gas

Involvement of Technology has to do with "Computer aided models" being generated. Seismic surveys and satellites used to collect data.

Oil and gas began as dead plants and animals living in the ocean millions of years ago.

Role of sedimentation: the Organisms in the ocean died and went to the bottom of the ocean, where a layer of sediment would cover them. Over the years, alternating layers of dead organisms and sediments were formed. As the layers bottled up, the immense pressure and heat converted the dead organisms into oil and natural gas.
