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 match the correct word to the correct definition. Question 1 options: The Seneca Falls Conference (1848) Urban Suffrage S
larisa [96]

Answer:

1 The Seneca Falls Conference (1848)  

2 Suburban  

3 Density

4 Suffrage

5 Urban  

6 Rural

Explanation:

1. First meeting to begin working for women’s rights organized by Elizabeth Cady Stanton and Lucretia Mott. The Seneca Falls Conference (1848)  

That was indeed the very first official public meeting on the subject of the right to vote for women.  It took more than 70 years to make it become a reality.  This meeting held in New York State, attracted about 300 people, mostly locals, for a 3-day event discussing the women's rights in general and the right to vote in particular.

2. Is a community lying just outside of a larger city area. Suburban  

Suburban means it's not the country side, but it's not the big city it's located next to either.  Suburban areas are mostly residential areas where people live but go to the city to work.  Those areas are filled with houses, restaurants and shopping malls mostly, not corporate offices (they are located downtown, in the city).

3. Refers to the number of people that live in a given urban area. Typically measured by either the square meter or square mile: Density

That's the measure of the number of people living in a given space.  It could be a city, a state or even a country.  It's simply calculated by dividing the number of people by the area they live in.  Based on that, you can say for example that Canada has a people density much lower than the US... because for about the same territory (area), much less people live in Canada.

4. The right to vote in political elections: Suffrage

That's why we called "suffragettes" the people fighting for the right to vote for women.  "Suffrage" also indicates any form of formal votation, like a referendum, in which a very large portion of the  population is invited to cast their vote for or against a resolution.  The issue at hand can be an election, as well as any other state matter.

5. A town or a city area:  Urban

That's where most people work in big countries.  The people go to the city/town to work into offices for example.  That's where the downtown part of the city is.  Some people might live in the city, while others live in the suburban areas around the city.  We often describe the city as the center of the donut and the suburban area are the ring of the donut.

6. Countryside rather than the town, the areas located outside of urban and suburban areas. Typically, thought of as primarily agricultural, it does refer to all areas outside of cities and suburbs such as swamp, forest and mountain areas too:  Rural

This is where food is grown through large fields of plantations, or bovine farms.  The houses are far apart and the roads are much smaller because there is much less traffic, due to having less people transiting.  That also includes areas that are not suitable for buildings like lakes, forests or mountains.

Explain how the shading of the direct light of the sun causes a lunar eclipse.
creativ13 [48]
The lunar eclipse happens when the Moon goes through the Earth's shadow. Earth dependably has a shadow, which is made by the Sun. On those uncommon events when the Moon, Earth and the Sun are altogether arranged perfectly, the Moon goes through this shadow.This would happen each full moon if the Moon circled around the Earth in an indistinguishable plane from the Earth circles around the Sun.

Plate boundaries are often grouped into two different categories. Subduction zones are examples of ___________ boundaries while
Fittoniya [83]

Answer:

Convergent and divergent plate boundaries

Explanation:

In a convergent plate boundary, two plates move towards each other. Due to the impact, the heavier tectonic plate subducts beneath the lighter plate. This results in the formation of a subduction zone, and there forms a trench above this zone. The rocks at greater depths, melts and mixes up with the magma and eventually rises upward, towards the surface in the over-riding plate, giving rise to the formation of volcanoes and volcanic arcs.

In a divergent plate boundary, two plates move away from one another. Due to this opposite motion of plates, there occur cracks on the seafloor and land areas, from where the magma comes out. With continuous spreading, there forms a ridge, which is commonly known as the mid-oceanic ridge. This type of plate boundary is responsible for the formation and expansion of the ocean basin. For example, the mid-Atlantic ridge.

How does the rock cycle interact with the hydrologic cycle? When answering this
Sergeu [11.5K]

Explanation:

Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.
