Which piece of land doubled the size of the United States? Florida Purchase Louisiana Purchase Mexican Cession.
Answer:
Mexican Cession.
Explanation:
Well, first of all, the Louisiana Purchase and the Florida Purchase are both based in the U.S., so it would be impossible that it could be twice the size as the land in the U.S.
The Louisiana Purchase of 1803 to become part of U.S. territory doubled the size of the country
The Louisiana Purchase entails an acquisition of the Louisiana territory from Napoleonic France in the year 1803.
The Purchase brought into U.S. about 828,000 square miles of territory, thereby, doubling the size of the country.In conclusion, the Louisiana Purchase of 1803 to become part of U.S. territory doubled the size of the country.Hence, the Option B is correct.

Much of Eastern Europe is characterized by
Question 1 options:
dry winters and warm, wet summers.
cold, snowy winters and hot summers.
a humid subtropical climate.
moderate average temperatures.
Answer:
cold snow winters and hot Summers
Explanation:
most of them have cold winters and warm to hot Summers
Much of Eastern Europe is characterized by cold, snowy winters and hot summers. The correct option is B. Europe's eastern and central regions are covered by the continent's climate. The cold, long-lasting winters and primarily hot summers are the climate type's main characteristics.
Why is Eastern Europe so cold?
Around a high-pressure system in the northern hemisphere, air moves clockwise. Our air is currently coming from the east and bringing cold temperatures because of the high pressure over Russia. If this air is warmed or cooled down during its journey, depends on the route it takes.
Midlatitudes define Eastern Europe. A large portion of the area has a humid continental climate. Summers are hot and have snowy winters. The warm ocean currents that help Western Europe's climates remain temperate do not benefit Eastern Europe.
Thus, the ideal selection is option B.

Answer:
The correct answer is C. The names of January, March, May and June mean different gods.
Explanation:
-January is the first month of the year in the Gregorian calendar and has 31 days. It takes its name from the god Janus, represented with two faces, the spirit of the doors and the beginning and the end.
-March is the third month of the year in the Gregorian calendar and has 31 days. Its name derives from the Latin Martius, which was the first month of the Roman calendar. Martius in turn is derived from Mars, the Roman god of war.
-May is the fifth month of the year in the Gregorian calendar and has 31 days; but it was the third month in the ancient Roman calendar, where January and February were at the end of the year.
The origin of its name derives from the Roman goddess Maia, whose festival the Romans celebrated this month they called Maius.
-June (from the Latin Iunius, month of Juno) is the sixth month of the year in the Gregorian Calendar and has 30 days. It was the fourth month in the Roman calendar, where January and February were at the end of the year. It received the name it bears from the goddess Juno.

this layer of earth’s atmosphere has the highest density of any atmospheric layer and contains most of the water vapor in the atmosphere.
The layer of earth’s atmosphere that posses the highest density of all the atmospheric layer, which also contains most of the water vapor in the atmosphere is Troposphere.
The troposphere can be regarded as the lowest layer of Earth's atmosphere.
This troposphere can be described as the layer that occupied about 80% of the atmosphere, it is in this layer that most of the clouds are located.

Explain any 5 factors that affect the climate of India
Answer:
5 factors that affect the climate of India are:
1. Latitude: It is the value of latitude which determines tin which region of the earth India is located and based upon it the climate gets affected.
2. Altitude: It is a type of elevation in which the air pressure is very low and thus the temperature decreases which causes a cool climate.
3. Vegetation: High amount trees causes increase amount of rainfall, whereas less cover of forest leads to low amount of rainfall which in turn affects the climatic condition.
4. Wind: It is the nature of the wind which affects the climate. Warmer wind paves wave for colder climate and vice versa.
5. Topography: The location of India in Earth plays a major role in determining the climatic condition of the country.

where do new sections of crust come from during seafloor spreading?
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.

Which layer of earth is liquid
Answer:
The Outer Core & Inner Mantle
Explanation:
The crust and the inner core are solid, whereas the outer core and inner mantle are liquid. The outer mantle is semi solid. The inner core is solid due to the massive pressure on it. Scientists theorize that the heat of the solid inner core is keeping the outer core in a semi-liquid state which allows the inner core to spin at a slightly different rate than the rest of the earth. This gives the earth its magnetic poles which diverts damaging cosmic rays from colliding with earth. The theories are the result of measurements during volcanic activity and sound waves. The mantle is a plastic solid of varying densities which allow convection currents to flow molten rock towards the earth's surface resulting in volcanic activity, tectonic plate movement, earthquakes, and movement of continents.
Have a great day! :D
Answer:
The Outer Core.

Is the density of an object and the hardness of an object related? Why or why not? PLZZZ
Yes, Density is directly related to the mass and the volume. In fact, it tells us of the exact relationship between the two. To find an object's density, we take its mass and divide it by its volume
Answer:
Answer Wiki. Since hardness measurement involves only surface of the material, bulk density of the material does not have any explicit relation with the hardness. Materials are usually subjected to microstructural and/or chemical changes in the surface by carbiding, nitriding and other processes, many times by cold working.

what are sea breeze and land breeze *long answer though*
Answer:
sea breeze is a breeze that comes from sea and goes to land land breeze is the opposite so it would be land breeze is breeze coming from the land going to the sea pretty easy if you ask me
Explanation:
Answer:
Sea and land breezes occur due to the difference in the cooling rates of land and sea.
Sea breeze (occurs during the day):
During the day, land gains heat quicker than the sea. Air directly above land is thus heated up and rises due to expansion (larger volume, lowered density). Air from above the sea thus moves towards the land to occupy the space previously occupied by the air above land, from an area of high pressure to an area of lower pressure, forming wind.
Land breeze (occurs at nighttime):
At night/evening, land loses heat quicker than the sea. Air directly above the sea is thus warmer. It rises due to lower density. Air from above land thus moves towards the sea to occupy the space previously occupied by the air above the sea, from an area of high pressure to an area of lower pressure, forming wind.
The greater the temperature difference between the land and the sea, the stronger the wind.
