The Great Plains of the United States have a steppe and grassland climate.true or false?

The sun's energy heats the surface of the planet, warms the atmosphere, fuels photosynthesis, causes evaporation, controls the weather and water cycles, and drives ocean currents.

What are the Earth system's two main energy sources?

• Only a few factors account for the majority of the energy in the Earth system: solar energy, gravity, radioactive decay, and the rotation of the Earth.Many surface processes, including winds, currents, the hydrologic cycle, and the entire climate system, are powered by solar energy.

• For food, almost all life on Earth either directly or indirectly depends on solar energy.Solar energy is directly used by producers.Through a process known as photosynthesis, they take in the sun's energy and transform it into nutrition.

• Autotrophs, often known as producers, include fungi, bacteria, algae, and plants.A change in one sphere may result in a change in another because the spheres interact with one another.

• In addition to extracting nutrients and water from the soil, plants also emit water vapor into the sky.All life on Earth is found in the biosphere. A renewable energy source is solar power.

• The energy of the sun is produced by the sun itself.The sun is mostly composed of hydrogen and helium atoms in a plasma state, like the majority of stars.Nuclear fusion is the method used to power the sun.

• Only a few factors account for the majority of the energy in the Earth system: solar energy, gravity, radioactive decay, and the rotation of the Earth.Many surface processes, including winds, currents, the hydrologic cycle, and the entire climate system, are powered by solar energy.

• The sun is the primary and only source of energy on Earth.Sunlight is used by plants to create their sustenance.Additionally, it is kept in the form of biomass energy in both plants and animals.Solar energy has been captured and stored in fossil fuels.Additionally, it provides wind energy.

• 1 Internal sources of energy are those that derive their power from the earth itself.The heat produced by nuclear decay and gravity both come from this source.

• 2. Energy from external sources: Energy from external sources originates from places other than the earth.It is the power that the sun provides.

Explanation:

1. The purpose of geographic tools is to give a useful perspective and representation of a landscape to the view. For this reason geographic tools tell us about locations and the distances between locations. They also strive to give some type of context to the areas in question by relating them to information in a legend and to surrounding areas.
2. Scales are extremely important in geography because they allow very large distances to be reduces to mere centimetres on a digital or paper map. It would be very impractical to produce a map the size of a small country in order to travel between two cities that are far apart, but scale solves this problem. In digital applications the scale changes as the user zooms in and out, giving even more flexibility.
3. Topography can be used on maps to delineate areas. An example would be the rough-looking terrain that is used in mapmaking to denote mountains. When the viewer sees the terrain marked as mountains or the blue areas marked as bodies of water, he/she knows that at those points on the map the areas are distinct to those marked with other colours or textures.

When tectonic plates rub against each other the friction causes earth ranges to slip and move around making whatever's on top shake and move as well.

The correct answer is - 3. maize.

The maize was the basis of the diet of the civilizations of Mesoamerica. It was one of the first wild plants in which the people from this region saw a potential as a big and stable food source, so they started to farm it. All of the civilizations we know from this region, like the Olmecs, Toltecs, Mayans, Aztecs, formed and developed their civilizations around the food source that was provided by the maize.
