Answer 1

The Earth is an active planet with significant geological activity driven by plate tectonics and affected by a complex atmosphere and cosmic impacts. Its core, mantle, and crust contribute to various surface phenomena, and its atmosphere is critical to climate and weather patterns.

Step-by-step explanation:

The Earth is a dynamic and evolving planet, significantly influenced by its internal and external factors. Seismic waves have provided insight into the Earth's internal structure, revealing a metal core, silicate mantle, and a crust composed of oceanic basalt and continental granite. Earth's geological activity is driven by plate tectonics, which is responsible for a myriad of surface phenomena, including mountain building, rift zones, and volcanic eruptions, which constantly reshape the planet's surface. Additionally, the global magnetic field, generated in the Earth's core, produces the magnetosphere, trapping charged atomic particles.

Our atmosphere, which influences the Earth's climate, consists mainly of N₂ and O₂, with trace gases like H₂O, CO₂, and O₃, impacting atmospheric pressure and composition, further affecting weather patterns. The atmospheric composition has changed over time, initially lacking O₂ and later incorporating it through photosynthesis, which has played a significant role in Earth's climate and the greenhouse effect. Furthermore, Earth and Venus stand out among terrestrial planets for their significant geological activity, with Earth being unique in its ongoing plate tectonics mechanism. Cosmic influences, such as meteor impacts, have also played a crucial role in Earth's geological history, including mass extinctions and the evolution of planetary surfaces.

Answer 2

Complete question:

Fill in the blanks.

The earth is ______ (warming, cooling, static, dynamic). This trend most closely follows trends in the Earth's ______ (albedo, distance from the sun, energy input from the sun, atmosphere). Within the Earth's ______ (albedo, mantle, atmosphere, crust) the component that is likely most responsible ______ (carbon dioxide, magma, water, humans).

Answer:

The earth is warming. This trend most closely follows trends in the Earth's atmosphere. Within the Earth's atmosphere is the component that is likely most responsible for carbon dioxide.

Step-by-step explanation:

Carbon dioxide (CO₂) is a gas that, among other gases, composes the atmosphere, mainly the troposphere, which is closest to the Earth. The balance of this gas in nature is very complex and involves interactions between the atmosphere, the plants, and the oceans.

The current increase in CO₂ is a responsible component of the greenhouse effect involved in global warming and climate change. The rise in CO₂ is possibly the best documented.

The atmospheric increase of CO₂ follows a natural fluctuation trend that has been happening throughout the whole Earth´s history. It has been proven that the current rise in CO₂ concentration overlaps the expected variation and that the reached levels at the moment exceed the highest past registered levels. This substantial increase must be related to human activities.
