Then it is moving towards earth
Gennadij [26K]3 years ago

Answer:

If a star is moving toward Earth, its light waves appear to be squeezed together. The decreasing distance between Earth and the star effectively shortens the wavelength of the starlight received by Earth. This shifts the star's spectral lines toward the blue end of the spectrum.

Answer:

C. It is larger in urban areas

Explanation:

  • Carrying capacity is the number or the amount of pressure of species on the earth's ecological system can bear or can carryforwards and can be sustained by giving food, water, and necessity available to the environment.
  • The ecological footprint is a measure or a way to estimate the pressure on the natural resources by these species by taking in the future possibilities and limitations. Estimated in terms of the demands and the biocapacity of the ecosystem.
  • <u>The urban area carrying capacity is a result of interaction of the multiple subsystems and due to the large human activities the urban areas have low levels of the carrying capacity as they are not natural settings and put pressure and huge load over resources.</u>

What historical evidence was used at mt. Pinatubo to indicate there have been multiple large eruptions by this volcano over the
lara [203]

The first notable volcanic activity since 1992-93, when there was dome growth and secondary phreatic explosions in the aftermath of the major 1991 eruption, is a phreatic explosion from the summit crater lake at Pinatubo in November 2021.

<h3>What evidence exists to suggest that the 1991 eruption of Mount Pinatubo rendered lahar unsafe?</h3>

Lahars at Pinatubo since 1991 In the years that followed the devastating eruption in 1991, they deposited more than 0.7 cubic miles (3 cubic kilometers; hundreds of square miles of land were submerged by the debris, which was the equivalent of 300 million dump truck loads, in the lowlands surrounding the volcano.

<h3>How were they aware of the impending eruption of Mount Pinatubo?</h3>

Seismic data and an increase in sulfur dioxide released from the volcano by May 1991 suggested to scientists that the volcano's magma chambers were being filled with new magma. The rapidly expanding lava dome on Pinatubo hinted at a forthcoming large-scale eruption.

The Himalayan mountains by India, Nepal and China are the best example of this.
marysya [2.9K]

Answer:

The Himalayan Mountains by India, Nepal, and China are the best example of a convergent plate boundary.

Explanation:

The Himalayan Mountains are the highest mountain range in the world, but also the most massive one. It acts as a natural boundary between Southern, Southeastern, Eastern, Central, and Southwestern Asia. This mountain range is a relatively young one (geologically speaking), and it has formed because of the collision between the Indian and Eurasian tectonic plates.

When India diverged from Gondwana, it started to move toward Eurasia. After tens of millions of years, the Indian plate hit the Eurasian plate from the south, and with both of the plates being continental and having a boundary with their continental parts, they created a convergent plate boundary. The pressure between the plates has resulted in lifting up the crust, gradually creating a huge mountain range.
