Why do you think eruptions of volcanoes like Mt. Pinatubo might have a cooling effect on the Earth’s surface?

Why is the shape of the magnetosphere not spherical like the shape of the earth

Choose the answer that best fits the blank. Hundreds of years ago, geographers first noticed that many of Earth's continents have shapes that seem to "fit together" like a big puzzle that was broken up. Because of this, they theorized that the continents had slowly changed position over time. The explanation for exactly how this movement occurred, however, did not become clear until geologic research in the 1960s led geologists to formalize the theory of _______ . This scientific theory states that continents move because they are a part of a series of plates that form Earth's crust. These plates shift around the planet, moving on a bed of liquid, hot rock known as magma. A.plate tectonicsB. continent driftC. paleomagnetism

What are some changes occurring in the oceans as a result of Earth's current climate conditions?

Who first proposed the continental-drift theory? What three sources of evidence convinced geologists that the theory was correct?

What are the 3 names of the stages of a volcano?

The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and etreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era and of human vilization. Most of these climate changes are attributed to very small variations in Earth's orbit that change the amount of solar energy ur planet receives. The current warming trend is of particular significance because most of it is very likely human-induced and oceeding at a very rapid rate not seen in the past 1,300 years. Earth-orbiting satellites and other technological advances have enabled Fentists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. {thing!
