This type of volcano is called a cinder cone volcano. Unlike a composite volcano or a shield volcano, a cinder cone volcano is characterized by a missing chunk near the top. This crater is a result of violent explosions followed by the falling of large quantities of debris and ash.

A convergent plate boundary forms when two tectonic plates (large plates that make up the Earth's surface) move towards each other. When they meet, the higher density plate goes underneath (subducting) under the other. This is the type of plate boundary happening along the west coast of the United States. Divergent plate boundaries occur when two tectonic plates move apart. This process, over millions of years, can form ocean basins. As the divergent plate boundaries continue to move apart, new rock is formed between them. This type of plate boundary is taking place in the center of all modern ocean basins. Transform plate boundaries form when two tectonic plates slide against each other. This is occurring in California at the San Andreas Fault. Strike-slip faults are structures that form along transform plate boundaries.

Along convergent plate boundaries, friction from the subducting plate causes earthquakes. These quakes form deep within the Earth and can cause significant damage to the Earth's surface and human developments upon it. An example of a convergent boundary that causes frequent earthquakes is the west coast of the United States. While tornados, tropical storms, and tsunamis created by mass wasting are all natural disasters; they are typically not the result of plate tectonics.

Both the Hawaiian and the Galapagos Islands are formed from what type of volcanoes?
Both the Hawaiian and the Galapagos Islands are formed from what type of volcanoes?
Tap to see back →
Both the Hawaiian and the Galapagos islands are formed by 'hot spots' in the Earth's mantle. As the tectonic plate passes over these hot spots, some mantle pushes through to form a volcano beneath the ocean, which gradually builds itself tall enough to become an island. When the plate moves away from the hot spot, the process starts over, and another island forms.

Contrary to what many people think, the seasons are caused by the amount of light that the surface of each hemisphere of Earth receives during different parts the year. Because of the tilt of the Earth's axis and its rotation, certain months of the year result in more direct sunlight, but not necessarily because they are closer to the sun. The Northern hemisphere receives less sunlight during some months when the Earth's axis is tilted away from the sun; the resulting season is winter. Each ray of sunlight is spread out over more distance at the poles, whereas the warmest areas (at the equator) get the most direct sunlight. When Earth's axis is pointed towards the sun, the resulting season is summer in the Northern Hemisphere and winter in the Southern Hemisphere.

The correct response is **tilt of the Earth.**The Earth is tilted at an angle of 23.5 degrees. This tilt allows seasonal differences to exist on the Earth since each region is pointing towards the Sun at different angles throughout the year.

Unlike the other processes, driving a hybrid vehicle does not actively remove carbon from the atmosphere. Trees and native flora that are planted absorb atmospheric carbon, fossilization removes carbon from the active recycling of carbon, and carbon dioxide readily dissolves in seawater. Driving a hybrid car releases less carbon into the atmosphere than driving one powered solely by fossil fuels; however, driving a hybrid vehicle does not actively remove carbon from the atmosphere. Hybrid vehicles produce fewer carbon emissions, but they do not take carbon out of the atmosphere.
