Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

In the northern hemisphere, the sun is lowest in the sky with less radiation in the
schepotkina [342]

The Sun is lowest in the sky with less radiation in the Northern Hemisphere during the winter solstice.

Explanation:

The Earth is not static, but instead it is involved in several different motions. One of those motions is the Earth's tilt. Basically, the Earth is tilted with one of its hemispheres (northern or southern) toward the Sun in half of the year, and then in the other half of the year it is tilted with the other hemisphere toward the Sun.

When one of the hemispheres, lets say the Northern Hemisphere, is tilted away from the sky, and that reaches the maximum, it receives the least solar radiation, and the Sun is the lowest on the sky. That occurs on 21 or 22 December, and it is known as the winter solstice. This date represents the start of the winter for the Northern Hemisphere, thus its coldest period of the year.

The four stages on Earth caused by the tilting are:

  • spring equinox
  • summer solstice
  • autumn equinox
  • winter solstice

When an oceanic plate collides with a continental plate, the continental plate usually slides up and over the denser oceanic pla
KengaRu [80]
The correct answer is B Subduction. Subduction is the process by which an oceanic plate gets dragged under another plate and is eventually destroyed in the mantle. Subduction occurs at convergent margins where two oceanic plates collide or an oceanic and Continental plate collide. Oceanic crust is made of mainly of silica and magnesium which is heavier or denser than continental crust which is composed mainly of silica and aluminium.
The subducting plate melts producing excess magma giving rise to volcanoes along these margins.
