Heat from the earth's interior reaches the surface through a combination of convection and conduction.
Geothermal heat reaches the Earth's surface through conduction, which involves the slow transfer of heat through the Earth's crust, and through convection, where hot molten rock rises towards the surface, bringing heat along with it.
Imagine the mantle (the hot bit under the Earth's crust), like a lava lamp. The hot magma, which has been heated right down at the very bottom, near the outer core, is less dense then the rest of the magma. It rises, like your lava lamp bubble, until it reaches the crust. If it's hot enough, the magma can melt it's way through to the surface, causing those things we call volcanoes to form.
The Earth's surface is heated by the sun through a process called solar radiation. Sunlight, which consists of energy in the form of electromagnetic waves, reaches the Earth and heats up its surface when it is absorbed by land, water, and other surfaces. This energy is then retained and warms the Earth's surface.
One example of an interaction between the Earth's interior and the atmosphere and surface is volcanic activity. When magma from the Earth's mantle reaches the surface through volcanic eruptions, it releases gases and ash into the atmosphere, affecting weather patterns and air quality. Additionally, the heat from volcanic activity can influence climate and contribute to the formation of new landforms.
FALSE: gravity cannot force magma upwards, gravity can olny force downwars. the reason magma shoots from the earths interior is because the pressure from the magma trying to push through the force gravity causes an eruption.
A body wave is a seismic wave that travels through Earths interior.

The earths interior is cold
Energy is transferred between the earths surface and the atmosphere via conduction, convection, and radiation. Conduction is the process by which heat energy is transmitted through contact with neighboring molecules.

conduction because there is more heat in space then there is in earth
it is heated by conduction by the earths atmosphere
The speed of the waves that travel through the interior can tell the density of each layer of the Earth. Some waves can make it through certain layers, but not others.
Magma that reaches the Earth's surface is known as lava.
