1. What type of heat transfer causes the movement of tectonics plates.

1 answer:

4 0

1) heat from radioactive decay in the core of the Earth heard the mantle.
2) Plates move averagely only a few cm a year, this has been happening ever since the planet formed and cooled to give a thick crust so this movement has added up over many years to move plates far from where they started.
3) because the mantle is heated and is able to flow slowly, convection currents are set up which cause the plates on the crust to move.

Which of the following is Not a Greenhouse Gas?

polet [3.4K]

Answer:

N₂

Explanation:

The primary greenhouse gases in the atmosphere are carbon dioxide, methane, nitrous oxide, water vapour and ozone. These gases allow sunlight to reach the Earth's surface unhindered. The sunlight heats the surface. The heat as infrared reradiated to the atmosphere, the greenhouse gases absorb the heat energy. They do not allow heat to escape back trapping' the gases in the lower atmosphere.

Nitrogen is an inert gas present in the atmosphere is about 78%.

Only some nitrogen-fixing bacteria such as Rhizobium which fixes atmospheric nitrogen into the soil.

Thus, N₂ (nitrogen) is not a greenhouse gas.

Question 5 (2 points) Which of the following is a primary producer? an oak tree O a puffball mushroom a mockingbird a soil bacte

Burka [1]

The correct answer is A. An oak tree

Explanation:

The term "primary producer" is used to describe organisms that can produce their own energy without feeding on others, this includes plants and algae that produce food and energy through photosynthesis using light and other inorganic compounds. Additionally, the primary producers can be identified because in ecosystems they are always on the first level and they are eaten by others.

According to this, the one that is a primary producer is an oak tree because this is a type of plant and therefore can produce its food through photosynthesis different to others that need to feed on other organisms to obtain energy.
