First, the decomposition of radioactive elements causes heat in the interior part of the Earth. Then heat moves to the core. After that, heat slowly rises to the mantle and creates a convection current. Then lithospheric plates move in the asthenosphere due to the rising and sinking of materials. And finally, the process repeats as a cycle. That is the correct order of how convection current happens.
What is Convection Theory?Convection Theory was put forward by Arthur Holmes and Harry H. Hess and then further developed by Robert S. Dietz.
The evidence underlying the Convection theory is the result of research on the age of the seabed which proves that the farther from the mid-ocean ridge, the older the rock is. This means that there is a movement originating from the mid-oceanic ridge region in the opposite direction due to the influence of convection currents originating from the layer beneath the Earth's surface.
Other evidence is the presence of mid-oceanic ridges, such as the mid-Atlantic ridge and the Pacific-Atlantic ridge.

What are Earth's natural defenses against solar storms?
Even though there may be a small amount of particulate radiation that reaches the Earth's surface, the magnetosphere and Earth's atmosphere continue to shield our planet from cosmic rays and charged solar particles.
Plasma, mostly electrons, and protons, which are highly charged particles, make up the magnetosphere. Differing parts of the magnetosphere have different concentrations of these charged particles.
Most of the solar material that is being swept towards us at 1 million mph or more by our star is deflected by it. The unrelenting activity of these solar particles, which screen humans from the Sun's UV radiation, might deplete the Earth of its protective layers if the magnetosphere weren't present.

The Galilean satellites are a group of Jupiter's four sizable moons. Europa is the smallest and second-closest to Jupiter of these four. Its 1560 kilometre radius makes it significantly smaller than the Moon. This size of object is anticipated to dissipate its interior heat in a relatively short amount of time.

Why do pumpkins get so big?
Large quantities of water, sugar and plentiful sunlight must be present to grow giant pumpkins. They do not get excessively tall but very wide because gravity holds them in place.

The correct option is option (c), i.e, both (a) and (b) are correct. Sierra Nevada mountain is created by seismic fault and Lewis overthrust in glacier national park in Montana is created by folding.
The Sierra Nevada Fault, an active seismic fault in California's Sierra Nevada mountain massif, runs along its eastern boundary. It extends around 600 km (370 mi) from just north of the Garlock Fault to the Cascade Range, forming the eastern escarpment of the Sierra Nevada.
The Lewis Overthrust is a Rocky Mountain thrust fault structure that can be found in the bordering national parks of Waterton Lakes in Alberta, Canada, and Glacier in Montana, the United States. The structure was created when two tectonic plates collided about 170 million years ago, pushing a wedge of rock up to several miles thick 50 miles (80 kilometres) eastward, where it now lies on top of the softer rock from the Cretaceous period, which is 400–500 million years younger.

What is sediment ?Common sedimentary rocks are sandstone, limestone, and shale. These rocks often begin as sediments that are carried by rivers and deposited in beach and oceans. Upon burial, the sediment loses moisture and is cemented into rock.Rocks larger than small particles of clay are called sediments and are moved by water. Fast-moving water can pick up, suspend, and displace larger particles than slow-moving water. High concentrations of suspended sediment can displace vegetation, invertebrates and insects in riverbeds. This can affect the fish's food sources, resulting in smaller and fewer fish. Sediment can bury and suffocate fish eggs.

a. Some sediment is brought to glaciers by streams
b. Sediment that is carried and deposited by a glacier is a moraine

By releasing less moisture into the sky, cold ocean currents can stop the formation of glaciers, and stronger ocean currents can bring colder water to the surface, which cools the land. The impact of continental drift on glaciers, ocean currents, and the overall climate is accurately described by this phrase.
Due to the fact that melting glaciers hold their water on land, runoff significantly increases the amount of water in the ocean, raising the sea level.
When the climate changes, glaciers, and ice caps react to the changes in the atmosphere and the ocean, which also clearly indicates that the climate is changing globally.

When individual water molecules escape as gas from liquid water, the process is called Evaporation. when water vapor molecules in the air bind together to form liquid water droplets, the process is called Condensation.
A liquid turns into a gas through evaporation. The forces of attraction between molecules cannot stop them from drifting away when a liquid is sufficiently heated or when the pressure on the liquid is sufficiently reduced. As a result, the liquid evaporates into a gas.
The transition from a vapor to a condensed form is known as condensation (solid or liquid).
The forces of attraction between molecules in a gas prevent the molecules from drifting apart when the gas is sufficiently cooled or, in many situations, when the pressure on the gas is increased sufficiently. As a result, the gas condenses into a liquid or a solid.
